Abstract: A multi-spectral optical sensor comprises a plurality of apertures, a plurality of lens arrangements, a plurality of optical filters and a monolithic semiconductor chip defining a plurality of sub-arrays of optical detector regions, each sub-array comprising the same number and relative spatial arrangement of optical detector regions and the optical detector regions of each sub-array being arranged on a predetermined pitch in a direction parallel to a surface of the of the semiconductor chip. The multi-spectral optical sensor is configured so that light from a scene incident on any one of the apertures along any given direction of incidence is transmitted through the corresponding lens arrangement and the corresponding optical filter to the corresponding sub-array of optical detector regions so as to form an out-of-focus image at a plane of the optical detector regions of the corresponding sub-array of optical detector regions.

Abstract: Systems and methods for hyperspectral and multispectral imaging are disclosed. A system includes a lens and an imaging device having a plurality of pixel sensors. A focus corrector is located within the optical path to refract at least a portion of the incoming light and change the focusing distance of specific wavelengths of light to converge at a focal plane. The focus corrector is selected based upon the imaging system to reduce an overall measure of deviation between a focal length curve for the lens and a focus position curve for pixel sensors to produce focused imaging data for a broad spectrum of light, including beyond the visible range.

Abstract: Devices and methods of the present technology utilize wavelength-dependent transmittance of 2D materials to identify the wavelength of an electromagnetic radiation. A wide range of 2D materials can be used, making possible the use of the technology over a large portion of the electromagnetic spectrum, from gamma rays to the far infrared. When combined with appropriate algorithms and artificial intelligence, the technology can identify the wavelength of one or more monochromatic sources, or can identify color through the use of a training set. When applied in an array format, the technology can provide color imaging or spectral imaging using different regions of the electromagnetic spectrum.

Abstract: A multispectral sensor array can include a combination of ranging sensor channels (e.g., LIDAR sensor channels) and ambient-light sensor channels tuned to detect ambient light having a channel-specific property (e.g., color). The sensor channels can be arranged and spaced to provide multispectral images of a field of view in which the multispectral images from different sensors are inherently aligned with each other to define an array of multispectral image pixels. Various optical elements can be provided to facilitate imaging operations. Light ranging/imaging systems incorporating multispectral sensor arrays can operate in rotating and/or static modes.

Abstract: The present technology provides devices and methods to determine the spectrum or other spectral characteristic, such as color, of a beam of light or other electromagnetic radiation. The beam of light or other electromagnetic radiation is modified without dispersion by broadband transmissive windows and then transmitted onto a detector. Signals from the detector are measured from a training set of radiation having known spectra and used to train the device, after which the device can estimate the spectrum or color of an unknown light or other electromagnetic radiation with exceptionally high accuracy.
