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.
