Abrégé
(EN)
A multi-spectral two-dimensional imaging spectrometer (10) includes a combination of achromatic, well-corrected lenses (14) for imaging a two- dimensional scene on an internal field stop (20). The light emanating from this intermediate image is collimated with another well-corrected lens (24). A spectral separation subassembly (22) that divides the incident light into multiple, identical, and independent arms is placed in the collimated space following the collimating lens (24). The light in each arm is spectrally filtered based on the properties of an interference filter (30) in each arm. An imaging subassembly (32) composed of a well-corrected lens (34) forms contiguous images onto a single two-dimensional detector array (36). The images are identical copies of the original object with each copy having a different spectral component and can be viewed on a standard monitor or alternatively on a computer employing an analog-to-digital conversion device.
