Imagine a world where intelligence is added to all elements of manufacturing. Picture a
manufacturing floor where every single “thing” is able to produce, receive and analyze
data (hence making every “thing“ a “smart thing“). Now, imagine that all “smart things“
are connected such that they can exchange data with each other, analyze the data, and
make and execute decisions. When we move beyond the “thing“ being simply smart, to
a place where we are:
1. Utilizing machine learning, artificial intelligence, and other forms of data science
and analytics to improve manufacturing processes
2. Building digital threads and digital twins for cradle to grave track and traceability,
3. Establishing connected communications within a digital supply chain
then we are moving toward the true meaning of the smart factory. One can imagine the
ease of tracking defects, the opportunity for new digital platforms and business models,
and, most importantly, the change to the way we manufacture. This presentation will
provide a "starter kit" for those on their road to smart factory implementation. Whether
you are a novice or a veteran, this starter kit will teach/remind you of the key elements
to keep in mind as you begin any implementation.

Optical communication networks are supporting a wide range of valuable communication services including residential services, enterprise services, and mobile services. The 5th-generation (5G) wireless brings to optical networks new requirements such as high bandwidth, low latency, accurate synchronization and the ability to perform network slicing and autonomous operation etc. In parallel, fixed broadband services are demanding higher speed, lower latency, wider coverage and better user experience. All these demands are driving the transformation of optical networks to a new generation as witnessed by 50G-PON, 400G-ZR, 800G long haul, FDMA-P2MP, superchannel-capable high-degree OXC, and beyond-C-band WDM. This OSA webinar aims to highlight the exciting technological advances in optical transport and access networks over the last few years and provide new perspectives on what to expect in the 5G era.

All companies have things go wrong in their technical projects, from small things like a
2-week schedule delay to a large-scale product recall. How a development team handles
these issues can make a big difference in their customer relationships, and therefore on
their future business. No customer expects you to be perfect, but they do expect to be
able to trust you when things go wrong, and they expect you to handle the issue in a
professional manner. The Eight Discipline (8D) problem resolution process was
developed for this purpose. In this webinar we will review the process and how to use
it in an effective manner.

Metrology is a founding pillar and a driving force of scientific discovery and understanding. The ability to accurately measure quantities of interest has always been one of the ultimate tests in verifying or subverting scientific hypotheses, ultimately advancing the scientific understanding and engineering applications. Although much progress has been made in all fields of science and engineering over the last century, the state of the art in the metrology of gas and plasma flows has largely remained unchanged, being perturbative and not accurate to the level modern science and engineering requires. In this talk I will discuss the laser diagnostic efforts developed to tackle the matter, by concentrating on the research efforts of our group in this field by utilizing Coherent Rayleigh-Brillouin scattering (CRBS).
CRBS is a four-wave mixing diagnostic technique that relies on the creation of an optical lattice in a medium due to the interaction between polarizable particles and intense laser fields. Single shot CRBS1 has been demonstrated to be the coherent analog of spontaneous Rayleigh-Brillouin scattering in measuring the temperature, pressure, bulk and shear viscosity, speed of sound and polarizability of a gas or gas mixture2. Additionally, CRBS3 has facilitated the in situ measurements of ~5 nm nanoparticles produced in an arc discharge. In this talk, an overview on the theory and experimental aspects of single shot CRBS will be presented. Furthermore, I will demonstrate our recent work in utilizing CRBS for neutral gas flow velocimetry with measurable velocities down to 5-10 ms-1, applicable to atomic and molecular gases and gas mixtures4. Finally, I will discuss the feasibility and working progress towards the use of single shot (CRBS) as a plasma flow and temperature measuring technique for partially ionized gases.

Optical metasurfaces, planar subwavelength nanoantenna arrays engineered for on-demand wavefront manipulation, have emerged rapidly as a powerful tool enabling compact flat optics with dramatically enhanced capabilities. When integrated with active elements, the pixelated, thin device architecture further facilitates dynamic tuning of local and global optical responses. In this talk, I will discuss opportunities and challenges of employing metasurfaces in a variety of optical systems that are traditionally bulky and complicated. Leveraging advanced materials, designs and architectures, I will further describe our efforts to develop ultra-compact all-dielectric metasurface optics with unprecedented performance, such as ultra-wide field-of-view metalenses, solid-state active meta-optics, new imaging and sensing architectures, etc. The recent progress shows that the judiciously engineered optical metasurfaces can significantly boost the performance, allow novel functionalities and effectively reduce the size, weight, power and cost (SWaP-C) of future optical systems.

Human activity Recognition (HAR) are explored in video-based computer vision domain and sensor-based ubiquitous research areas. Vision-based human action or activity recognition approaches are based on RGB video sequences, or depth maps, or from skeleton data – taken from normal video cameras or depth cameras. On the other hand, sensor-based activity recognition methods are basically based on the data collected from wearable sensors having accelerometer, gyroscope, or so on. There are numerous applications on HAR, however, the healthcare, elderly support, and related applications become very important arenas with huge social and financial impact. Due to the advent of various IoT sensors, it becomes more competitive as well as easier to explore different applications.

As genetically-encoded fluorescence indicators of calcium and membrane potential evolve and improve, optical methods advance to exploit their full potential for neurophysiology research. With so many choices, the neurophysiologist needs a systematic framework for comparing and predicting the performance of indicator/imaging system combinations. Dr. Foust will present such a framework for which the key figure of merit is the signal-to-noise ratio of the time-varying fluorescence signal. In this context I will also describe our efforts to boost photon budgets for membrane potential and calcium imaging with multi-focal two-photon and light-field imaging systems.

The benefits of systems engineering are widely promoted with varying degrees of understanding. This
webinar is based on many years of experience designing and building complex systems incorporating all of the engineering disciplines (optics, mechanics, electronics, and software). For me, understanding and
using systems engineering has been a natural approach driven by my instincts (even before it was a newfound contemporary “thing”).
Systems engineering is about balance and perspective. The word “system” conveys the inherently multidisciplinary nature of the work. The engineering work is fundamentally to hold a perspective that makes sure nothing is overlooked that could affect the outcome and to make sure that the best balance is achieved between all of the competing needs and wants that drive the creation of the system in the first
Systems engineering starts with requirements, and then systems engineering follows on to serve and protect the requirements by constantly evaluating error budgets and the compliance of the system with the requirements as the system is designed and built.
In this webinar you will learn by example:
- How to approach the development of requirements that satisfies your stakeholders
- How to use one sentence definitions to clarify ideas and gain consensus
- How to define and manage expectations
- How to gain and confirm requirements “completeness”.
