 Our project called Single Photon Visible Light Image Sensors for Science and Technology seeks to lay the foundations for transformational changes in low light imaging in many areas of science and technology, such as astronomy, adaptive optics, spectroscopy, quantum technologies, autonomous systems and life sciences. The imaging performance of such sensors would be limited only by the photon absorption in the semiconductor and the quantum nature of light. By detecting and counting each and every photon without registering any additional noise, these sensors could offer the ultimate imaging performance, helping us see and discover the unknown.
