18. DESCRIPTION OF INTELLIGENCE REQUIREMENT AND DETAILED TECHNICAL DESCRIPTION OF PROJECT (Continue on addi-
tional page if required)
Image forming optical systems degrade the images they produce, and since these
degradation
di
s are
fficult to compensate for, there is usually a resultant loss
in information content
Th
.
e purpose of this study is to determine if coherent,
complex spatial filtering can achieve a useful degree of ima
ge restoration. More
specifically, the problem shall be investigated using coherent
processing to
compensate for the amplitude and phase distortion of spatial frequencies introduce:i '

by the optical image-forming system. It will require construction of spatial
frequency filters in which both amplitude and phase are controlled. Since
this contractor has previously established an ability to achieve such filter
fabrication, the major concentration will be on determining if existing
techniques provide a, useful tool to attack this restoration problem.
