    Abstract: A spectral camera having an objective lens, an array of lenses for producing optical copies of segments of the image, an array of filters for the different optical channels and having an interleaved spatial pattern, and a sensor array to detect the copies of the image segments is disclosed. Further, 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.

    Abstract: A filter wheel and a spectrometer including the filter wheel are disclosed. The filter wheel has a first support structure on which a first plurality of filters are mounted and a second support structure on which at least one filter is provided. A radiation source generates a radiation beam, and a beam splitter splits the radiation beam into a first detection path and a second detection path. The first plurality of filters are selectively movable into the first detection path. The at least one filter on the second support structure is arranged to be disposed in the second detection path. The spectrometer includes a first radiation detector that detects radiation that passes through the selected filter in the first detection path, and a second radiation detector that detects radiation passing through the filter in the second detection path.

    Abstract: A method of using multivariate optical computing in real-time to collect instantaneous data about a process stream includes installing an optical analysis system proximate a process line, the process line being configured to move a material past a window of the optical analysis system; illuminating a portion of the material with a light from the optical analysis system; directing the light carrying information about the portion through at least one multivariate optical element in the optical analysis system to produce an instantaneous measurement result about the portion; and continuously averaging the instantaneous measurement result over a period of time to determine an overall measurement signal of the material.
