Spectra via flat screen TV


Recommended Posts

My wife pointed out the spectral colours in the bedroom flat screen TV last night caused by reflection of the bedside lamp - so I took a picture.  :police:

The multiple diffraction patterns is caused by the tiny LED pixel elements on the screen and may be a accessible 'grating' for testing filters and light sources etc.  Many objects like a CCD sensor show similar diffraction patterns - hope it's of interest :cool:
