Holographic methods for the investigation of photophysical properties
Abstract
Holography is most frequently thought of as a method of photography that results in three dimensional images of the object being photographed. Holography is also used as a powerful tool for the investigation of a variety of photochemical and photophysical processes. These experimental techniques rely on the fact that small spatial modulations of the materials optical properties (index of refraction and absorption coefficient) defect an incident light beam into another direction. By following the growth or decay in intensity, the underlying physical process producing the changes in optical properties is followed. If a continuous wave laser is used to produce the hologram one uses the technique to investigate solid state photochemistry. If a pulsed laser is used, a broad range of time dependent processes are investigated.
