description This disclosure presents an apparatus to improve the position sensing of a moving mechanism, such as a fluid valve located within a borehole. The apparatus can utilize a light beam or an optical fiber to measure changes in the position sensor. The smaller and lighter apparatus can improve the accuracy of the sensing mechanism. In addition, three systems are presented. The first system utilizes a vibration sensor, such as a MEMS, and an accelerometer to calculate changes in the mechanism position of the moving mechanism. The second system utilizes a radiation source and detector combination, along with a moving radiation shield to provide more accurate position sensing than conventional techniques. In addition, a lens-based system is presented, that when combined with a radiation source, can calculate position information by detecting the diffusion or dispersal of the radiation against a radiation detector.
