High quality recording in low light

A team of scientists at Nanyang Technological University (NTU) in Singapore has successfully developed a new image sensor from graphene that promises to improve image quality in low light conditions.

Tests show that it is 1,000 times more sensitive than a semiconductor oxide (CMOS) device. In addition, the sensor operates at much lower voltages, so the power consumption is less than 10 times the normal. New sensors can detect broad spectrum light from ordinary to infrared displays with excellent sensitivity.

This allows the sensor to be suitable for a wide variety of cameras, including infrared cameras, traffic safety cameras and satellite imagery. According to NTU, this technology allows photographers to record clearly. Clearer in many light conditions. It is predicted that mass production will be 5 times cheaper than current sensors.

A team of scientists led by Associate Professor Wang Quijie conducted the study over the past two years. According to Wang, the invention will have a huge impact not only on the imaging industry but also on the satellite, media and infrared industries.

Wang said that it is possible to use a conventional CMOS sensor production process to produce graphene sensors, so it is convenient and cost-effective to produce.
