Multiplex Wide Field Optics (MWFO)

Recent studies have demonstrated that user error can be reduced when using night vision goggle if the user's field of view and resolution is increased. Efforts to provide a wide viewing field with traditional approaches have led to complex and expensive wide angle or multiple lens/tube designs making them impractical for field applications. There is a need for an approach which can provide an alternative solution to the problem. Diffraction LTD proposes an innovative approach which will use Liquid Crystal Switches (LCS) to achieve a wide angle single lens and tube night vision goggle. The proposed approach will time multiplex three views through a single imaging lens and intensifier tube. This will be achieved by using an innovative electronically addressable broad band non-polarized splitter which will be placed in front of the primary imaging lens directing three images from different viewpoints in a time sequence (on axis) through a single lens and intensifier tube. The images are sent (one at a time) through the lens and tube and re-assembled to the appropriate position to the eyepiece at a high repetition rate providing a multiplexed wide field image to the user.
