wavefront_header - construct a diffractive wavefront header.

Calling Sequence

[dwfh]=wavefront_header(lambda,pixscale[,axes_x[,axes_y[,tf]]])

Parameters

• lambda : the wavelength in meters.
• pixscale : the pixel scale in meters.
• axes_x : the grid dimension in X direction, default axes_x = 256.
• axes_y : the grid dimension in Y direction, default axes_x = 256.
• tf : the 3D frame.
• dwfh : the output difractive wavefront header.

Description

construct a diffractive wavefront header.

Examples

	number=256;
	wavelength=1e-6;pixscl=0.1;
	dwfh=wavefront_header(wavelength,pixscl,number);
