Abstract:Terahertz (THz) digital holography is a combination of THz technology and digital holography which has drawn wide attention. Exact measurements of real recording distances in terahertz (THz) digital holography are important. Autofocusing experimental researches have been conducted based on the holograms in THz off-axis digital holography. Five criterion functions are utilized in this paper. Autofocusing performance of these criterion functions has been analyzed and compared by changing the numbers of the super… Show more
