Sagnac Interferomter / FOG

Описание к видео Sagnac Interferomter / FOG

A home-made Sagnac interferometer (http://en.wikipedia.org/wiki/Sagnac_i... ) made with fibre-optic cable. The upper right corner shows the interference pattern captured by the camera. When the table is rotated the phase of the beams is shifted and the interference pattern changes. Rotating it in the opposite direction has the opposite effect.

This is how in principle a fiber-optic gyroscope works (http://en.wikipedia.org/wiki/Fiber_op... )
