Abstract: A multiple field of view dual band optical device with integrated calibration source is disclosed. Such an optical device is modular, and has a rotating electro-mechanical “tumbler” which houses two orthogonal Galilean afocal optical assemblies as well as at least one uniform temperature source. This modular device is intended to be inserted in front of a camera system which already has an imager optical assembly mated to a detector focal plane array. The disclosed modular device thus serves the purpose of providing to an existing dual-band camera imager up to four new optical fields of view as well as an integral calibration source, all of which can be electro-mechanically selected for viewing by a host camera imager.

Abstract: A focal plane array dual processing system and technique utilizes a single ocal plane array to provide scene imagery and temporal processing of a sub-region of the scene. Resultant data from a row by column focal plane array detector elements is processed for imaging and image processing by an image processor. A smaller data subset from a row by column subset of the focal plane array with resultant spatial data subset is temporally processed by a temporal processor. The data and data subset which is multiplexed, digitized and formatted as raster-formatted raw data vector format is addressed for image and temporal processing by a data buffer integrator.
