technical field
[0001] The invention relates to the technical field of optical testing, in particular to a photosensitive module testing device. Background technique
[0002] With the development of multimedia technology and electronic technology, photosensitive modules are widely used in mobile phones, computers, door locks and other electronic products. The demand for various types of photosensitive modules is increasing, and certain test indicators must be met accordingly. For example, the 3D structured light receiving end Rx module or RGB lens module in the photosensitive module mainly tests the sharpness, optical center, dirt and dead pixels and other test items.
[0003] Among the above test items, a uniform light source (uniformity > 95%) is required for the test of the optical center and dirt, and a blackboard (black non-reflective material) is required for the dead pixel test. During the test, moving the uniform light source directly above the photosensitive mod...
