TWO APPROACHES TO LINE-SCAN
Modular concept with single components
Combination of line scan camera, lens and external line light
Scalable resolution and field of view
Significant working distance
Usable for flat and uneven objects
Multi scan or multi camera
CIS unit as integrated package
Integrated unit: Sensor, lens and lighting in one
housing
Pixels are mapped 1:1 to the object with lens array
Small working distance
No lens effects (distortion)
Easy alignment
Only for flat objects because of low depth of focus
CIS CONFIGURATION
Key components
Integrated LED, high intensity and homogeneity
Selfoc lens array, 12 mm working distance
Sensor IC (Array)
High speed operation
Precise chip alignment
ASIC chip for image processing
Pixel correction, line alignment
Digital output with CameraLink interface
CIS CONFIGURATION
Composition of the lens unit
Imaging with selfoc lens array
Gradient lenses
Linear arranged
Each lens forms a small image
Image circle is larger than lens
aperture
Two or more rows

FRAME GRABBER ADAPTION
How to acquire and process high speed image data?
Example: CIS KD 926mm with 22k pixels (DIN A 0)
Data rate up to 1.5GB/s
3 CameraLink Medium frame grabbers required!
Our recommendations are:
Frame grabbers with on-​board FPGAs for real-time pre-processing
Silicon Software microEnable IV
Teledyne DALSA Xcelera VX4
Supported by Common Vision Blox

STRATEGIC PARTNERSHIP
Mitsubishi Electric has many years of experience in the
development of compact optical colour readers, mainly
for high-end document scanning with the highest scan
rates.
The new KD series of CIS feature a CameraLink
interface, increased working distance and higher
speeds and are the first CIS targeted at the Machine
Vision industry.
STEMMER IMAGING is the strategic partner for the
distribution of Mitsubishi Electric Europe´s CIS
throughout Europe.
Thank you for
your attention!
