    Abstract: Light filter apparatus for receiving a light beam (25) having wavelengths in a selected band and for dispersing the light into a plurality of rays (30), with each ray having a different wavelength for which the intensity peaks. The peak wavelength varies approximately continuously with displacement of spatial position in a chosen direction along the filter's light-receiving plane. In one embodiment, the filter is a modified etalon structure having at least two reflecting surfaces whose separation distance is not constant but increases or decreases monotonically with distance in a chosen direction in a light-receiving plane of the etalon. Each of these two reflecting surfaces (26,27) may be planar or non-planar but continuous, or may have a step or staircase configuration. This structure may operate using transmitted light or reflected light. In a second embodiment, an edge filter combination is used to produce a narrow band of transmitted or reflected light having a variable central wavelength that varies with position along the chosen direction. In a third embodiment, a multi-layer thin film structure is used to provide a narrow band of transmitted or reflected light having a variable central wavelength. The filter may be combined with a one-dimensional or two-dimensional array of photosensor elements, which array may be linear, circular or generally curvilinear, one such element receiving a group of adjacent light rays of similar peak wavelength, to provide a plurality of different wavelength readings on an incident light beam for spectrophotometry or colorimetry analysis.

    Abstract: A spectral camera has an objective lens (10), an array of lenses (25) for producing optical copies of segments of the image, an array of filters (30) for the different optical channels and having an interleaved spatial pattern and a sensor array to detect the copies of the image segments. Detected segment copies of spatially adjacent optical channels have different passbands and represent overlapping segments of the image, and detected segment copies of the same passband on spatially non-adjacent optical channels represent adjacent segments of the image which fit together. Having segments of the image copied can help enable better optical quality for a given cost. Having an interleaved pattern of the filter bands with overlapping segments enables each point of the image to be sensed at different bands to obtain the spectral output for many bands simultaneously to provide better temporal resolution.
