Feasibility Prototype Cyclops Eyepiece, Wide Angle Cyclops Eyepieces, Dual Channel and Cyclops Mini-Goggle Systems, Third Generation Systems

摘要

A major portion of this work was the development of an innovative eyepiece system which permits the use of a single image intensifier tube per night vision goggle. This eyepiece, referred to as a cyclops eyepiece, was to provide two-eye viewing of a single tube output. The development goals were to obtain operation performance equivalent to the standard dual channel systems currently utilized by the United States Army personnel. Investigations were carried from an initial 18mm, 40 deg field of view feasibility model through a 12mm format system, wide angle systems in 18mm and 25mm formats to a final 18mm format 40 deg field of view cyclops eyepiece reflecting all of the experience gained. Other areas examined under these contracts, and discussed herein, were 12mm dual channel goggles, and high performance objective lens for second and third generation intensifier tubes. A comprehensive set of conclusions based upon all of the work efforts is included at the end of the report, accompanied by recommendations for future studies.
