The success of the U.S. Army's Night Vision Program at Fort Belvoir, VA was significantly influenced by the evolution and timely culmination ofVisionics technologywhichwasinitiatedbyMr.JohnJohnson. In dictate 1950's,Visionics technology started with concern for Near hifrared (NIR) and Image Intensifier (II) Night Vision developmentt It resulted in the Johnson Criteria which coupled system physical charseteristics to visual performance by using resolution of line pairs ross the minimum dimension of a target This led to developmentofimageevaluation proceduresandstandardizedlaboratory testing. LatertheVisionicsteamaddressedtheFarlnfrared(FIR) system performance and developed a sexies ofFLIR Performance Models The Visionics' Static Performance Model computercode was acce and proliferated widely by the mid-70's. Visionics moved from static viewing to address the problems of search effectiveness. Then came more workon target signatures and the consideration oftheeffects offog,rain, snow, artillery barrages, and realistic battlefield condtionsonsystempeancemordertoassuretheutihityoffieldedequipments foralltheatersofinterest Thegeneraluseofthevarious Visionics models and methodology throughout Government and Industry is recognition of the contributions made by Mr. John Johnson and his Visionics staff.
