Abstract
A system is disclosed for remotely reading out an analog meter having a movable pointer overlying and being mobile over a stationary scale. The pointer is characterized by a first optical reflectivity (R1), and the scale is characterized by a second optical reflectivity (R2). The system comprises an image generator and a detector. The image generator generates an image signal representative of the optical reflectivity of a composite image of the pointer overlying the scale. The detector processes the image signal to generate a pointer position signal representative of the relative position of the pointer with respect to the scale.
