Abstract: A medical photometer includes a processor and a memory that stores an instruction readable by a computer. When the instruction is executed by the processor, the medical photometer acquires a first light attenuation of a first light beam that is transmitted through or reflected from a tissue of a living body, and that has a first wavelength, based on a first intensity signal corresponding to an intensity of the first light beam, acquires a second light attenuation of a second light beam that is transmitted through or reflected from the tissue, and that has a second wavelength, based on a second intensity signal corresponding to an intensity of the second light beam, and calculates a light absorber amount that is an amount of a first light absorber in the tissue, based on a ratio of the first light attenuation and the second light attenuation.

Abstract: An optical receiver (100) for detection of light from one or more sources (108) comprises an opaque layer (102) disposed on a first surface. An aperture (104) is formed in the opaque layer. An optical detector (106) has a detection region disposed on a second surface. The first and second surfaces are spaced apart from one another such that light passing through the aperture (104) illuminates a corresponding illumination region (110) on the second surface, and is detected by the optical detector (106) In the event that the detection region overlaps the illumination region. Multiple apertures may be formed in the opaque layer, and/or multiple optical detectors may be disposed on the second surface. The optical receiver may thereby enable optical signals originating at different locations to be detected, and distinguished, over a wide field of view.

Abstract: A pulsed UV laser assembly includes a partial reflector or beam splitter that divides each fundamental pulse into two sub-pulses and directs one sub-pulse to one end of a Bragg grating and the other pulse to the other end of the Bragg grating (or another Bragg grating) such that both sub-pulses are stretched and receive opposing (positive and negative) frequency chirps. The two stretched sub-pulses are combined to generate sum frequency light having a narrower bandwidth than could be obtained by second-harmonic generation directly from the fundamental. UV wavelengths may be generated directly from the sum frequency light or from a harmonic conversion scheme incorporating the sum frequency light. The UV laser may further incorporate other bandwidth reducing schemes. The pulsed UV laser may be used in an inspection or metrology system.
