    FIGURE 1. Fiberoptic-coupled CCD cameras (top) have a significantly higher collection efficiency than comparable lens-coupled CCD cameras (bottom). The fiber bundle, with its larger light-capturing area, maintains the incident pattern of illumination and delivers it to the CCD.
    Bonding fibers directly to a charge-coupled device allows significant improvements to be made to image quality and responsiveness in scientific and biomedical applications.

    Recently developed, imaging laser radar systems combine good 3-D resolution and high update rates. Radar pictures of the human form were produced using a staring system currently under development at Sandia National Laboratories (Albuquerque, NM).
    Progress in imaging laser-radar systems has yielded improved performance at lower cost.

    Beta-barium borate (BBO) is commercially available and has a band edge in the UV at 190 nm, but it only phase-matches to 205 nm for second-harmonic generation. BBO crystals are used in generating deep-UV light from solid-state lasers for manufacturing processes such as disk mastering.
    Manufacturers are making the best of available materials and developing new ones in preparation for potentially lucrative and highly competitive markets.
