1.6 Design of a line scan camera system
The following figure demonstrates the basic setup of a typical line scan camera system:
Figure 1: Design of a line scan camera application
The following components are necessary in a typical line scan camera application:
Component
No.
Line scan camera: An allPIXA evo camera, which scans the image line by line
and communicates with the PC (5).
1
The optical system: Optical lenses with tubes and mounts with an adjusted
focusing
2
Illumination: The illumination system lights up the information carrier/scan area
on the passing object. The Chromasens Corona II illumination system is an ideal
supplementary option for the allPIXA evo camera.
3
Illumination controller: Controls and monitors the illumination unit. The
Chromasens Corona II illumination (3) has integrated temperature/voltage
sensors which can be read out with the XLC4 controller. By use of the XLC4
controller, the illumination unit can be monitored and kept stable.
4
Fiber optic cable and suitable network card in the PC: The image data are
sent to a PC using one or two fiber optic cables. (6).
5
PC: The PC system performs subsequent processing of the image data and can
optionally control the illumination system (3 + 4).
6
Speed detection: The speed of the object / conveyor belt can be detected by an
optional incremental encoder. The encoder can be connected to the allPIXA evo.
7
Conveying unit: The conveying unit moves the scanned object past the allPIXA
evo camera.
8
Power supply: Both, the allPIXA evo camera and the illumination system, require
a suitable power supply.

2 Specifications and definitions
The allPIXA evo camera family is available in the following maximum resolutions:
◼10,240 pixels
◼15,360 pixels
The allPIXA evo camera comprises all functions required for supplying images with the same
color, brightness and resolution of each operational area.
The allPIXA evo camera is especially suitable for inspection systems requiring a very high speed
and a consistently high color quality.
The camera is compliant with the GigE Vision 2.0 specification which defines the communication
interface protocol for any GigE Vision device. The device description of the camera is contained
in an XML file. For more information for GigE Vision see: https://www.emva.org/standards-
technology/genicam.
The camera can be connected to the PC either with a single copper or fiber cable or with two
cables using Link Aggregation.
Continuous white balancing is possible during image acquisition to ensure optimum color
quality. In addition, offset and shading correction ensure the balance of different color pixel
sensitivities (DSNU and PRNU) as well as the illumination process.
The design was fully revised during development of the housing, which is impressively tough
but offers several screw-mounting options. Take notice that the wide range of adapter options
makes the installation simple for users.
The standard mount connections M72x0.75 for the 10k camera, or M95x1.0 for the 15k camera,
respectively, permit to use all commercially available standard lenses. In addition, special
adapters are available that permit to connect Chromasens accessories.

(also sub-pixel correction, patented)
◼ROI mode (one ROI selectable)
◼Continuous white balancing maintains a constant image brightness and color irrespective
of the temperature and service life of the illumination system
◼Incremental encoder port on the camera; this ensures simple handling and less
programming work
◼Flat field correction, fully automatic calculation internally in the camera
◼Gamma correction, brightness and contrast controller, separate for each channel
◼Robust metal housing
