Optimal Control of Lighting Schedules for Circadian Entrainment using a Wearable Spectral Sensor

The advent of artificial lighting has exposed people to high lighting conditions at night. This has negative impacts on the human circadian system that depends on light for its regulation. Therefore, it is important to develop methods and tools that can measure and regulate our exposure to light. This work prototypes a wearable spectral sensor system that can be used to measure, record and store spectral information of light throughout a period of time. This data is then used as an input a method that was developed to generate optimal light schedules to positively impact the circadian health of people.
