Dec 1, 2017 at 9:33 | comment | added | frarugi87 | @Beanluc with "detector" I was not speaking about the speed of acquisition, but the light it can detect. After all, 1 millionth of the original evergy is a very low light to be detected. And moreover, the faster the shutter speed, the larger the light magnitude must be (did you notice that with high speed cameras they usually use very powerful illumination systems?). This means that if you have a faster camera the sensitivity is lower, so maybe you will reach the detection threshold much faster | |

Why not consider an UNcommon camera, with a frame rate of 4.4 trillion frames per second (fastest camera in history), or many tens of thousands of frames per second (many commercially available examples). I'll leave it to you to convert those to milliseconds. | |
