InVisage Technologies has produced an imaging sensor made with quantum dots.The New Quantum Film sensors are spun from quantum dots into a layer of silicon. Metal circuitry is attached and voila we have a sensor that is ninety percent efficient in absorbing light as opposed to the fifty percent from CCD and CMOS sensors.
“To capture the light, imaging sensors need to have as much area as possible. Powerful DSLR cameras have an imaging sensor that’s about a third of the size of a business card, while camera phones sport sensors that are only about a quarter inch wide (see top photo). Smaller sensors mean less light sensitivity for each pixel on the sensor, and that translates into lower-quality images.”
