摘要

In this paper, we use Mach-Zehnder interferometry (MZI) technique to enhance image objects resolution. We take sample's correlation characteristics over Walsh-Hadamard (WH)-coded spatial-light modulator (SLM) to boost the image resolution of sample objects detection. Comparing the spectral interferences with and without WH-coded SLM, we get more contrast difference on the correlation magnitudes. Through with computer simulations, we find that the interference correlations under coded-SLM have a contrast ratio of 2.0 which is larger than the contrast ratio of 1.49 for sample measurement without SLM coding. The enhancement of image objects resolution is thus assured in the paper.
