Paper Abstract

The optical profile measuring method described earlier was analyzed with the assumption of infinite lens apertures. A more detailed analysis shows that the presence of finite apertures induces a focal shift in addition to the well known effects on spot size and shape. The calculations lead to a modified design for the profilometer with better performance.
