This short discusses (very briefly) the difference between temporal and spatial incoherence. It also contains a wave animation of a telescope mirror that concentrates a field on a sensor. Of those of you who want to know more about coherence I made these videos: Temporal coherence: https://www.youtube.com/watch?v=dtcq5b0R65w Spatial coherence: https://www.youtube.com/watch?v=nba4ztLBEh0 Presented here are 2D-animations of a field, which means that the intensity of the focused light at the sensor increases with the diameter of the mirror. In a 3D scenario however, the intensity increases with the square of the diameter of the mirror, leading to a much larger difference between the incoming and focused radiation intensity. Simulations were created using the python code supplied by @DiffractionLimited The simulation image file can be downloaded from: https://huygensoptics.com/2D_wave_sims/telescope_incoherent_light.png Milky Way picture by Philippe Donn #short #light #physics #optics
