ABSTRACT:
A pointer for use with an analog meter movement providing a luminous indication of the meter position. The present invention provides an analog meter movement indicator which selectively directs a laser light or other collimated beam across the contoured face or dial or an analog meter, wherein the selective movement of the light beam and the resulting luminous image is provided by a selective movement of an optical deflector mounted on the shaft of the meter movement. The optical deflector is optically energized by an externally mounted, stationary light source. As the meter movement shaft is rotated, the luminous beam image moves over the dial face according to the signal applied to the meter movement. The resulting instrument provides a dramatic indication of analog meter signal presentation.
