Abstract

It is well known that dichromated gelatin (DCG) is one of the best recording media for the fabrication of holographic optical elements (HOEs). It has been used to make holographic interconnections position-tunable holographic filters and real-time multichannel multiplexed pattern recognition systems. After a short review on holographic interconnections and optical elements made in DCG we will show that methylene blue sensitized gelatin (MBG) with its enhanced red light sensitivity seems to be a more appropriate recording medium for the fabrication of HOEs to be used in the near-infrared.
