Description Retrieves the HOE diffraction grating from a specified surface.
Syntax GetDiffractHOE( n, tGrating , phaseType, coeffs )
Parameters n As Long Node number of the grating surface being queried
tGrating As T_HOE After the subroutine executes, this variable will be populated with the construction data of the grating.
phaseType As String Returns the type of aspheric phase deformation from the grating. Can be "None", "Radial polynomial", or "XY polynomial".
coeffs() As Double Array containing the coefficients of the phase deformation polynomial.
For the x,y polynomial phase departure type: •The index of coefficient Aij in the array is j + (i*(i+1))/2 •There are i+1 terms of degree i •There are (n+1)(n+2)/2 terms up to and including degree n
