Abstract
An alignment system includes a laser transmitter and receiver. The receiver includes a linear photodetector array centered at a predetermined location with respect to machined surfaces that define a receiver reference plane. An indicator on the receiver displays a deviation of the position of the laser beam from a predetermined location on the photodetector array thereby to quantify any misalignment of a surface supporting the receiver with respect to the transmitted laser beam.
Claims18
An alignment system comprising:
- A) a transmitter for projecting a laser beam along a projection axis;
- and
- B) a receiver including:
- i) a housing with means for defining a receiver reference plane,
- ii) detector means having a predetermined location in said housing relative to the receiver reference plane for generating an enabling signal which causes a visual indicator on the receiver to announce that the receiver is receiving a laser beam in response to detecting at least a predetermined laser beam intensity on said detector means,
- iii) means responsive to the enabling signal from said detector means for generating a quantitative value as a display of the position of the laser beam projection axis relative to the predetermined location and the reference plane.
