Paper Abstract

Cleaving-etch method was presented for improving relief modulation resolution in gelatin. The principle of the method was introduced. Using the cleaving-etch method, a sine relief grating was obtained with 200 lines/mm spatial frequency and 0.4 micrometers relief depth. Comparison between enzyme-etching-imaging method and the cleaving-etch method was given and the reason why resolution of the latter much higher than the former was presented.
