Effect of point-ahead angle on scintillation in laser satellite communication systems equipped with adaptive optics

Some ground-based optical terminals used in optical uplinks employ adaptive optics (AO) to pre-correct the outgoing, data-carrying laser beams, which helps reduce scintillation and other, turbulence-induced signal im-pairments. The beacon photons can come from the satellite itself or from a natural guide star. After AO...

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...
