Effects of Wavelength Change in Holographic Reconstructions

Abstract

Holographic imaging is necessary in some particulate measurements in test facilities at AEDC. Additionally, projection of holographic images of infrared (IR) test objects is being considered to enhance the IR sensor test capability at AEDC. Lasers of different wavelengths often are necessary in the recording and reconstruction of the required holograms. As a result, a study of the effects of a wavelength change between the recording and reconstruction illumination on the aberration, resolution, and location of holographically reconstructed images was experimentally undertaken. Control of aberration and resolution degradation, to the extent possible, is described.
