1 Introducing the SK7500GTO-XL Line Scan Camera
1.1 Intended Purpose and Overview
The SK line scan camera series is designed for a wide
range of vision and inspection applications in both
industrial and scientific environments. The GigE series
camera SK7500GTO-XL uses the Gigabit Ethernet
communication protocol, enabling fast image transfer
using low cost standard cables up to 100 m in length. The
Gigabit Ethernet interface makes the line scan camera
highly scalable to faster Ethernet speeds, distinguishing
it with high performance and total flexibility.
All of the GigE cameras from Schäfter+Kirchhoff are
externally synchronizable and no grabber board is
needed as signal preprocessing is performed inside the
camera and does not impinge on CPU use.
Additional features include:
•
customer-specific I/O signals in addition to the video
signal
•
special preprocessing algorithms can be implemented
in the camera
•
consistent attribution of camera IDs in multi-camera
operations
•
SDK from Schäfter+Kirchhoff with the SkLineScan
operating program, libraries and examples.
The camera can be connected to a computer either via
the GigE socket directly or through a Gigabit Ethernet
switch.
Once the camera driver and the SkLineScan® program
have been loaded from the SK91GigE-WIN CD then the
camera can be parameterized. The parameters, such as
integration time, synchronization mode or shading
correction, are permanently stored in the camera even
after a power-down or disconnection from the PC.
The oscilloscope display in the SkLineScan® program
can be used to adjust the focus and aperture settings, for
evaluating field-flattening of the lens and for orientation
of the illumination and the sensor, see 3.1 Software:
SkLineScan, p. 12.
