ABSTRACT:
Disclosed is a method for automatically determining parallax in a stereoscopic system, comprising the steps of: passing at least two imaging light channels through a moving grating structure; converting the light rays into separate electrical signals after passage through the moving grating structure; differentiating the input signals; multiplying the differentiated signals with the opposite input signal; subtracting the signals obtained by the multiplication from each other to obtain a signal corresponding to parallax. This signal in turn can be utilized to adjust the parallax to zero by actuating optical adjustment means. Also disclosed is the apparatus for carrying out this method.
