Abstract: A remote sensing system for time-of-flight measurements may comprise an array of laser diodes with Bragg reflectors operating in the near-infrared wavelength range synchronized to a detection system comprising lenses, spectral filters and a photodiode array coupled to a processor. The time-of-flight depth information may be combined with various camera imaging systems. The camera system may comprise a lens system, prism and a sensor. In another embodiment, the data from two cameras may be combined with the time-of-flight depth information. Yet another embodiment comprises an imaging system with another array of laser diodes followed by a beam splitter and a detection system. The remote sensing system may be coupled to a smart phone, tablet or wearable device, and the combined data may provide three-dimensional information about at least some part of an object. Also, artificial intelligence may be used in the processing to make decisions regarding the depth and images.

Abstract: An optical system comprises a wearable device for measuring one or more physiological parameters. The physiological parameters may change in response to stretching of the hand or movement of fingers or thumb of the user, or the parameters may be related to blood constituents or blood flow. The wearable device comprises a light source with a plurality of semiconductor diodes and a detection system that measures reflected light from tissue comprising skin. The semiconductor diodes may be light emitting diodes or laser diodes. The signal to noise ratio for the output signal may be improved by synchronizing the detection system to the light source, increasing light intensity of at least one of the plurality of semiconductor diodes from an initial light intensity, and using change detection that compares light on versus light off for the detection system output. The wearable device is also configured to identify an object.
