Abstract: A method for adaptive spectral sensing developed for a two-dimensional image (16) made up of picture elements (14). The method calls for illuminating at least one of the picture elements with an input light (18) and deriving a time-varying spectral signal from the input light for that picture element. The time-varying spectral signal is processed with a time-varying reference signal by using a mathematical function such as convolution, multiplication, averaging, integrating, forming an inner product, match filtering, addition, subtraction or division to obtain a processed output value for the picture element and this output value is then used in determining a spectral characteristic of the input light. The time-varying spectral signal is conveniently derived by optical filtering of the input light yielding an optical time-varying spectral signal. This method can be used by itself or in combination with at least one other adaptive technique such as adaptive spatial sensing and/or adaptive temporal sensing.

Abstract: A device that uses two intensity modulated frequency combs to measure distances with high precision and high data acquisition rate without any moving parts and without length ambiguity that is inherent conventional ranging based on two frequency combs. A modulation signal having a repetition rate identical to the repetition rate difference between the two combs is used to do a direct time-of-flight length measurement, hence avoiding the given length ambiguity while harvesting the increased precision of the dual-comb approach.

Abstract: A photodetector includes: a semiconductor substrate; a mesa portion formed on a major surface of the semiconductor substrate to extend along an optical waveguide direction; a first contact layer; a second contact layer; a first electrode; and an air bridge wiring electrically connected to the first contact layer and the first electrode. When viewed in a direction perpendicular to the major surface of the semiconductor substrate, a length of the mesa portion in the optical waveguide direction is longer than a length of the mesa portion in a direction perpendicular to the optical waveguide direction. The air bridge wiring is led out from the first contact layer to one side in the direction perpendicular to the optical waveguide direction, and is bridged between the first contact layer and the first electrode.

Abstract: A multi-channel measurement device for measuring properties of human tissue, may comprise a microcontroller and first and second source/sensor complexes. The first source/sensor complex may include a first housing having a first measurement portion, a first light sensor coupled to the microcontroller and exposed to the first measurement portion, and a first plurality of light sources coupled to the microcontroller and exposed to the first measurement portion. The second source/sensor complex may include a second housing having a second measurement portion, a second light sensor coupled to the microcontroller and exposed to the second measurement portion, and a second plurality of light sources coupled to the microcontroller and exposed to the second measurement portion. The first and second source/sensor complexes are coupled to each other such that the first measurement portion is opposite the second measurement portion and human tissue may be placed between the the first and second measurement portions. The microprocessor is configured with instructions stored in non-volatile memory to individually activate each of the light sources of the first and second pluralities of light sources and to record light intensity detected by the first and second light sources while an individual light source is activated. Each combination of an individually activated light source and one of the first and second light sensors provides a distinct measurement channel for measuring the absorption spectra of human blood and tissue.
