Abstract
A method and apparatus for aligning image sensors with an optical system in an optical apparatus utilizing photosensors incorporated in the image sensors with high precision. The reference light beams are focused on the image sensors each having a specified photosensor for receiving a respective light beam. Signal outputs from the specified photosensors of the image sensors are measured. The position of the image sensors is adjusted relative to the position of the optical system in response to the measured signal outputs.
