Noise Analysis for Complex Field Estimation Using a Self-Referencing Interferometer Wave Front Sensor (Postprint)

Abstract

A noise analysis tor complex field reconstruction from a self-referencing interferometer wave front sensor with an amplified reference is evaluated. The wave front sensor is constructed from a phase-shifting, point diffraction interferometer where the reference field is created by coupling a focal plane image of the input optical filed into an optical amplifier. The noise characteristics of the wave front sensor are examined in terms of the field estimations Strehl. The effects of several systems parameters are examined shot noise, read noise, quantization noise, the relative intensities of the signal and reference fields, spontaneous emission from the amplifier, and phase shift errors
