Full angle laser illuminate instrument cluster
摘要:
A display for measured quantities can include a dial plaque with at least one set of indicia spaced around the plaque to indicate the measured quantities. An optical device can be mounted on a shaft within a perimeter of the dial plaque at a location surrounded by the indicia. The optical device can redirect an incident light beam onto the area of the set of indicia. A motor can turn the shaft to rotate the optical device through three-hundred-sixty degrees about an axis of rotation centered on the shaft. Apparatus can be provided for sensing the shaft rotating angular position. A light source can project a light beam on the optical device through the axis of rotation, such that a virtual pointer is generated.
