Abstract: A method for correcting frequency offset in a dual comb spectroscopy system is provided. The method includes causing a first laser (L1) generator to transmit L1 pulses at a repetition rate of a first frequency and causing a second laser (L2) generator to transmit L2 pulses at a repetition rate of a second frequency. The method also includes interrogating a reference material using a combination of the L1 pulses and the L2 pulses and capturing reference cell pulses. The method further includes interrogating a material of interest using the L1 pulses and capturing material of interest pulses. The method includes determining a frequency jitter based on the captured reference cell pulses and the combination of the captured material of interest pulses and the L2 pulses.

Abstract: Pressure variations within a solid propellant rocket motor produce like variations in the optical radiance of the motor exhaust plume. The periodicity of the variation is related to the length L of the rocket motor or speed of sound in the rocket motor combustion chamber to length ratio a/L. The optical radiance is collected and converted to electrical signals that are sampled at or above the Nyquist rate. An array of single-pixel photo detectors is well suited to provide amplitude data at high sample rates. The sampled data from the one or more detectors is assembled to form a high fidelity time sequence. A window of sampled data is processed to form a signal frequency spectrum. The mode structure in the frequency spectrum is related to the rocket motor length or speed of sound in the rocket motor chamber to length ratio. The rocket motor length or speed of sound to length ratio is used alone or in combination with other information to either classify or identify the rocket motor.

Abstract: A device images radiation from a scene. The scene can include two materials with spectral characteristics in different radiation wavelength regions. A static filtering arrangement includes two filters with different passbands corresponding to the two wavelength regions. An image forming optic forms an image of the scene on a detector. The radiation from the scene is imaged simultaneously through an f-number of less than 1.5 onto two detector pixel subsets. The imaged radiation on one pixel subset includes radiation in one wavelength region. The imaged radiation on the other pixel subset includes radiation in the other wavelength region. Electronic circuitry produces a pixel signal from each detector pixel. The pixel signals include information associated with absorption or emission of radiation in one of the respective wavelength regions by the two materials. The electronic circuitry determines the presence or absence of each of the two materials based on the pixel signals.

Abstract: The present disclosure generally relates to hyperspectral spectroscopy, and in particular, to systems, methods and devices enabling a single-sensor hyperspectral imaging device. Hyperspectral (also known as “multispectral”) spectroscopy is an imaging technique that integrates multiples images of an object resolved at different narrow spectral bands (i.e., narrow ranges of wavelengths) into a single data structure, referred to as a three-dimensional hyperspectral data cube. Data provided by hyperspectral spectroscopy allow for the identification of individual components of a complex composition through the recognition of spectral signatures of individual components within the three-dimensional hyperspectral data cube.

Abstract: A 2-D sensor array includes a semiconductor substrate and a plurality of pixels disposed on the semiconductor substrate. Each pixel includes a coupling region and a junction region, and a slab waveguide structure disposed on the semiconductor substrate and extending from the coupling region to the region. The slab waveguide includes a confinement layer disposed between a first cladding layer and a second cladding layer. The first cladding and the second cladding each have a refractive index that is lower than a refractive index of the confinement layer. Each pixel also includes a coupling structure disposed in the coupling region and within the slab waveguide. The coupling structure includes two materials having different indices of refraction arranged as a grating defined by a grating period. The junction region comprises a p-n junction in communication with electrical contacts for biasing and collection of carriers resulting from absorption of incident radiation.

Abstract: Methods and systems for detecting at least one chemical species including obtaining a first image from a first electromagnetic radiation detector and obtaining a second image from a second electromagnetic radiation detector. The first image includes a first plurality of pixels and the second image includes a second plurality of pixels, each pixel having an associated intensity value. A first resultant image is generated. The first resultant image includes a plurality of resultant pixels, each pixel having an associated intensity value. One or more regions of interest are determined. The correlation between the first image, the second image, and the first resultant image is determined for the one or more regions of interest using a correlation coefficient algorithm to calculate a first correlation coefficient and a second correlation coefficient. The presence of the chemical species is determined based, at least in part, on the first correlation coefficient and the second correlation coefficient.

Abstract: Apparatus, systems and methods for use in analyzing discrete reactions are provided. The analytical devices of the invention use an array of nanoscale regions (a chip) that has discrete patches, for example, patches of nanoscale regions. In some embodiments an analytical system is provided that has an analysis chip with an array of patches, each of the patches comprising nanoscale regions that emit fluorescent light when illuminated. The system has a two-dimensional (x, y) array of dichroic prisms, each prism comprising a dichroic element that diverts illumination light up in the z dimension of the array to a patch on the analysis chip above it. Each dichroic element transmits fluorescent light emitted by the patch that it illuminates, whereby the emitted light from each patch passes down through each dichroic prism. The analytical system also has a detector below the array of dichroic prisms that detects the transmitted fluorescent light. Such systems are useful for monitoring many analytical reactions at one time including single molecule sequencing reactions.
