Abstract
A method for determining a tilt of an image sensor surface plane in a camera in relation to a lens reference plane of the camera includes sending light onto the image sensor, receiving light reflected from the image sensor, identifying an interference pattern in the reflected light, identifying a feature of the interference pattern, and determining the tilt of the image sensor surface plane based on a position of the feature identified in the interference pattern.
