| After introducing the existing measuring technique, the intensity distribution measuring technique of small light spot with nanometer resolution is investigate deeply based on requirements of nanometer resolution testing. Intensity distribution measuring system of small light spot was designed and constructed. By using intensity distribution measuring system which conducts light field intensity distribution detection experiment under low numerical aperture, a good surface of intensity distribution is obtained. The experimental results show that the intensity distribution measuring system has advantages of high reliability, good stability, and user-friendly interface. |
