FIBER OPTIC TAPER COUPLED POSITION SENSING MODULE

摘要

The present invention pertains to a low noise, high sensitivity position sensing module. Fiber optic tapers (20) are coupled to independent, optically and electrically isolated single element detectors (16). The detectors are optionally supported within a mounting plate (12) on one side thereof and the fiber optic tapers are coupled to the detectors on the opposite side of the mounting plate. Since single element detectors are used, the active surfaces (30) of the detectors are shielded both optically and electrically from each other. A laser rangefinder can be integrated with the position sensing module.
