摘　　要：偏振小孔干涉仪是一种可实用的新型干涉仪。它综合小孔衍射技术、偏振技术和共光路设计为一体,具有条纹对比度可调、抗干扰能力强和非接触检验等优点,可广泛用于各种光学元件及其胶合层的检验。目测精度达1/10λ,计算机条纹处理精度可调。The polarization pinhole interferomenter is a new practical instrument. It synthesizes the techniques of pinhole diffraction, common light path and polarization technique in its design. It has many advantages, such as the fringe contrast adjustable, nondestructive testing, and strong anti-interference ability. The instrument can be used extensively in various optical element testing and their glue layer testing. The accurace of the fringe pattern analysis is controlled by the fringe sample point numbers.
