Variable spatial resolution focal plane

摘要

The light from a telescope impinges upon a tilted image plane. The plane primarily includes a mirror having a high spatial resolution focal plane imbedded therein. The mirror reflects image light rays to a lower spatial resolution focal plane. The detectors from the high spatial resolution focal plane and lower spatial resolution focal plane are connected to a computer which is capable of generating a display of the lower spatial resolution focal plane showing a general background scene as well as a superimposed display of the small high spatial resolution focal plane showing an enhanced image of a desired small area. The result is the minimization of the number of detectors that must be employed to obtain a satisfactory high spatial resolution area of interest with attendant minimization of computer processing time.
