Abstract

A remote sensing system comprising laser diodes with Bragg reflectors generating pulsed light that is directed to an object. A detection system receiving some of the light reflected from the object and coupled to a processor configured to measure a time-of-flight. The pulsing may have a phase associated with the modulation frequency, or nanosecond pulses may be used for the measurement. The remote sensing system including the processor is further configured to provide time and position data for a user. The object may comprise the user capable of laying on a supporting surface. The remote sensing system may also be coupled to a camera system to capture images, which may be combined with the time-of-flight measurement. Artificial intelligence may be used to make decisions associated with the images or the time-of-flight measurement. The processor may be coupled to non-transitory computer readable medium and may communicate data to a cloud server.
