Self-luminous patterns and patterns on diffusing backgrounds can be recognized in real time by means of multiple holographic filters in an approach that requires no imaging lenses. Use of filters matched to features rather than to entire characters h

A real-time optical correlator is described that uses an ultrasonic light modulator (ULM) in conjunction with an amplitude mask or replica of the signal to achieve linear, phase-coherent detection, without need for high quality optics. When the mask

To realize full benefit from a radar, the analyzed echoes must be strong and sharp. Two options are available: Either the transmitted burst must be an intense, short pulse (often not a propitious arrangement) or the onus can be put on the receiver to

The behavior of a steady‐state argon arc plasma flowing through a cold 1‐cm circular copper pipe at pressures from 0.1 to 1 atm and gas flow rate of 2600 ml/min is studied by microwave cavity techniques. The high electron density (ne>1016 cm−3)

A high-resolution system for measuring the magnetic fields near recording heads and disks has been built. The perpendicular field components close to the head and disk surfaces are measured with an InSb Hall probe which is moved point-by-point under

A coherent optical correlator can operate as a generator of complex waveforms when it is driven by a short-duration carrier pulse. However, the poor signal-to-noise ratio which results usually precludes operation in this mode. The ultrasonic shutter
