Title: Mechanical grating device

Abstract: A mechanical grating device for diffracting an incident light beam has a base which defines a surface. A spacer layer is provided above the base, said spacer layer defining an upper surface of said spacer layer. A longitudinal channel is formed in said spacer layer, said channel having a first and second opposing side walls and a bottom. The side walls are substantially vertically disposed with respect to the bottom, and said channel having a constant cross section along the entire length of the mechanical grating device. A plurality of spaced apart deformable ribbon elements are disposed parallel to each other and span the channel. The deformable ribbon elements are fixed to the upper surface of the spacer layer on each side of the channel.
