摘要：
A system and method for accurately determining the positioning of a lens system. The lens system includes a lens and a variable light reflecting surface. A position sensor includes a light source and a light detector. An initial signal is sent from the light source to the variable light reflecting surface. The light reflecting surface reflects the initial signal to the light detector at a reflection region. The intensity of the reflected signal is dependent upon the location of the reflection region. An electrical output signal is generated based upon the reflected signal from the light source, with the electrical output signal providing positioning information for the lens system.
