Incubator on Wearable Dosimeters and Light Loggers: Performance, Miniaturization and Health Metrics

04 - 06 February 2024
Optica Global Headquarters, Washington, DC, USA


  • Manuel Spitschan, Technical University of Munich
  • Rigmor Baraas, University of South-Eastern Norway
  • Francisco Imai, Chair, Optica Color Technical Group

Program Overview

Wearable dosimeters and light loggers allow for the measurement and evaluation of personalized optical radiation. Over the past few years, there has been a surge of research and development on such devices for the purpose of supporting health and well-being, with a specific focus on optimal light exposure for circadian entrainment and myopia control. The focus of this Incubator is to advance the field by bringing together key players in this area of research and technological development.

Scope and Topics

The Incubator aims to discuss the current state-of-the-art wearable dosimeters and light loggers. It will explore the differences and similarities in needs across fields of research, including UV, spectral, and IR properties; directional properties; form factor; and storage & battery capacity. Finally, it will seek to find opportunities for technical development vis-à-vis better performance and miniaturization.

Through panels, breakout sessions, moderated discussion periods, and informal networking, this Incubator seeks to answer the questions:

  • How can wearable dosimeters and light loggers be miniaturized for non-invasive and ubiquitous wear?
  • What technical opportunities are there for improving the capability and availability of wearable dosimeters and light loggers?
  • How should data from wearable dosimeters and light loggers be analyzed and summarized and related to health outcomes? Is this personalized, health-related data and if so, how should it be treated?
  • Is there a need for certification of wearables dosimeters and light loggers and how could that be achieved?

This incubator is supported in part by:

Reality Labs Research
