Abstract
A system for indicating an angular position of an object includes a photoemitter (205) producing radiation. A level detection device (210) contains a movable body (220) in a medium (215) occupying a location dependent on a gravitational angle of the object. The movable body (220) has a different degree of absorption than the medium (215). A photodetector (235) positioned such that the level detection device (210) is between the photoemitter (205) and the photodetector (235) detects an amount of the radiation based on the location of the movable body (220). The amount of the radiation detected indicates the angular position of the object.
