for use in
workstations running Video Management Sys-
tem software, and it supports simultaneous de-
coding of multiple video streams at multiple res-
olutions from a variety of cameras and codecs.
It comprises an information processing video
decoder board and a full high-definition (HD)
quad-output board. The former offloads video
decoding from the host CPU, enabling it to
focus on access control, system configuration
and situation management. The output board
displays multiple individual streams in native
resolution at full frame rates on up to four HD
Along with a KTN scanner chip, NTT AdvancedTechnologies has introduced a KTN (potassiumtantalite niobate) module that is a fully adjustable multidirectional beam-steering scanner.
The 2 ; 3 ; 6-cm scanner contains no moving
parts because the deflection stems from electron
redistribution induced by applying an external
voltage, resulting in operating speeds of up to
1 MHz. Wavelength range is from 532 to 4000
nm, beam diameter is <1 mm, and deflection
angle is 10° ± 5°. Applications include laser pro-
cessing, 3-D measurement, optical communica-
tions and recording, displays, imaging, sensing,
printing and copying.

tain a constant laser diode temperature to im-
prove wavelength, power and pointing stabili-
ties. Available with 50, 100, 150 and 200 m W
of output power, it is suitable for use in hot
steel and glass inspection, positioning, and re-
search and development. The TEM00 beam has
a Gaussian profile and typical M2 of 1.6.
Polarization ratio is 4:1, bore sighting is < 3
mrad, and operating temperature is from – 20
to 45 °C.
