Lighting A modular light-emitting diode system enables flexible lighting arrangements.
Industrial vision uses light to measure.
The reflection of an illuminated widget typically passes through a lens of other imaging system and eventually hits a CCD chip inside a camera. The CCD chip is merely a two dimensional matrix of light detectors which converts the spatial intensity distribution into electrons to form a 2D image. This 2D image is spatially discrete but analog in terms of grey levels. The on-board camera processor then proceeds to convert this image into a video signal and usually outputs it through a connector on the rear of the camera. Finally, the connected computer uses a frame grabber or other digital interface to create a digital image from the video signal input.
