Paper Abstract

Several filter algorithms are developed for the purpose of modifying the transmissivity of many matched filters multiplexed onto one hologram. Each algorithm optimizes, or approximately optimizes, a specified performance metric. Four pages of images are multiplexed onto a thin hologram, each page having nine binary images. Computer simulation indicates that some algorithms operate over a wide range of obscurations (down to about 5% of the original image), while others have restricted operating ranges. This process has application to both associative memories and correlation. Two new optical schemes are also proposed that can implement two of these modification filters.
