Real-time two-dimensional holographic imaging by using an electron-beam-addressed spatial light modulator

Not Accessible

Your library or personal account may give you access

Abstract

A real-time electron-beam-addressed spatial light modulator-based holographic imaging system has recently been proposed. We present results of two-dimensional holographic imaging and further demonstrate that the proposed system can be readily adaptable to automation by using digital computers for robust holographic imaging. Specifically, by nonlinear processing of a digitally stored hologram, fringe contrast enhancement has been achieved.
