Abstract:
1. A compact optical module configured for coupling with an image sensor component of an auto focus digital camera module, the compact optical module comprising: an optical train comprising multiple lenses including at least one movable lens; a housing configured to contain the optical train and couple with an image sensor component; a MEMS actuator configured to move the at least one movable lens along an optical path to focus a subject onto an image sensor of the image sensor component that is disposed at a focal plane of the optical train and that is coupled to a printed circuit to carry electronic signals that include digital images captured by the image sensor; an alignment compensation component configured to program a processor to generate alignment compensation signals that are configured to position and align the at least one movable lens based on a specific focus distance and a camera module orientation and nonlinear displacement property of the at least one movable lens; and a pair of lens actuator control pads configured to couple to the printed circuit for receiving lens actuator control signals including said alignment compensation signals.
