Light Machinery (Ottawa, ON, Canada) produces wafers, etalons, prisms, beam splitters, windows, and other flat optic products, as...

A manufacturer is looking for a detector array for the infrared region to detect two-dimensional radiation patterns. The sensor should have 1000 x 1000 pixels (or at least 512 x 512 pixels), which are individually addressable. The detector array is comparable to a high-speed CCD chip, but must have high sensitivity in the...

The qualities that we expect in our cell phones and PDAs -- anytime connection and low-cost, widely available devices -- soon may become common in health-care devices at home and in doctors' offices. The University of Florida (UF) and IBM have developed a new technology that creates a roadmap for widespread commercial...
