Abstract: The radiation to be analyzed is sent onto an interference filter which selects different portions of the radiation spectrum in correspondence with different incidence angles. The intensity values of the radiation outgoing from the element are stored by a measuring and data processing unit which processes such values with the transfer function of the element to obtain the information on the spectrum.

Abstract: This invention integrates a spectrometer capability with the basic imagery function of facsimile cameras without significantly increasing mechanical or optical complexity, or interfering with the imaging function. The invention consists of a group of photodetectors arranged in a linear array in the focal plane of the fascimile camera with a separate narrow band interference filter centered over each photodetector. The interference filter photodetector array is on a line in the focal plane of the facsimile camera along the direction of image motion due to the rotation of the facsimile camera''s vertical mirror. As the image of the picture element of interest travels down the interference filter photodetector array, the photodetector outputs are synchronously selected and sampled to provide spectral information on the single picture element. The selection of the proper photodetector and data sampling is controlled by information derived from the servo system controlling the vertical mirror rotation.

Abstract: The invention discloses a Trace Microanalysis Microscope System for high throughput screening. A multimodal imaging sensor arrangement acquires color, multispectral, hyperspectral and multi-directional polarized imaging, independently and in combinations thereof. In one aspect of this disclosure, the multimodal acquisition is combined with a plurality of sample illumination modes, further expanding the dimensionality of the generated data. In another aspect of this invention, machine learning-based methods combining and comparing a-priori data with the acquired multimodal data space, provide unique identifiers for the composition of the analyzed target objects. In yet another aspect of this invention, projection mapping of the identified compositional features navigates secondary sampling for subsequent analyses.

Abstract: A sensor system has a plurality of optical sensors configured in an array on an integrated circuit and a lens system located proximal to a top surface of the array, where the intersection of the optical axis of the lens system with the plurality of optical sensors defines a reference point for light passing through the lens system.

In the sensor system each optical filter of the plurality of optical filters is configured to pass light in a different wavelength range, with at least some sets of optical filters configured to provide a center wavelength that is higher than a center wavelength of a set of optical filters at the reference point. An interface is provided for receiving output signal representative of received light from the optical sensors and to output signal from the plurality of optical sensors, with the output signal being representative of received light from the plurality of optical sensors and a spectral response is determined for each set of optical sensors associated with a set of optical filters.
