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 grating structure; subtracting one of the electrical signals from the other to produce a signal difference; differentiating one of the electrical signals to produce a differentiated signal; multiplying the signal difference by the differentiated signal to produce a first multiplied signal; and controlling the orientation of one of the imaging light rays in response to the multiplied signal. Also disclosed is our apparatus for carrying out this method.
