The arithmetic used derive Layer1 2*Layer0 To better see the two separate layers the plot window can be shifted into 3D mode. To do this, move the cursor to the origin where there is a small red dot.
  • Page 21: Current Layer

    Current Layer 3.3.3. The layer that is displayed at the top of the plot window is considered to be the current layer. Whatever functions are called act upon this layer. If snap cursors, vertical cursors, or horizontal cursors are displayed, they show up on this layer. The area to the right of the layer name and attributes shows the mathematical function that is operating on the layer.
  • Page 22: Peak Finder

    Smoothing Example Choose the layer that will display the smoothed output and click on the math icon . This will bring up the math menu. In this case the math menu for Layer1 is being shown. The next step could be typed in or the Insert buttons may be used. In the text box, it must read SMOOTH ( Layer 0,5 ).
  • Page 23: Gaussian Plot

    Gaussian Plot 3.3.6.1. When using the LC1-USB for beam profiling, a static function that allows the development of the Gaussian characteristics is included. An example of the use of this function follows. Gaussian Distribution of a Beam 3.3.6.2. The diagram below shows the raw input of laser diode module. In order to define the Gaussian characteristics, extra layers will be added.
  • Page 24 The first step will be to add three more layers: For convenience, it is simple to change the layer names at this point. Highlight the name to be changed and type in the replacement to change the name. Becomes ⇒ All the layers are changed as shown in the following image.

  • Page 26 Using the math icon , select Gaussian Plot from the function drop down menu, or enter GPLOT(center location, peak value, width) in the text box. In this example for the center location at 1300, peak value at 1600 and width at 100 as shown: When the GAUSSIAN and SIGNAL layers are displayed, they appear as shown below.
  • Page 27: Mathematical Functions

    Mathematical Functions 3.3.7. The mathematical functions that can be performed by the LC1-USB allow the user open-ended capabilities. In the previous section, the example used subtraction to take out the background, or dark noise, from the signal. Complex functions may be entered and executed on any given layer except the input layer.
