CMOS Digital Photo IC for Colour Sensing
Jul 27 2009
Hamamatsu Photonics (UK) introduce a 12-bit digital output colour sensor Photo IC. The S9706 device consists of a matrix photodiode array, coupled to a RGB (red, green and blue) filter matrix to give colour response. The device is combined with “in house” CMOS processing electronics and is all contained within a monolithic silicon chip. The output of the S9706 is in 12-bit digital format with the colour intensity of red, green and blue read out sequentially at potentially high speed.
The S9706 is easily operated with a standard 3.3V CMOS power supply and has higher speed and is much lower in cost than three colour image sensors. It is also highly accurate and is easier to implement than current discrete three colour photodiodes. The S9706 is ideal for applications such as colour sensors for displays (LCDs, televisions & monitors), colour rendering for LED backlights, office and industrial lighting control, in-line industrial product inspection, colour printing applications, bank note verification, environmental sensors and a wide variety of other optical sensors requiring colour measurements.
