Abstract
In incoherent digital holography, the reconstructed image is strongly affected by noise on the interference fringes. We investigated a means of noise reduction that reduces the degradation of the high spatial frequency components in the reconstructed image. In particular, we applied a 5x5 tap digital filter to the interference fringes. By optimizing the filter, the noise level could be made uniform and the contrast at high spatial frequencies could be made twice that of using a mean filter. We found that a digital filter can improve the quality of reconstructed images in incoherent digital holography.
