Abstract(in English) | Although a computer-generated hologram that is sufficiently optimized has high quality in computer reconstruction, the quality decreases in a real optical reconstruction system. To overcome this issue, we implemented an adaptive scheme that compensates for the spatial properties of the real optical reconstruction system with a liquid-crystal spatial light modulator and feedback control based on estimation of the reconstructed diffraction pattern. We demonstrated holographic femtosecond laser processing with the adaptive optimization, and analyzed the optimization performance. Furthermore, to examine the origin of residual error after the adaptive optimization was performed sufficiently, we also investigated the temporal characteristics of the spatial light modulator. |
