In this paper, we show that speckle averaging helps to reduce the measurement error
associated with a Shack–Hartmann wavefront sensor (SHWFS); however, this reduction is …

In this paper, we show that speckle averaging helps to improve adaptive-optics (AO)
performance in closed loop as a result of reduced measurement error associated with a …

We provide an in-depth analysis of noise considerations in coherent imaging, accounting for
speckle and scintillation in addition to “conventional” image noise. Specifically, we formulate …

We report wave-optics simulation results and benchtop experimental findings that
demonstrate reduced centroiding error through a Hadamard speckle contrast reduction …

Generating fully developed speckle in a repeatable way is of interest to ongoing scaled-
laboratory experiments. Such experiments often look to validate theoretical and numerical …

In this paper, we use wave-optics simulations to explore the benefits of hidden-phase
compensation for laser systems that employ extended-beacon adaptive optics. Specifically …

Atmospheric induced amplitude fluctuations, known as scintillation, impose limitations on
active tracking and wavefront-sensing performance over near-horizontal propagation paths …

For several decades, the Tyler frequency has provided the tracking community with a
reliable estimate of the bandwidth required to track an object through turbulence …
