Abstract
Image-intensifying glassesthat are suitable for certain commercial and entertainment applications by virtue of their light weight, small size, and economical production, compared to certain other night vision products. In one disclosed embodiment, input light passes through two Amici prismsandand a field-flattening lensto reach an image intensifier. The intensified image it produces is reflected off a first folding mirror, passes through a lens, reflects off a curved mirror, and passes back through the lensthe other way. The intensified image then passes through two additional, non-doublet lensesand, between which an intermediate image exists. The intensified image then reflects off the 'lens,' or visor, of the glasses and proceeds to the pupil of eyeof the wearer. Alternative embodiments use a helmet visor, mirror, or other (at least partially) reflective surface for the final reflection.
