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.

Abstract: The disclosure is to provide a practical structure of a pulse spectrometer that transmits pulsed light by dividing it through a plurality of fibers for pulse stretching, and makes the divided light beams overlap in a same region on an irradiation surface. A broadband pulsed light from a pulse light source is divided according to wavelength by an arrayed waveguide grating used as a dividing element, the pulse is then correlated one-to-one between time and wavelength while being transmitted through a bundle fiber, and then emitted through an irradiation unit onto an object. The individual light beams output from the individual cores of the bundle fiber are overlapped by a first lens in a substantially same region on a first plane perpendicular to an optical axis, and an image in the first region is projected by second lenses so as to be emitted on the object.
