Liquid Crystal On Silicon

Fine pixel size and high-resolution liquid crystal on silicon (LCoS) backplanes have been developed by various companies and research groups since 1973. The development of LCoS is not only beneficial for full high definition displays but also to spatial light modulation. The high-quality and well-calibrated panels can project computer generated hologram (CGH) designs faithfully for phase-only holography, which can be widely utilized in 2D/3D holographic video projectors and components for optical telecommunications. As a result, we start by summarizing the current status of high-resolution panels, followed by addressing issues related to the driving frequency (i.e., liquid crystal response time and hardware interface). LCoS panel qualities were evaluated based on the following four characteristics: phase linearity control, phase precision, phase stability, and phase accuracy.

Spatial Light Modulation

Abstract The Digital Micromirror Device (DMD) is a spatial light modulation Micro-Optical Electro-Mechanical Systems (MOEMS) device used in tabletop projectors, televisions and cinema projection systems. This device creates high resolution, high quality images by deflecting/modulating light with microscopic mirrors. Failure analysis of these devices requires superstructure, package, optics, and substructure approaches. Particles within the active array of a DMD are often killer defects, but those are the subjects of an entire discussion of their own. This paper will show evidence of failures associated with: windows in the package lids, failures of the superstructure area, and failures within the substructure. Methods for removal of the mirrors, as well as other structures, will be covered in greater detail. We will conclude with examples of analysis areas in DMD devices that show how they differ from other types of devices.

Microarray Format

Concepts and results are described for the use of a single, but extremely flexible, probing tool to address a wide variety of genomic questions. This is achieved by transforming genomic questions into a software file that is used as the design scheme for potentially any genomic assay in a microarray format. Microarray fabrication takes place in three-dimensional microchannel reaction carriers by in situ synthesis based on spatial light modulation. This set-up allows for maximum flexibility in design and realization of genomic assays. Flexibility is achieved at the molecular, genomic and assay levels. We have applied this technology to expression profiling and genotyping experiments.
