Abstract

Image sensors for digital cameras are built with ever decreasing pixel sizes. The size of the pixels seems to be limited by technology only. However, there are also hard theoretical limits for classical miniature camera systems: During a certain exposure time only a certain number of photons will reach the sensor. The resulting shot noise thus limits the signal-to-noise ratio. On the other hand, diffraction sets another limit for image resolution in case that there is enough brightness in the scene. In this work we show that current sensors are already surprisingly close to these limits.
