Engineers from Dartmouth’s Thayer School of Engineering have produced a new imaging technology that may revolutionize low light imaging. Called the Quanta Image Sensor, or QIS, this new light sensing technologyenables highly sensitive digital imaging in low light situations. QIS technology is able to reliably capture and count single photons, with resolution as high as one megapixel.
This sensor produces binary single-photon image, so if the pixel was hit by one or more photons, it is white; if not, it is black. Take many images at fast speed, and you can produce grey scale images.
