Local-oscillator boosted tilt sensing using four-step on-axis phase-shifting digital holographic wavefront sensing

Digital holographic wavefront sensors in the on-axis phase-shifting recording geometry (PSRG) can estimate the complex optical field while using a strong local oscillator (LO) to boost weak received signals above the focal-plane-array noise floor. Here, we experimentally demonstrate the measurement of tilt, while boost...
