Attainment of High Resolution Holographic Fourier Transform Spectroscopy

Abstract

Two methods are described to attain high resolution holographic spectroscopy. One is an interferometer construction to record the localized interference fringes on the photographic plate directly. The limitation due to the use of an imaging lens is removed. The other is the application of heterodyning techniques to holographic spectroscopy. By this method, a hologram with high resolving power is recorded on relatively low resolution photographic film.
