Beschreibung
Zusammenfassung:	Provided are methods for active alignment of an optical assembly with intrinsic calibration. Some methods described include performing a first active alignment using a multi-collimator assembly, determining a principal point of the camera assembly using a diffractive optical element (DOE) intrinsic calibration module, and adjusting the relative position of one or more of the lens and the image sensor to align the principal point of the camera assembly with an image center of the image sensor and to perform a second active alignment. Systems and computer program products are also provided.
