Abstract
Terahertz digital holography, which can be used in nondestructive testing and other fields, is the effective combination of terahertz imaging and digital holography. The measurement accuracy may be influenced by the low energy of terahertz source and other factors; therefore it is very important to study denoising algorithms of terahertz digital holographic images. In this paper, optimally weighted bilateral filter (WBF) is applied in the preprocessing of guide image acquired by guided bilateral filter (GBF). This method can eliminate the noise in terahertz digital holography reconstructed image. We compare this algorithm with the original GBF with iterative reweighted least squares algorithm (IRLS). The experimental results show that the preprocessing method is better than the original algorithm.
