convert - converts the field from spherical into normal coordinate system.

Calling Sequence

[field_out]=convert(field_in)

Parameters

• field_in :input field. it must be diffractive wavefront.
• field_out : the output field or diffractive wavefront.

Description

converts the field from spherical variable coordinate system into normal coordinate system.

Examples

	f1=begin(0.01,1e-6);
	f2=rect_ap(f1,0.005);
	f3=lens(f2,10);
	f4=lens_fresnel(f3,1.111111,1);
	f5=convert(f4);
	field_plot(f5);
