Optical Metrology - Some Personal Reflectionsor standards, and spectral and temporal measurement of spatial effects. Despite the exciting progress observed a major non-scientific problem is noted: the widespread failure of most academic institutions to treat and teach optical metrology as a coherent discipline. Some reasons for that failure ar

Some Recent Developments in Laser Interferometrynsing device. The first of these developments, termed the double pass attachment, is an optical accessory which doubles the resolution of the Hewlett-Packard linear and plane mirror interferometers. Unlike previous attempts to extend resolution optically, this device does not fold one of the two int

Laser Heterodyne Probes then, the applications have broadened out into a number of other areal such as imaging, optical communications and metrology..A heterodyne interferometer can be considered as a modified Michael son interferometer in which the beam splitter element has been replaced by a Bragg cell. This has the eff

Laser Velocimetryhe crossbeam setup and the dual focus setup are discussed. With respect to electronic circuity for the extraction of timing information, the frequency counter, the tracker with phase locked loop, the time to amplitude converter with multichannel analyzer, and the photon correlator are described.
