With a rapid growth in modern optical test and measurement in recent years, Optical interference technique has become very important for precise and hyper-precise measurement and nano-detection. As one of the most popular technologies, polarization measurement (phase measurement) is more and more widely used recently.

Phase measurement records the intensity of the light under specific angles. It is widely used based on the accuracy. However, manual operation on the optical devices will cause large measurement error. It’s better to do the measurementby devices itself.

In this thesis, we have developed a software system which can control the rotator rotating, the camera grabbing images and calculating to get the final phase image automatically, by using LabVIEW which is a platform and development environment for a visual programming language from National Instruments.

It gains the detailed data which lays the foundation for further researches on image analysis, such as remove fringes and only hold the surface image.
