The application of sub-micron particle visualisation for PIV (Particle Image Velocimetry) at transonic and supersonic speeds
Abstract The technique of PIV (Particle Image Velocimetry) provides an instantaneous whole field visualisation in a plane of a flow field. This is achieved by projecting a plane of light into theExpand

New approach to color-variable light-emitting devices based on conjugated polymers
Recently there have been reports on color variable light emitting devices. Here we present a new approach to such devices based on conjugated polymers. the device consists of a blend ofExpand

Continuous Tone Holograms By Halftoning
In previous reports we described a way of writing very high accuracy binary computer holograms by CRT writing of interferometrically abutted cells by half toning in the CRT plane which can result in continuous tone on the hologram. Expand
