tilt - introduces tilt into the field distribution.

Calling Sequence

[field_out]=tilt(field_in,tx,ty)

Parameters

• field_in :input field. it must be diffractive wavefront.
• tx : the tilt of the X direction in radians.
• ty : the tilt of the Y direction in radians.
• field_out : the output field or diffractive wavefront.

Description

filters the field through tilt filter. tx and ty must be passed to even if one of the two equals to zero

Examples

	f1=begin(0.04,1e-6);
	f2=rect_ap(f1,0.02);
	f3=tilt(f2,1e-4,-1e-4);
	f4=forvard(f3,8);
	f5=cros_out(f4,"out");

	temp = fscanfMat('out.txt');
	x=zeros(1,256);pha_x=zeros(1,256);
	x(:)=temp(:,1);pha_x(:)=temp(:,4);
	plot2d(x,pha_x);
