Abstract: Systems, tools, and methods are presented for processing a plurality of spectral ranges from an electromagnetic radiation that has been interacted with a fluid. Each spectral range within the plurality corresponds to a property of the fluid or a constituent therein. In one instance, a series of spectral analyzers, each including an integrated computational element coupled to an optical transducer, forms a monolithic structure to receive interacted electromagnetic radiation from the fluid. Each spectral analyzer is configured to process one of the plurality of spectral ranges. The series is ordered so spectral ranges are processed progressively from shortest wavelengths to longest wavelengths as interacted electromagnetic radiation propagates therethrough. Other systems, tools, and methods are presented.

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 of nanoscale regions. The chip mates with a collection device comprising an array of compact lens trains (CLTs) where each of the CLTs corresponds to a single patch of nanoscale regions. Each CLT collects the emitted light from a patch on the chip, collimates the light, performs color separation on the collimated emitted light, and focuses the separated light onto a portion of pixels on the detector below the CLT. Such systems are useful for monitoring many analytical reactions at one time including single molecule sequencing reactions.

Abstract: Snapshot spectral imagers comprise an imaging lens, a dispersed image sensor and a restricted isometry property (RIP) diffuser inserted in the optical path between the source image and the image sensor. The imagers are used to obtain a plurality of spectral images of the source object in different spectral bands in a single shot. In some embodiments, the RIP diffuser is one dimensional. An optional disperser may be added in the optical path, to provide further dispersion at the image sensor. In some embodiments, all imager components except the RIP diffuser may be part of a digital camera, with the RIP diffuser added externally. In some embodiments, the RIP diffuser may be included internally in a digital camera.

Abstract: The present disclosure describes an ultraviolet (UV) sensor configured to detect a target UV spectrum (e.g., UVB spectrum). The UV sensor includes a first photodiode with a first UV spectral response and a second photodiode with a second UV spectral response. A filter layer having a graded spectral response is formed over the second photodiode, and the second UV spectral response is affected by a controlled parameter (e.g., thickness) of the filter layer. The UV sensor further includes a subtraction circuit coupled with the first photodiode and the second photodiode. The subtraction circuit is configured to provide a differential response based on a difference between the first UV spectral response and the second UV spectral response. The controlled parameter of the filter layer can be selected such that the differential response provides a detected spectral response of the target spectrum.
