Abstract: An optical inspection system includes a brightness inspection module for inspecting the brightness of a light emitting element, an integrated inspection module for inspecting the near field optical characteristic and the beam quality factor of the light emitting element, and a far field inspection module for inspecting the far field optical characteristic of the light emitting element. As a result, the optical inspection system is space-saving and capable of reducing the distance and time of the movement of the device under test.

Abstract: A light emitting element detecting method includes the steps of generating a first control signal to open a shutter of an image capturing device which captures an image toward a light outlet of a light emitting element, generating a pulse signal to light up the light emitting element, generating a second control signal to close the shutter of the image capturing device and obtaining a detection image, and determining the light emitting status of the light outlet of the light emitting element according to the detection image. As a result, the present invention can accurately detect whether the light outlet of the light emitting element has the problem of emitting no light or flashing.
