Abstract
To align an optical module to an image sensor module comprising at least an image sensor, a test image is received with a reference optical element along a first reference optical path, before reflecting the test image along a second reference optical path with the reference optical element towards the image sensor module. An alignment orientation of the image sensor module is first corrected with respect to the reference optical element in order to receive the test image over the second reference optical path onto the image sensor. The reference optical element is subsequently replaced with the optical module. Next, an orientation of the optical module is manipulated such that the second optical path coincides with the second reference optical path so as to optically align the optical module with the image sensor module, before the optical module is finally attached to the image sensor module.
