Abstract: A multi-aperture imaging system comprising a first camera with a first sensor that captures a first image and a second camera with a second sensor that captures a second image, the two cameras having either identical or different FOVs. The first sensor may have a standard color filter array (CFA) covering one sensor section and a non-standard color CFA covering another. The second sensor may have either Clear or standard CFA covered sections. Either image may be chosen to be a primary or an auxiliary image, based on a zoom factor. An output image with a point of view determined by the primary image is obtained by registering the auxiliary image to the primary image.

Abstract: An image processing method includes: an image pickup step of picking up an RGB image of a target object to be picked up, and picking up a spectroscopic image of the target object in a predetermined wavelength range and thus acquiring spectroscopic information peculiar to the target object in the wavelength range; and a display step of displaying a complemented image complemented by superimposing the spectroscopic information on the RGB image.

Abstract: Various embodiments disclosed herein describe a divided-aperture infrared spectral imaging (DAISI) system that is adapted to acquire multiple IR images of a scene with a single-shot (also referred to as a snapshot). The plurality of acquired images having different wavelength compositions that are obtained generally simultaneously. The system includes at least two optical channels that are spatially and spectrally different from one another. Each of the at least two optical channels are configured to transfer IR radiation incident on the optical system towards an optical FPA unit comprising at least two detector arrays disposed in the focal plane of two corresponding focusing lenses. The system further comprises at least one temperature reference source or surface that is used to dynamically calibrate the two detector arrays and compensate for a temperature difference between the two detector arrays.

Abstract: A divided-aperture infrared spectral imaging (DAISI) system that is structured to provide identification of target chemical content in a single imaging shot based on spectrally-multiplexed operation. The system is devoid of spectral scanning acquisition of infrared (IR) spectral signatures of target content with an IR detector and does not require content.

Abstract: Systems and methods for determining one or more properties of a sample are disclosed. The systems and methods disclosed can be capable of measuring along multiple locations and can reimage and resolve multiple optical paths within the sample. The system can be configured with one-layer or two-layers of optics suitable for a compact system. The optics can be simplified to reduce the number and complexity of the coated optical surfaces, et al. on effects, manufacturing tolerance stack-up problems, and interference-based spectroscopic errors. The size, number, and placement of the optics can enable multiple simultaneous or non-simultaneous measurements at various locations across and within the sample. Moreover, the systems can be configured with an optical spacer window located between the sample and the optics, and methods to account for changes in optical paths due to inclusion of the optical spacer window are disclosed.

Abstract: A compact spectrometer includes an excitation light source configured to generate excitation light and arranged to illuminate a spot on a sample. A dispersive element includes at least one movable component and spatially separates output light emanating from the sample in response to the excitation light into a plurality of different wavelength bands. A moveable component of the dispersive element causes the plurality of different wavelength bands of the output light to be scanned across a detector. The detector includes at least one light sensor that senses the wavelength bands of the output light and generates an output electrical signal in response to the sensed output light.

Abstract: A small scale and low cost spectral sensing system designed primarily for multi-component fluids that provides a compact, low cost platform for analyzers or chemical sensors with limited number of optical and mechanical components featuring a light source, an optical interface with the sample, and a custom detector (multi-element). A single detector element has a specific wavelength, defined by a filter that can be used to select and measure specific chemical compounds. Multiple detector elements are combined to create a multi-channel detector capable of measuring a broad range of wavelengths from ultraviolet (UV) to near and mid-infrared wavelengths. The fabricated sensor can be configured for almost any class of material including gases, vapors, and liquids, with extension to solids. This is linked to the use of the custom detectors featuring filters tailored to specific substances in a broad spectral range from the UV to infrared.
