  • 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.

Abstract: 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.
