The Cohu Model
6612-3000
Digital Progressive Scan
camera
enables the user
to acquire full
frame images of
dynamic objects
with the noise
rejection character-
istics of
differential LVDS 10-bit
digital output and no pixel jitter.
The 6612-3000 is
designed to be
used with
external image capture
devices and is
ideal for use in
high-speed “stop
action” applica-
tions.
Progressive scan technol-
ogy eliminates
motion artifacts or
smearing of
moving objects and
provides the full
vertical resolution
lacking in
standard RS-170 video
formats. The 1/2”
format interline
transfer sensor
technology, with
an array size of
659 (H) X 494 (V),
provides
excellent sensitivity with
low
noise.
The Cohu
6612-3000 camera
will operate via
internal clock or
can be configured
to accept timing
from an external
device. The
camera provides
both analog and
digital output. Progressive
scan
mode will support
30 frames per
second from
either a single analog
BNC connector or
10 bits of
digital output from the digital
connector. The
interlaced mode
will enable
capture of 60 frames
per second via
either the dual
BNC connectors or
20 bits of
digital output from the digital
connector.
Selection of operating
mode, shuttering
speed, asyn-
chronous reset
triggers, and gain
can be controlled
through the
auxiliary
connector or via internal
switches. The
camera enables
single image
“snapshot” of events
immediately
after application of
trigger pulse at
a maximum of 60
trigger pulses
per second.
Analog RS-170
and/or 10-bit
digital signals are
supported as
standard
outputs. Analog video
output is useful
for quick setup of
the camera while
the Low Voltage
Differential
Signal (LVDS) output is
used to supply
frame grabbers
with jitter-free input for
applica-
tions that
require extreme preci-
sion and
accuracy.
APPLICATIONS
AND FEATURES
Particle
ImageVelocimetry
High performance
specifications and flexible configurations
enable high frame
rates and accuracy for fluids experiment
solutions.
Laser
Measurement
In “snap shot
mode,” its full frame resolution at fast shutter
speeds improves
beam measurements.
Machine
Vision
60 fps high
resolution video output increases system productiv-
ity and reduces
cost. Asynchronous shuttering supports wide
range of in-line
inspection systems.
Sub Pixel
Interpolation
The CCD imager
provides for stable calibration of instruments.
X-Ray
Imaging
Full-frame
blur-free image with square pixels improves measure-
ment accuracy at
twice the speed of RS-170A cameras.
