OPTICAL PROJECTION SYSTEM Russian patent published in 2010 - IPC G03B21/00 G02B27/18 H04N5/74 

FIELD: physics.

SUBSTANCE: system has an optical modulator, an optical transfer part, an optical projection part, an aspherical mirror and a reflection shield. The optical transfer part has an inherent part which includes at least one optical element lying on a first optical axis. The optical projection part has an inherent part which includes at least one optical element lying on a second optical axis which is shifted from the first optical axis. The optical transfer part and the optical projection part have a common part which includes at least one reflecting and one refracting optical element. The inherent part of the optical transfer part transmits light beams from the optical modulator to the common part which transmits light beams in the forward direction from the inherent part of the optical transfer part to the reflecting element on which an intermediate image forms, and in the reverse direction from the reflecting element to the inherent part of the optical projection part which guides light beams to the aspherical mirror.

EFFECT: reduced weight and dimensions.
