Abstract
A light energy testing device includes a light source emitting parallel light, a Fresnel lens concentrating the parallel light, a fiber array consisting of a plurality of optical fibers, and an energy detecting device. Each fiber includes a light incident and emitting surface. The light incident surfaces are coplanar to define a light receiving surface. The light emitting surfaces cooperatively define a light transmitting surface. The energy detecting device includes a plurality of sensor units optically coupled with the light transmitting surface and a testing device connected to the sensor units. The parallel light is focused by the Fresnel lens to irradiate the light receiving surface. The sensor units generate energy signals according to the light from the light transmitting surface. The energy detecting device calculates a light energy distribution according to the energy signals.
