Design and Fabrication of High-Efficiency CMOS/CCD Imagers

Economical production of back-illuminated CMOS/CCD imagers should soon become possible. NASA’s Jet Propulsion Laboratory, Pasadena, California An architecture for back-illuminated complementary metal oxide/semiconductor (CMOS) and charge-coupled-device (CCD) ultraviolet/visible/near infrared-light image sensors, and a method of fabrication to implement the architecture, are undergoing development. The architecture and method are expected to enable realization of the full potential of back-illuminated CMOS/CCD imagers to perform with high efficiency, high sensitivity, excellent angular response, and in-pixel signal processing. The architecture and method are compatible with next-generation CMOS dielectric-forming and metallization techniques, and the process flow of the method is compatible with process flows typical of the manufacture of very-large-scale integrated (VLSI) circuits.

Improved Underwater Excitation-Emission Matrix Fluorometer

This is a higher-resolution, smaller, more-capable successor to a prior instrument. Stennis Space Center, Mississippi A compact, high-resolution, two-dimensional excitation-emission matrix fluorometer (EEMF) has been designed and built specifically for use in identifying and measuring the concentrations of organic compounds, including polluting hydrocarbons, in natural underwater settings. Heretofore, most EEMFs have been designed and built for installation in laboratories, where they are used to analyze the contents of samples collected in the field and brought to the laboratories. Because the present EEMF can be operated in the field, it is better suited to measurement of spatially and temporally varying concentrations of substances of interest.

Metrology Camera System Using Two-Color Interferometry

3D locations of multiple targets are determined without mechanical scanning. NASA’s Jet Propulsion Laboratory, Pasadena, California A metrology system that contains no moving parts simultaneously measures the bearings and ranges of multiple reflective targets in its vicinity, enabling determination of the three-dimensional (3D) positions of the targets with submillimeter accuracy. The system combines a direction-measuring metrology camera and an interferometric range-finding subsystem. Because the system is based partly on a prior instrument denoted the Modulation Sideband Technology for Absolute Ranging (MSTAR) sensor and because of its 3D capability, the system is denoted the MSTAR3D. Developed for use in measuring the shape (for the purpose of compensating for distortion) of large structures like radar antennas, it can also be used to measure positions of multiple targets in the course of conventional terrestrial surveying.

Microscope Camera

JENOPTIK Laser, Jena, Germany, offers the ProgRes® CT2 microscope camera with CMOS sensor technology. The ProgRes CT3 is dedicated to bright field and reflective light microscopy, but is also suitable for other contrast methods. Providing a resolution of up to 3 megapixels, the camera captures high-quality digital images especially when contrast methods with high light intensities are applied. The fast live image is available in several resolutions and the integrated CMOS sensor is resistant to blooming.

Display Driver

Matrox Graphics, Montreal, Quebec, Canada, has released the PowerDesk-SE 2.04 display driver that enables a stretched Microsoft® Windows® desktop across up to eight displays. The driver features a joined graphics card mode, which enables two multi-display graphics cards to work in tandem in several Windows desktop combinations. The driver provides more control for displaying information across multiple screens for industries such as energy management and process control. Four modes allow either stretching or cloning of multiple displays.

Ball Lenses

Deposition Sciences, Santa Rosa, CA, has released Iso-SphereTM Antireflection (AR) Coated Ball Lenses for fiber optics, telecom, and datacom applications. The ball lenses are an optical method for collimating the output of an optical fiber or laser diode and can be used in fiber-to-fiber, diode-to-fiber, and fiber-to-detector coupling tasks. DSI’s IsoDynTM low-pressure chemical vapor deposition technology creates a uniformity of the AR coating, eliminating the need for orientation of the lens in the customer’s device.
