aperture_transform - transforms a wavefront by an aperture.

Calling Sequence

[dwf_out]=aperture_transform(dwf_in,aperture)

Parameters

• dwf_in :input field.it must be diffractive wavefront.
• aperture : the aperture object.it must be aperture
• dwf_out : the output field or diffractive wavefront.

Description

transforms a wavefront by a type of aperture. now six types of aperture has been designed, they are: circular ( circle ), annular ( annul_ap ), rectangular ( rectang ), hexagonal ( hex_ap ), spidered annular ( spid_annul_ap ), and tiled hexagonal ( til_hex_ap ) aperture.

Examples

	dwf=begin(0.01,1e-6,128);
	ap=circle(0.005);
	dwf=aperture_transform(dwf,ap);
	
	dwf=forvard(dwf,1);
	field_plot(dwf);
