Abstract: An imaging device includes laser diodes (LDs) generating near-infrared wavelength light, lenses configured to deliver the light to tissue, a first receiver having one or more detectors, and a first part with at least one of the LDs capable of being pulsed. The first receiver receives light reflected from the tissue and is synchronized to the pulsed light and configured to perform a time-of-flight measurement. An infrared camera receives light reflected by the tissue from a second part of the imaging device. The camera captures light while the second part is off, and while the second part is on to generate corresponding signals, and differences the signals to generate an image. An array of LDs generates a grid of spots on the tissue, which is reflected to the camera. A coupled phone, tablet, or computer receives and processes the time-of-flight measurement, the image, and the reflected grid of spots.

Abstract: A system for measuring water quality parameters, such as pH, CO2, alkalinity, and so forth, includes sensors or other measuring components integrated onto a circuit board. The circuit board may be contained within a submersible, watertight housing. A spectrophotometer may be located on the circuit board to measure the wavelength and intensity of light transmitted through the water being tested. Sensors for measuring salinity, pressure, temperature, or other properties may also be included on or near the circuit board. A microcontroller for processing these measurements is located on the circuit board. System components used to direct and filter the water, such as certain pumps, filters, and so forth, may be included in the housing off of the circuit board. Integrating the sensors and other measuring components onto a circuit board allows for a compact, low-cost water-quality-measuring system that is capable of making very accurate and precise measurements.

Abstract: Continuous on-line thin film measurements employ a sensor having a spectrometer for interferometric measurements and a stack of single channel detectors for adsorption measurements. The stack is separated from the spectrometer, which analyzes radiation that emerges (transmitted pass or reflected from) the film, whereas the stack analyzes radiation that has passed through the film multiple times. The spectrometer is (i) positioned directly opposite the source of radiation so that it detects transmitted radiation or (ii) disposed on the same side of the film as is the source of radiation so that the spectrometer detects radiation that is specularly reflected from the film. The sensor includes a broadband radiation source emitting visible to far infrared light which propagates through a measurement cell defined by reflective surfaces exhibiting Lambertian-type scattering. The sensor is capable of measuring thin plastic films with thicknesses down to 1 micron or less.

Abstract: A method for designing a spectral sensing device. The method includes: (1) performing computational operations on a computer, wherein the computational operations determine the positions of diffracted orders of an optical system model that models at least an array of light modulating elements and a diffraction grating, wherein the diffracted orders correspond to respective spectral components of input light to the optical system model, wherein the positions of the diffracted orders are determined at a target plane of the optical system model; and (2) storing the positions of the diffracted orders in a memory, wherein the positions determine corresponding locations for light detectors in the spectral sensing device. The spectral sensing device may be assembled by modifying an existing single pixel camera, i.e., by adding the diffraction grating and adding the light detectors respectively at said positions of the diffracted orders.

Abstract: A method, apparatus and system estimating channel power, and monitoring a frequency spectrum characteristic. A method for estimating channel power includes extracting frequency spectrum information from a received signal, so as to obtain a frequency spectrum of the received signal, estimating power of a central channel in the frequency spectra according to a power value of a flat area of the central channel, and estimating power of a neighboring channel in the frequency spectra according to a power value of a flat area of the neighboring channel. With the embodiments of the present disclosure, the power of the central channel and the power of the neighboring channel may be estimated by using only frequency spectrum information obtained by a single optical receiver, so as to quantitatively evaluate influence of a power imbalance effect, thereby ensuring precision of the power estimation, and reducing effects of nonideal factors on the estimated values.
