RASTER
Some models of the Series 9000E Scanner/Decoder are supplied with a
raster scan option. Not only does the beam scan horizontally but it is
also incremented vertically so as to sweep an area. The area covered
depends on the raster deflection and the distance from the scanner. The
unit is available with 5
o
, 10
o
, 20
o
, and 30
o
deflection. Figure 3-6 below
shows the area covered for various deflections and distances from the
scanner. For 500-scan/sec. models, six sweeps of the beam are equally
spaced over the raster height. For 1000-scan/sec. models, twelve
sweeps are equally spaced over the raster height.
