Abstract

Terahertz imaging can make up the defect of imaging opaque samples in visible light domain. Digital holography is a new technology for extracting full information of the original object. In the paper, the improved angular spectrum (AS) algorithm is coulping the original AS algorithm with direct current (DC) suppression method, apodization and piecewise-nonlinear transformation. The reconstruction characteristics of the algorithm have been studied by numerical analysis and experimental researches. The experimental results validate the application value of the algorithms in improving 2D reconstructed image quality in terahertz Gabor inline digital holography.
