..I'd better do the experiment again. To be honest, I think I'll be happier if I can't reproduce the original results.:smile:

@Charles Link Thanks Charles, the MIT video in the other thread was great to watch, and it is exactly what I observed when using a dielectric beamsplitter- and I came to the conclusion that it was the phase shifts at the beamsplitter interfaces causing that. When using a metallic beamsplitter...

What is strange to me is that the means by which conservation of energy is achieved appears to be altered depending on the type of beamsplitter used.

Not quite 'no light' as the beamsplitter/combiner was not a perfect even split, but the light was greatly attenuated. It is the interferometer that is tuned by adjusting the mirrors to align the beams and adjust the path length. Once that was done the interferometer would slowly drift due to...

For a science fair experiment at high school I built a Michelson interferometer that could achieve a single interference state. Now there are two beams exit from such an interferometer, if a dielectric beamsplitter/combiner is used, one beam exits in a constructive state, and the other in a...

The symbol on the left stands for stress, the value of which can be compared against the yield stress of different materials

Increasing the number of slits effectively produces a phased array, and a stearable beam. A concept that has real world applications in radar and ultrasound.
