Abstract
A position sensing device has a substrate, a first portion, a second portion, a two-dimensional photosensor array, a light path and a lens. The first portion is attached to the substrate and the second portion is movably mounted to the first portion along a first axis. The two-dimensional photosensor array is attached to the second portion. The light path extends between a plane and the two-dimensional photosensor array. The lens is positioned in the light path.
Claims14
A scanning device comprising:
- a substrate;
- a linear array of photodetectors operatively connected to said substrate;
