One Dimensional Grating

Creates a one dimensional grating pattern.

Getting Started

Right click on the object in which a one dimensional grating is desired. The object can be a target, source, detector, or any object using the 2D viewer. Click edit to bring up the properties editor. Choose “Replace A Piece” from Menu Items and click go. When the “Replace A Piece” wizard comes up, choose “One Dimensional Grating” and click next. You will then see the following panel.

Choosing a Grating:

  • Rectangular: Rectangular grating specified by slit width, period, center shift and angle.
  • Fourier Series – Direct Input: Grating is created by a Fourier transform using sine and cosine functions for the basis functions. Up to 10 coefficients for cosine and 10 for sine can be input.
  • Fourier Series – Catalog: Grating is created by a fourier transform using coefficients that have already been figured out for you.
  • Fourier Series – Trapezoidal: Trapezoidal grating specified by base width, period, angle, and number of coefficients.
