High-Efficiency Light Valve Projectors and High-Efficiency Laser Light Sources
SMPTE Journal, 1995The optical efficiency of an active matrix liquid crystal display (AMLCD) light valve projector is determined by the optical design, the method of modulation, and the efficiency of the light source. This paper describes a new projector with an efficient modulation technique, which can employ unpolarized light by using a unique diffraction grating ...

High efficiency optical diplexers
Applied Optics, 1982This paper describes various interferometric optical circuits that could provide highly efficient combining of local oscillator and signal beams in heterodyne mixers. Already in use at millimeter wavelengths, they will be of particular importance in optical systems where the available local oscillator power is low.

High power, high efficiency TWT'S
1963 International Electron Devices Meeting, 1963Traditionally, traveling-wave tubes have been thought of as low-efficiency broadband devices. For single frequency operation and bandwidths up to 50mc, klystrons are adequate. Greater bandwidths are conventionally obtained using broadband traveling-wave tubes even though only a fraction of the tube's actual bandwidth may be used.

HIGH-SPEED HIGH-EFFICIENCY ENGINES
SAE Technical Paper Series, 1919<div class="htmlview paragraph"><b>E</b>NGINEERS have different ideas regarding highly efficient and moderately efficient engines, but designers dare not ignore the fact that the public requires today a small very high-speed engine, with good torque at low speeds, and capable of revolving efficiently at very high speeds.
