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.

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.

A video camera device and system for white light and fluorescence imaging performs imaging for both fluorescence and non-fluorescence light collected from an illuminated scene. A beamsplitter downstream from an optical subsystem separates light a non-fluorescence image into a first imaging channel for and light for a fluorescence image into a second imaging channel. A meniscus lens is positioned downstream from the beamsplitter in one of the first and second imaging channels, and functions to change a magnification such that a magnification of the first image channel is different from a magnification of the second imaging channel. One or more image sensors downstream of the beamsplitter capture the fluorescence and non-fluorescence image light as a fluorescence image and a non-fluorescence image. The fluorescence image has an image size with a smaller area on the sensor or sensors than an image size of the non-fluorescence image.

Hyperspectral imaging methods, devices and systems are described that improve the hyperspectral accuracy, and reduce manufacturing costs, by using two images that enable the recovery of hyperspectral images with high fidelity. One hyperspectral imaging device includes one or more imaging lenses, one or more sensors positioned to receive light associated with an object from the one or more imaging lenses, and a spectral filter. The hyperspectral imaging device is configured to capture a first image produced without using the spectral filer and to capture a second image produced with the spectral filter. The first image and the second image have different spectral contents, and the first and the second images are processed using a trained neural network for producing hyperspectral imaging data associated with the first and second images.
