Abstract
A tamper detection system for a utility meter includes an emitter configured to emit light and a detector configured to receive light. The tamper detection system also includes a light modifying feature coupled to an interior surface of a meter cover. An end portion of the light modifying feature is configured to be positioned proximate to the emitter and the detector while the meter cover is in a closed position relative to the utility meter. The light modifying feature is also configured to alter a direction of travel of the emitted light and to direct the emitted light toward the detector while the meter cover is in the closed position relative to the utility meter.
