Creates a one dimensional grating pattern.
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. When the next panel comes up choose "Rectangular" and click next. You will then see the following panel.
Width in meters of one slit of the grating
Width in meters of one period, must be at least equal to slit width plus center shift.
Important Note: If the chosen period is too close to the sampling of the object results may be unpredictable. If you experience problems with this increase your sampling by decreasing the distance between the samples "X Sampling" and "Y Sampling" in the properties of the object. However decreasing these values too much can cause your computer to slow down considerably and even freeze when you try to add, multiply, or replace a piece.
Distance in meters that the center of the slit should be shifted relative to the period; must be smaller than the period minus the slit width.
Angle of rotation in degrees of the entire grating. Choosing zero degrees results in a vertical grating.

The Piece Size window is where the size and location of the grating is
specified. The grating will be re-interpolated based on the sampling of the mask it is being placed into. If the Full Window Button is clicked, then the grating will replace the old mask entirely.

The scaling parameters specify the dynamic range of the grating.
One purpose of Bitmap Scaling is the addition of a phase factor to the grating. |
