    Research output: Chapter in Book/Report/Conference proceedingConference contribution


    An inverse tangential phase mask (ITPM) is potentially effective for extending the depth of field in the wavefront coding method. However, its characteristics have not been reported in detail. In this study, we obtained the ITPM profile function and confirmed that the optimized ITPM is more effective than a cubic phase mask (CPM) in several respects.
