The phase shifts experienced by a polarized light wave when it propagates through media
with arbitrary birefringence, dichroism and depolarizing properties, while on the one hand …

Principles of Adaptive Optics describes the foundations, principles, and applications of
adaptive optics (AO) and its enabling technologies. This leading textbook addresses the …

I describe a nematic liquid-crystal spatial light modulator that can be used as a high-
precision wave-front control device. I present results showing the open-loop correction of …

We have developed an analytical model for the design and optimization of common-path
interferometers (CPI's) based on spatial filtering. We describe the mathematical analysis in …

We present the first results from a real-time closed-loop adaptive optics system incorporating
a liquid crystal based corrector device and a Shack-Hartmann wavefront sensor. The system …

Demonstration of the effect of atmospheric turbulence on the propagation of laser beams is
traditionally a difficult task. This is due to the complexities of long-distance measurements …

Observations withground based telescopes suffer from atmospheric turbulence.
Independent of the telescope size the angular resolution inthe visible is equivalent to that of …

Real-time correction of an optically aberrated wave front by use of a 10× 10 ferroelectric
liquid-crystal spatial light modulator as the correction device and a point-diffraction …

A liquid-crystal optical phased-array technology that uses stressed liquid crystals provides a
new type of tip-tilt wavefront corrector. It demonstrates a very fast time response (10 kHz) …

High-resolution imaging is of great importance in various fields. The use of pupil phase-only
filters (PPF) exceeds the diffraction limit of the imaging system in a simple way. When …
