Paper Abstract

The authors report experimental results of optical edge enhancement using a modified filter, i.e. hybrid raised-cosine spiral phase filter (SPF). This filter is capable to produce optimized optical image processing results. Comparing with conventional SPF, the proposed filter is able to suppress redundant noise for better contrast and resolution of the edge-enhanced image with improved efficiency. The proposed filtering process is demonstrated using off-axis holograms displayed on a spatial light modulator (SLM) and can be readily incorporated with conventional microscopic system.
