摘要
基于阿贝成像理论对数字全息波面重建系统进行研究.结果表明,利用成像系统对物光场进行变换,可以让物光场的高频角谱分量到达电荷耦合器件(CCD)探测器.为研究重建物光场质量,导出了CCD在光学系统后任意位置波面重建的计算公式,研究了物光通过傍轴光学系统到达CCD时波面重建系统的脉冲响应.理论及实验研究表明,将CCD平面置于物光场像平面附近可以对物光场进行高质量重建.
The system of digital holographic wave-front reconstruction is studied based on Abbe imaging principle. The results show that the high-frequency angular spectral component of object light can arrive at charge-coupled device（CCD） detector through using imaging system to transform the object light field. To evaluate the quality of reconstructed object light field, the calculation formula to reconstruct wave-front at arbitrary position after the optical system on the CCD is derived, and pulse response of wave- front reconstruction system is researched when the object light arrives at CCD through paraxial optical system. Theoretical and experimental researches show that the object light field can be reconstructed with high quality when the CCD plane is close to the image surface.
