The overall thrust for development of Night Vision Systems has been to provide equipment which will satisfy the high performance requirements of the modern Army while keeping both acquisition and maintenance cost at the low level necessary to allow high density utilization, This thrust has been pursued by placing emphasis on modular configuration, which allow common use of major. components such as standard, image. tubes, lens systems, and power supplies. Other papers presented during this seminar have already covered, in great detail, image tube and optical assembly. performance. Therefore, I will cover only field applications, present status and development programs.
