Abstract

Narrow bandwidth is one of the major disadvantages of the computer generated holographic (CGH) spatial filters (SF). Increase of the bandwidth obtained by D/A convertion, i.e. holographic copying of CGHSF to analog HSF with external refererence beam is presented in this work. Relatively large angle between object beam from CGHSF and the reference gives the large "carrier spatial frequency" on the analog HSF, so the object processed by the filter converted this way may have space-bandwidth product (SBWP) much larger then CGHSF itself. The qualitative analysis and the experimental results are presented.
