Abstract :
As a fast, simple and robust method for the field of non-destruction and non-contact testing and recording, digital holography has made great progress in recent years. Digital holographic reconstruction, an important part of digital holography, is also rapidly developing. In this paper, a new digital holographic reconstruction method is described, which is based on electrical addressed liquid crystal display (EALCD) and charged coupled device (CCD). Some properties of liquid crystal have been given in detail. Due to the digital devices mentioned above, it is not only convenient to improve the quality of the reconstructed image, also it has many advantages. On the basis of theory analysis, the new method is described in detail and has been carried out by optical experiment successfully.
