We report on an investigation into optical alignment and tracking for high bandwidth, laser-based underwater optical communication links. Link acquisition approaches (including scanning of narrow laser beams versus a wide-angle ‘beacon’ approach)

A free-space optical 64/spl times/64 fibre-to-fibre crossbar switch with spatial light modulators as the crosspoint elements is described. The design and performance of the optical and electrical components is discussed including lenses, diffraction

We describe the experimental study of phase locking of a four element phased array of fibres, in which the output brightness of the bundle is enhanced by phase locking of the individual elements, and steered by controlling the phase of each channel.

We report the design, build, and test of a multispectral laser beam combining collimator with a spectral range in excess of three octaves. The device is based on a sapphire wedge prism, calcium fluoride, and sapphire collimating doublet lens and fibe

The contrast ratio and the speed of a 16 × 16 electrically addressed spatial light modulator, composed of a ferroelectric liquid-crystal layer on top of a VLSI silicon backplane, are measured with different methods but consistent results. The result

Two-dimensional fiber optic arrays are fabricated for the input and output to a prototype 16-element optical crossbar switch. The switch input comprises a 4 x 4 square array of 125-μm-diam, polarization-preserving fibers with a 5-μm core. The inter

While it is true to say that the Venom carried out more operational ground attack sorties than any other RAF aircraft since the Second World War, its history has hitherto been sadly neglected or misreported. With the co-operation and assistance of ma

This volume contains state-of-the-art research papers on adaptive optics used outside the usual astronomical and military applications. It is the first book to cover this new area of research. One of the main industrial applications is in the control
