Abstract:
A uniform light generating system for testing an image-sensing device includes a light-generating unit, a light-transmitting unit, a light-diffusing unit, and a lens unit. The light-generating unit has a substrate and a plurality of light-emitting elements electrically disposed on the substrate. The light-transmitting unit has one side communicated with the light-generating unit for receiving and uniformizing light beams projected from the light-emitting elements. The light-diffusing unit has one side disposed on the other side of the light-transmitting unit for receiving and diffusing the light beams that have passed through the light-transmitting unit. The lens unit is disposed on the other side of the light-diffusing unit for transmitting the light beams that have passed through the light-diffusing unit to the image-sensing device.
