Paper Abstract

We discuss the application of narrowband holographic filters for aerosense technique including laser radars, communication devices, etc. It is well known that very thick volume holograms both transmission and reflective type being illuminated by light indicate very high angular and spectral selectivity. The variety of sensor require such selection. We report the experimental result of recording of selectors with nanometric bandwidth of spectral selectivity and milliradian bandwidth of angular selectivity recorded in photopolymer with diffusive amplification of about millimeter thickness. We investigated the affect caused by introduction of holographic filter into receiving signal: the influence of filter selectivity property on the spatial frequency distribution of light passed through the atmosphere. We analyzed the possibility to vary the shape of the output power spectral density by means of hologram apodization.
