Paper Abstract

Work carried out at PPE over the last ten years has resulted in the development of four head-mounted passive night vision goggles of unity magnification. Considered in relation to each other, these systems illustrate the technical progression from the oriainal sight, a twin image intensifier tube device that employed conventional optics, through a series of three single tube goggles of decreasing complexity, weight and cost. The MkI and MkII single tube devices, of beamsplitter/relay lens and collimator/multireflector design respectively, required precise manufacture: the later of the two designs, however,was both simpler in construction and more advanced in technical specification than the earlier. The concept of the MkIII single tube goggle was influenced by the lower relative cost of current intensifier tubes and resulted in a lens design that can be fabricated in its entirety in optical plastics. Compared with the original two tube goggle, the final system has a similar technical specification but is much cheaper and less than half the weight. The paper describes the optical design philosophy behind each goggle and the evolution of each subsequent stage.
