Abstract: A device for projecting pictures on a screen comprising an electro-optical plate the birefringence of which is controlled by means of an electric charge pattern. In order to prevent that the phase shift of the polarized light is influenced in an undesired manner by the projection objective, namely as a result of temperature influences, the projection objective consists of two parts. The first part is situated between the polarizer/analyser and the electro-optical plate, experiences little influence of temperature variations and determines the power of the objective. The second part is situated between the polarizer/analyser and the screen and mainly corrects for the optical errors of the objective.

Abstract: A sighting device equipped with two optical systems which each comprise an optical modulator and a lens and the optical axes of which intersect at an acute angle and with a radiation-sensitive detector is described. It is shown that by inserting auxiliary radiation sources between the lenses of the optical systems and the radiation-sensitive detector and by using the lenses as catadioptric systems for imaging the auxiliary radiation sources asymmetrical errors can be eliminated.
