THE CIBITE PATTERN FLASH CONTROLLER


THE CIBITE PATTERN FLASH CONTROLLER


CIBITE Flash Panel series is a groundbreaking modular lighting system, based on high power

LEDs, which is designed for the demanding challenges in industrial inspections and machine

vision.


CIBITE Flash Panels are high frequently strobing light sources, which can be triggered by ex-

ternally applied signals for reaching exact synchronization with the picture taking camera. The

CIBITE system stands out due exact flash length timing with an accuracy of a few microseconds.


CIBITE Flash Panels are fully programmable: You can completely configure your area light

source to your needs. If you need a more dark field illumination applied to your object, let only

the area around it flash. If you want to make inner structures of transparent objects visible,

configure your flash light with varying intensities across the illuminated area, so you can em-

phasize edges which would not be visible in uniform illumination.


Otherwise, individual intensity control allows the compensation of LED brightness non-unifor-

mity – so with CIBITE Flash Panels you may reach perfectly evenly lit images – a good starting

point for advanced image processing.


There is the possibility to store four different light patterns into board memory, which can

be triggered independently. So, it is possible to accomplish different tasks with only one light

source.


The CIBITE Flash Panel combines the advantages of high intensity strobing and structured

lighting.


For less complex demands, we provide a second system. With the possibility for setting inten-

sity values for each LED row you are able to apply predefined patterns like stripes or conti-

nuously changing brightness, for instance sinusoidal modulated intensity.


All pictures are taken with the same light source and unchanged camera setup.



The CIBITE Flash Panel board series

•is designed for high speed image acquisition

•is based on high power LEDs.

•is made by highly experienced engineers.


Individual intensity control of each single LED

•allows the compensation of LED brightness non-uniformity - you get an extremely homogeneous illumination.

•allows the application of predefined light patterns like contours - you can simulate a dark field illumination.

•allows the application of gray scale lights or any other modulated intensity - you can make any structures within transparent objects visible.


CIBITE Flash Panel strobe mode:

•provides hardware triggered synchronized image acquisition

•provides exact flash length timing (μs) for repeat accuracy in image acquisition

•provides very short but intense light pulses up to 10 μs duration for fast image acquisition


Configure CIBITE Flash Panels for your specific tasks by:

•choosing board sizes and LED numbers to meet your needs.

•software controlled input voltage adjusting for getting best intensity and flash length values to meet your needs.

•on-board storage of individual LED calibration values to achieve homogeneity of lighting that meets your needs.


With CIBITE Flash Panel lighting systems

•you can start into new dimensions of industrial image processing.

•you can accomplish different tasks with one and the same light source.

•you are ready for the demanding challenges in industrial inspections and machine vision.
