ICCD
high speed camera
equipped with analog output:
|
|
ICCD cameras with analog video output are
connected to the PC by two cables.
A 50 Ohm coaxial cable transfers the video data from the camera to the frame
grabber inside of the PC. An additional
serial interface cable features the remote control of the camera
systems. Setup and control commands are uploaded to
the camera by the serial interface cable and acknowledgements as well
as camera status informations are downloaded to the PC.

ICCD
high speed camera equipped with CameraLink
digital output:
The theoretical
maximum
frame transfer rates
are:
- high resolution CCD chip = 2.8 MB/frame =>
107
frames/s
- standard resolution CCD chip = 0.9 MB/frame
=>
333 frames/s

ICCD
cameras
with
digital video output are available with either
CameraLink
interface or High Speed USB 2.0 interface. They are connected to the PC
by
a single cable respectively which transfers both image data as well as control signals.
The advantage of
the CameraLink
over
the High Speed USB interface is
the theoretically 300MBps data transfer rate, which is 5 times higher
than High Speed USB. Yet, the CameraLink connection needs a frame
grabber board in your PC.

ICCD
high speed camera equipped with USB 2.0
digital output:
The theoretical
maximum
frame transfer rates
are:
- high resolution CCD chip = 2.8 MB/frame =>
21
frames/s
- standard resolution CCD chip = 0.9 MB/frame
=>
66 frames/s

With the High Speed USB
interface you do not need any frame grabber.
You can plug your camera into every PC or even Laptop and play. High
Speed USB offers you maximum flexibility in the laboratory and the
field. However, compared to the CameraLink interface High Speed USB is
somewhat limited in frame transfer rate. It offers 60 MBps which
results in the theoretical maximum frame transfer rates shown
under the drawing in the left column.
In order to overcome these restrictions with the
High Speed USB, we
offer additional on-board memory to increase the frame aquisition rate
independent of the frame transfer rate to the PC. Further increasing of
the frame transfer rates may of course be performed by binning. |
Note: Gigabit
Ethernet is coming!
Gigabit Eithernet
interfaces will be available in most PC`s and Laptops
as an option or even as a standard in a few years. 10Gbps = 1.25GBps
will then offer the ultimate frame transfer rate without the need for a
frame grabber and enable highest data transfer rates along with maximum
flexibility and ease of use also with your Laptop.
STANFORD COMPUTER OPTICS intensified CCD cameras will then be
upgradable to Gigabit Ethernet standards. |
