b_mix - mixes two coherent wave fields into one wave field.

Calling Sequence

[field_out]=b_mix(field_in_1,field_in_2)

Parameters

• field_in_1 :the first input field. it must be diffractive wavefront.
• field_in_2 :the second input field. it must be diffractive wavefront.
• field_out : the output field or diffractive wavefront.

Description

The input fields must be the same as dimensions, sizes, wavelengths and the coordinate systems.If not the same dimensions, you can use comammd interpol resize the field, then mix the two coherent fields.

Examples

	m=1;nm=1e-9*m;mm=1e-3*m;cm=1e-2*m;
	lambda=550*nm;sizes=5*mm;N=100;
	R=0.12*mm;d=0.5*mm;z=100*cm;
	F=begin(sizes,lambda,N,N);
	F1=circ_ap(F,R,d,0);
	F2=circ_ap(F,R,-d,0);
	F=b_mix(F1,F2);
	out=forvard(F,z);
	field_plot(out);
