Abstract
A method and apparatus reduces two types of undesirable glints in an optical position alignment sensor designed to orient at least two components. In one aspect, a method includes using an aperture and a positive optic to block large angle glint generated by the components. In another aspect, a detector is positioned behind the image plane of the components to reduce the effect of small angle glint.
