11 November 2014 Study on the resolution of Fresnel incoherent correlation holography
Author Affiliations +
Fresnel incoherent correlation holography (FINCH) is one of the methods for recording digital holograms of 3D samples under incoherent illumination. This method has been successfully applied to white reflective holographic imaging and 3D microscopic imaging. In this article, the processes of optical recording, digital reconstruction and the point spread function of the classic FINCH system are described in detail. The reconstruction images of three letters of “Z”, “W” and “F”, each of which has a different distance from the collimating lens, are simulated. The expression of the resolution of FINCH system has been deduced, which shows that the resolution of the optimal FINCH is beyond the Rayleigh resolution. Effect of the background light on the resolution is analyzed through two groups of contrast experiments when introducing the polarizer in FINCH system and changing phase masks on the SLM.
