Now, colour sensors for better vision in 'Car of the Future'.Byline: ANI Washington, Oct 6 (ANI): Taking a major step towards improved CMOS sensors See CMOS image sensor. for most in-car camera systems, scientists have developed a new process that could provide colours to these systems. The CMOS sensors are semiconductor chips that convert light signals into electrical pulses and are installed in most digital cameras. However, currently the sensors used for industrial and other special cameras are mostly colour blind. Now, researchers at the Fraunhofer Institute for Microelectronic Circuits and Systems IMS (1) See IP Multimedia Subsystem. (2) (Information Management System) An early IBM hierarchical DBMS for IBM mainframes. IMS was widely implemented throughout the 1970s under MVS and continues to be used under z/OS. in Duisburg have developed a new process for producing CMOS image sensors A CMOS-based chip that records the intensities of light as variable charges similar to a CCD chip. Although initially used in less expensive digital cameras, the quality of CMOS sensors has improved steadily. CMOS sensors have advantages over CCDs. which enables the chips to see colour. Normally the image sensors are produced on silicon wafers using a semiconductor technique, the CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. process. "We have integrated a colour filter system in the process. In the same way as the human eye needs colour-specific cone types, colour filters have to be inserted in front of the sensors so that they can distinguish colour," explained Dr. Holger Vogt, Deputy Director of the IMS. And this done via polymers dyed in the primary colours primary colours Noun, pl 1. Physics the colours red, green, and blue from which all other colours can be obtained by mixing 2. Art the colours red, yellow, and blue from which all other colours can be obtained by mixing red, green and blue. Each pixel on the sensor is coated with one of the three colours by a machine which coats the sensor disk propels with a micrometer-thick polymer layer. Using UV light and a mask, which is only transparent on the desired pixels, the dye is fixed at the requisite points and the rest is then washed off. In addition, the researchers have developed special micro lenses, which help the sensor to capture and measure the light more efficiently. Using a transparent polyimide Pronounced "poly-ih-mid." A type of plastic (a synthetic polymeric resin) originally developed by DuPont that is very durable, easy to machine and can handle very high temperatures. Polyimide is also highly insulative and does not contaminate its surroundings (does not outgas). the researchers create a separate lens for each individual pixel, which almost doubles the light-sensitivity of the image sensor. The optimised CMOS process not only makes it possible to cost-efficiently improve the performance of driver assistance systems, but the new properties of CMOS image sensors can also boost the efficiency of endoscopes. The CMOS process was presented at the Vision trade fair from November 3 to 5 in Stuttgart.
