Silicon Light Machines’ Grating Light Valve (GLV) devices utilize the principle of diffraction to switch, attenuate and modulate light. A GLV device is a dynamic diffraction grating that can serve as a simple mirror in the static state, or a variable grating in the dynamic state.

The GLV® is a class of Micro-Electro-Mechanical Systems (MEMS) and is built from amorphous, stoichiometric silicon nitride (Si3N4) – a robust high-temperature ceramic well-known for its hardness, durability and chemical stability. Individual ribbons are between 2-4 …

The objective of this paper is to detail the Grating Light Valve™ (GLV™) technology and demonstrate its flexibility in attaining high performance in a variety of optical systems and applications, concentrating particularly on its application

The grating light valve (GLV) is a "micro projection" technology that operates using a dynamically adjustable diffraction grating. It competes with other light valve technologies such as Digital Light Processing (DLP) and liquid crystal on silicon (LCoS) for implementation in video projector devices such as rear-projection televisions .

The Grating Light Valve™ (GLV™) technology is a micromechanical phase grating. By providing controlled diffraction of incident light, a GLV device will produce bright or dark pixels in a display system.

Abstract: The Grating Light Valve™ (GLV™) technology is a micro-electro-mechanical phase grating capable of displaying a unique high-speed modulation of light, combined with grey-scale attenuation. Its electro-mechanical response can be tuned through varied operational and design modes to deliver the required calibrated performances in ...

1997年5月8日 · The grating light valve (GLV) technology is a micromechanical phase grating. By providing controlled diffraction of incident light, a GLV device will produce bright or dark pixels in a display system. With pulse width modulation, a GLV device will produce precise gray-scale or …

2023年12月18日 · A Grating Light Valve (GLV) is a type of micro-electromechanical system (MEMS) used in display and imaging applications. It manipulates light by using a series of parallel ribbons that diffract the incident light, creating constructive or destructive interference patterns.

Valves. Starting with the highly requested Ball Valves, the brand has been based on the principal of quality and performance to match our customers�. needs. Our high standards of production later lead us to incorporate other models such as Gate Valve and Check Valves to our pr.

2010年5月27日 · Like the DMD, the GLV is a digital, reflective technology in which parts of the device are physically moved to alter the path of light shining on the chip’s surface. Unlike the DMD, however, pixels in a GLV reflect light only in their “off” state. In their “on” state, they diffract light in much the same way as does the recorded surface of a CD.
