Thin Y2O3 films have been fabricated using a Langmuir–Blodgett (LB) process. Uniform LB films of yttrium arachidate have been successfully deposited up to 200 layers. These films were found to decompose uniformly above 300 °C leaving a thin oxide layer. X-ray diffraction, laser reflection, and Rutherford backscattering have been used to determine crystal structure and stoichiometry of the film before, during, and after thermal decomposition. This test system demonstrates the potential application of Langmuir–Blodgett deposition for inorganic oxide film fabrication of thicknesses ranging from 0.1 to 40 nm.

The Grating Light Valve (GLV™) technology offers a unique combination of extremely fast switching speed and the ability to withstand very high optical power densities. These and other attributes enable a novel architecture based on a scanned linear array of GLV pixels, which is described here for the first time. This architecture provides a number of advantages over conventional projection display systems that are based on either 2-D spatial light modulators or scanned point systems. These advantages include scalability to very high spatial resolution, natural analog gamma response, high contrast and dynamic range, high optical efficiency, and low cost at production volumes.

The objective of this paper is to detail the Grating Light Valvemi (G1..vTNI) technology and demonstrate its flexibility in attaining high performance in a variety of optical systems and applications, concentrating particularly on its application toward projection display systems. The GLV technology represents a unique approach to light modulation and offers remarkable performance in terms of contrast, efficiency. switching speed, and cost. 'I'he electro-inechanical response of the GL\7 device can be tuned through various design and operational modes to deliver desired performance for a given application. The design and fabrication of a linear array module of 1,088 GI.V pixels is described. This module enables a Scanned Linear GLV Architecture for HDTV projection products. The flexibility of the GLV technology and the Scanned Linear GLV Architecture can support line sequential and frame sequential color, as well as 3-valve color systems. System level optical designs either include embedded scanners to emulate 2-D film source planes or external scanner elements for greater system simplicity. Results with actual projection display systems yield unparalleled on-screen performance, having uniformity greater than 99% corner-to-corner, high contrast, 10-bits of grayscale per color, and no visible pixel boundaries.
