Clicking high resolution pictures in dim light will soon become a reality with an upgrade in present CMOS technology by Fraunhofer University.

Fraunhofer University has brought a technology that removes the the drawbacks of Pinned Photodiodes using pixel size 10 µm or above and helps the cameras capture images in dim light. Scientists have developed the lateral drift field photodetector (LDPD) that helps in boosting the speed of traditional CMOS sensors.

Keeping in mind the changing trends in electronics goods, manufacturers have to make CMOS circuits compatible with the smaller and thinner devices. With the reduced size, it is difficult to capture better quality images many-a-times. The problem is more seen if someone is clicking pictures in dim or no light situations like that in astronomy. Usually bigger size pixels are used opdevelop devices that can amount to faster conversion of light to electrical signal. 

Scientists from Fraunhofer hence introduced an upgrade for the the present CMOS sensors. The speed of conversion in these CMOS sensors has been improved for about 100 times that the initial.

According to a report, the optoelectronic device developed by the team is a lateral drift field photodetector (LDPD) which does not let the generated current to diffuse and sends it at an unprecedented speed to the reading device. The scientists have got the technology patented and the team is now awaiting approval for a series production of the device.
