Paper Abstract

This paper describes an application of holographic to product diffusers with different optical properties. We report on holographic diffusers for making uniform the infrared source radiation patterns with a variable dispersion angle. The holographic recording geometry provides control over the angular dispersion characteristics of the diffuser. Multiple-lobe and multiple-spot holographic diffusers with 3D scattering patterns have been fabricated. The scattering pattern is achieved by recording a diffuser. We provide some details on the recording set-up and procedure. We discuss some holographic properties of DuPont holographic recording films used in this application. Measurements of the scattering properties are presented for diffusers made in DuPont holographic recording films. For a holographic multiple-spot diffuser, the optical channel frequency response was measured and compared with an opal glass diffuser.
