To get such less noise you not only need to utilize advanced materials, but also cool down the sensor considerably. To register single photon impacts you'll need to cool down to 0K I guess :-)
- hahainternet 13y agoNot at all, just look at the difference in the current sensors on the market. There's a wide range of performances due to engineering restrictions. Only the pixel size and aperture size are really relevant to diffraction so it occupies a different class of problems.
- Gravityloss 13y agoEven if you had 100% efficient sensors, photon shot noise would still be an issue. You are sampling the photons emitted by the target. After having reasonably efficient sensors, it's a baseline you can't go under.
- wlievens 13y agoI'm not sure about that minimum, but I do know noise (dark current signal non-uniformity for those in the know) increases considerably with temperature. So yes it matters.
- barrkel 13y agoFWIW, the rods in your own eye's retina are able to register single photon impacts.
