Reflections on glass making

Greg Blackman explores some novel ways of imaging glass, including a 3D technique to measure the flatness of glass panels

Tichawa Vision (1H42) will present its Diamond contact image sensor (CIS) product family, which has a line rate of up to 1,000 kHz. The sensor has a pixel array with powerful signal pre-processing (correlated double sampling, plus on-chip linearisation) and around 1,000 ADC levels with suffixed serialisers. The sensor also has 17 LVDS drivers, each with 622Mb/s of aggregate data rates of over 10 Gbaud.

At web speeds of 21m/s the CIS achieves a resolution of 1,200dpi. The correlated double sampling gives a dynamic range of 60dB.


The industrial scanner streamlined for digital, inkjet and security printing has been equipped with new functions, which automatically recognise missing nozzles at a resolution of 1200 dpi
