Abstract

The fundamental validity of using an interferometric process to reduce scattered light in optical systems has been examined from a physical optics viewpoint. An elementary scatter nulling interferometer was considered in the context of a simple telescope system as it imaged a distant point source, whose image had been degraded by a single on-axis point scattering source. With the interferometer inserted in the optical train of the telescope, the diffraction image of the point source, and a wavefront model of the scatter source at the focal plane were studied in detail. An expression for gain in signal-to-noise ratio was evaluated for typical cases. An experiment to illustrate the basic concepts of a particular scheme was conducted to demonstrate the viability of the technique.
