FIELD: physics. ^ SUBSTANCE: projective optical system contains the first optical part, second optical part, third optical part and rejecting element, each aforesaid optical part being furnished with an appropriate set of optical elements. Note here that the aforesaid third optical part additionally incorporates at least one light source and is arranged to form a beam of light and to direct it to the said rejecting element designed to direct the beam of light generated by the third optical part onto the second optical part which contains image formation means and is designed to direct the beam of light onto the first optical part for it to project the said beam of light. ^ EFFECT: ease of manufacture, reduces sizes, simpler design and shifted image projection. ^ 9 cl, 3 dwg |
