Abstract: A multi-telescope imaging system includes a first telescope and a second telescope, each telescope having an input line of sight, a ray path that is incident upon a focal surface imaging location at a non-normal angle of incidence, and a shutter lying on the ray path. A single common sensor lies at the focal surface imaging location, such that the first-telescope ray path and the second-telescope ray path are alternatingly incident upon the same focal surface imaging location of the sensor. A shutter controller alternatingly opens and closes the two shutters, so that the sensor alternatingly views the scenes imaged by the two telescopes.

Abstract: An imaging spectrometer includes an all-reflective objective module that receives an image input and produces an objective module output at an exit slit, and an all-reflective collimating-and-imaging module that receives the objective module output as an objective-end input and produces a collimating-end output, wherein the collimating-and-imaging module comprises a reflective triplet. A dispersive element receives the collimating-end output and produces a dispersive-end input into the collimating-and-imaging module that is reflected through the collimating-and-imaging module to produce a spectral-image-end output. An imaging detector receives the spectral-image-end output of the collimating-and-imaging module. The objective module may be a three-mirror anastigmat having an integral corrector mirror therein, or an all-reflective, relayed optical system comprising a set of five powered mirrors whose powers sum to substantially zero. The collimating-and-imaging module may be optimized to minimize spectral smile.

An all-reflective switching structure is operable to direct a light beam through the afocal module and the imaging module. A first position of the switching structure directs the light beam to enter the first optical end of the afocal module and exit the second optical end of the afocal module, and thereafter to enter the input optical end of the imaging module and to exit the output optical end of the imaging module. A second position of the switching structure directs the light beam to enter the second optical end of the afocal module and to exit the first optical end of the afocal module, and thereafter to enter the input optical end of the imaging module and to exit the output optical end of the imaging module. A third position of the switching structure directs the light beam to enter the input optical end of the imaging module and to exit the output optical end of the imaging module, so that the light beam completely bypasses the afocal module.
