ABSTRACT:
An imaging apparatus for permitting night vision training by simulating night vision viewing during daylight operation. A cylindrical imaging device includes an objective lens and an ocular lens. Light from the objective lens passes through a filter and is inverter by a fiber optic inverter. A pair of liquid crystals receive the inverted image and pass the same to the ocular lens for viewing by the user. A plurality of lamps are positioned for impinging light on the second liquid crystal under electronic control. The pair of liquid crystals are controlled electronically for simulating night vision photomultiplier viewing. A pair of such imaging tubes are mounted in a training helmet together with under-goggle viewing areas and peripheral viewing areas in which liquid crystals are separately placed and are separately controllable in accordance with sensed light levels. An instructor pilot uses a microprocessor based controller for controlling each of the six liquid crystals.
