Abstract
An optical wavefront testing system includes a light source, an image capturing unit and a processing unit. The image capturing unit includes a lens array and a sensor module that is configured to detect light rays passing through an optical element and the lens array. The processing unit controls the sensor module to detect the light rays under a plurality exposure conditions for generating a plurality of images each including a plurality of light spots, obtains a plurality of light spot datasets corresponding to the light spots and each including a plurality of pixel coordinate sets and a plurality of pixel values, and obtains wavefront information associated with the light spots based on the light spot datasets of at least two of the images.
