Young company InVisage Technologies at an event in Beijing introduced a new type of image sensor. It is reported that the development took nine years and $ 100 million.
At the heart of the new image sensor is a unique development - a transparent film interspersed with quantum dots. As a material selected metal chalcogenide elements of type II-VI groups of the periodic table. These materials absorb light in a wide range, thus significantly expand the dynamic range of the withdrawn pictures.
New sensors have a number of other advantages over traditional CMOS-sensor. Firstly, they are much thinner. By using film instead of conventional silicon photodiodes thickness sensors has been reduced from 2-3 microns to 0.5 microns. Thin gauges - are thin camera thinnest smartphone. Reducing "depth" of the sensitive layer allow to perceive the light incident at large angles, which further increased the sensitivity. Also increased the area of each pixel sensor that has increased a little more sensitivity.
Second, the light absorption by the new material occurs eight times faster than in the case of CMOS-matrix. This allows to talk about the so-called global electronic shutter. Related Products :
