Character measurement of fiber optic image device using CCD camera

Aim at the requirement of researching new optical devices (fiber optic taper, fiber optic faceplate and fiber optic inverter) a new method for testing the parameters of fiber optic imaging devices featuring a single integral sphere and a CCD camera is put forward. Compared with the method of two integral spheres with photoelectric detector, this method features simply structure, wealth information and fast testing operation. It can realize the measurement of many parameters such as total or partial transmittances, center-edge transmittances relative errors, resolution target, and pincushion and barrel distortions by processing the CCD images of those devices. The testing principle is analyzed and proved feasible by the experiment.
