Sinusoid gratings : POD068135

The transmission sinusoidal grating (or holographic grating) allows an easy understanding of the notion of Fourier’s transform.

It creates 3 beams coresponding to the 0, -1, +1 orders and allows the analogy with Fournier’s transform of a sine wave when a laser goes through it.

The holographic processing is done on all the grating’ s surface area, with a 1000 lines/mm path.

Slide size: 50 x 50 mm.
