Photopolymer Holographic Optical Elements
Abstract
The use of holographic optical elements has been under investigation for several applications. The success of some of these applications has been limited due to the properties of the holographic material. The polaroid DMP-128 Photopolymer has several characteristics that appear suitable for Military Optical Elements. The purpose of this program is to investigate the Polaroid Photopolymer Material in applications requiring protection of personnel and optical systems from laser beams. This requires highly efficient holographic mirrors exhibiting transmissions in narrow spectral bands at the laser lines of interest and little attenuation of transmitted light in other spectral regions. The Polaroid DMP-128 Photopolymer is normally stored dry (in a container with desiccant) and has a long shelf life. Under these conditions it is not active. It is made active by impregnating the photopolymer with water. The presently recommended method for adding water is to circulate humid air over the surface for several minutes and immediately make a hologram by exposing the material to interfering laser beams.
