| http://www.w3.org/ns/prov#value | - The location of a Talbot plane, i.e., of the diffraction pattern self-imaging plane, is generally at a longitudinal distance of approximately d=(np2/??) from a reticle, where p is the grating spacing of the reticle, ?? is the spectral wavelength of the wavefront, and n is an integer representing the desired Talbot plane (for example, if n=2, then d represents the longitudinal distance from the ret
