Abstract
The test system includes an electronic device comprising a camera for forming an image on a detector. A holographic element of the test system and the camera under test of the electronic device are arranged during testing to be placed at a predetermined distance from one another where the holographic element is unfocused in the image field of the camera under test, and the holographic element comprises a holographic test image that is arranged to form a focused image on the detector of the camera operating as desired.
