由于其高度的灵活性以及光学系统的高速性和实时性，计算全息在模式识别、光学计算等信息光学领域得到广泛应用，但精度的提高成为很多应用实用化的关键。根据罗曼Ⅲ型编码理论，设计制作了计算全息图并在实验中成功实现光学再现。系统论述了此编码法设计计算全息图产生误差的原因，特别对散斑噪声、编码噪声和光学系统误差作了详细分析，并指明了如何降低计算全息编码误差及提高再现像质量的途径，使其更好、更广泛地在信息光学领域得以应用
- Abstract:
-
The computer- generated hologram（CGH） is applied extensively in information optics, such as pattern recognition, optics computing and so on, owing to its flexibility, high speed, real time. But it is a key to improve precision in many applications. An optically reconstructed image was successfully obtained by CGH which was designed and manufactured based on Lohmann Ⅲ coding theory. Reasons for error in the reconstructed image are systematically analyzed. Particularly speckle noise, coding noise and optics system noise are analyzed in detail. In order to spread its application in information optics fields, methods on how to reduce CGH coding errors and improve CGH quality are also given
