ABSTRACT:
A laser apparatus is provided for sensing rotational orientation or the degree of levelness. The apparatus includes a photosensitive cell and a diode laser directing a laser beam toward the photosensitive cell. Both the diode laser and the photosensitive cell may be mounted in a rigid housing. A ball lens is rotatably mounted between the diode laser and the photosensitive cell such that the laser beam must pass through the ball lens to impinge upon the position sensitive cell. The ball lens is subject to limited movement within the housing. The control for limiting movement of the ball lens may be a circular raceway or a negative lens. Movement of the ball lens within the circular raceway or on the negative lens causes the laser beam to shift on the target. The position of the laser beam on the target is a function of the position of the ball lens and can be correlated to either the rotational orientation of the housing or the degree of levelness of the housing.
