Optical sensors have numerous applications in research and development, national defense and commercial markets such as medical diagnostics and process control. Because of the breadth of applications for optical sensors, the challenges to the design and functioning of an optical sensor for a particular purpose requires intimate knowledge of optical, material, and environmental properties that affect sensor performance. These optical sensors range from micro-probes to large devices used for such diverse functions from human health status to standoff monitoring of industrial and environmental conditions. SENSORS addresses all aspects of optical sensors from source and detection technologies, sensor configurations, and processing approaches to applications. The conference is arranged in broad topic categories (e.g. Optical Fibers) and themes for simple access for a researcher in any stage of learning or development. Beyond the topics listed below, SENSORS will be exploring the use of Artificial Intelligence and Machine Learning (AI/ML) as focus for this year’s conference contributed talks are welcomed for this area of research.


Optical Fiber Sensors
Optical fiber sensors, in particular those related to safety, security and defense. These will include both point (interferometric, polarimetric, refractometric, and grating based) and distributed sensor. Examples include, but are not restricted to, gyro, current, magnetic field, radiation, bio and chemical, strain, temperature, pressure, vibrations, DAS, OTDR and OFDR.

Laser based Sensors
Laser Based Sensors are based upon direct and indirect detection of laser light interacting with a target object, which inherently allow for non-invasive measurements with high precision and high accuracy as well as fast response. Thus, demands and challenges for laser-based sensors continue to grow in both science and technology. The topics of Laser Based Sensors subcommittee include laser ellipsometry, laser speckle imaging, laser spectroscopy, laser Doppler vibrometry, laser interferometry, laser light detection and ranging, and laser-based quantum-enhanced sensing.

Optical Biological and Chemical Sensors
This meeting brings together early career and established researchers from academia, industry, and government in the rapidly advancing field of optical biochemical and chemical sensors. Technologies such as fluorescence, Raman and infrared spectroscopy, fiber optics, silicon photonics, nanophotonics and plasmonics have all found recent application in chemical and biological sensing. These sensors utilize similar scientific principles to tackle a wide variety of detection challenges from multiple disciplines. Applications for these sensors addressing the critical needs in health, environment, food, forensics, safety, and security are all a focus of this meeting. A special topical session on optical sensors for disease and pathogen detection is also planned, and abstract submissions for sensors that address these topics are encouraged.

Terahertz Sensors
Innovations in source and detector technologies, tailored electromagnetic materials, and computational intelligence are making the terahertz spectral region (0.1 - 30 THz) much more accessible for innovative sensing concepts.  This session will feature contributions in all these areas, with an emphasis on exploring how the terahertz region provides unique capabilities to detect and recognize unique signatures.

Quantum Sensors
Quantum sensors utilize the quantum properties of matter (such as quantized transitions in neutral atoms, ions, and spin qubits) or quantum phenomena (including entanglement between different qubits or degrees of freedom) to measure physical quantities with unparalleled sensitivity, precision, and accuracy. This meeting aims to cover quantum sensing technologies with real world applications as well as the development of devices and techniques that will advance sensing performance. Topics include:

  • quantum sensors for timekeeping, inertial navigation, magnetometry, thermometry, and other measurements
  • single-photon detection and quantum imaging systems
  • metasurfaces and integrated photonics for quantum sensors
  • enabling optical technologies to improve the preparation, control, and measurement of quantum sensing systems
  • advanced approaches that will push the sensitivity beyond the standard quantum limit
