Abstract
A method for aligning an image sensor relative to a lens module, the method comprising the steps of: receiving a test image along a first optical path with the lens module and projecting the test image along a second optical path transverse to the first optical path with the lens module; manipulating an orientation of the lens module with respect to the image sensor to project the test image along the second optical path onto the image sensor; using the test image received by the image sensor along the second optical path to determine a corrected orientation of the lens module with respect to the image sensor, so as to align the lens module with respect to the image sensor; and thereafter fixing the aligned lens module to the image sensor.
