Abstract

A device for measuring an increment on a surface comprises a housing having a left light source, a right light source and center light source each configured to project a light beam onto a target surface. Each light source is independently rotatable, and in communication with a rotation measuring element configured to measure a degree of rotation of each respective light source. A computing unit is configured to receive a measured degree of rotation value from the rotation measuring element for each of the left light source and the right light source, and to calculate a rotation target value for the center light source corresponding to a desired incremental point on the target surface between a projected left light beam from the left light source and a projected right light beam from the right light source, such that the center light source can be rotated according to the rotation target value and project a center light beam at the desired incremental point.

Claims (13)

1. A device comprising:

a housing comprising a left light source, a right light source, and a center light source, each light source configured to project a light beam onto a target surface;

wherein each light source is independently rotatable, and wherein each light source is in communication with a rotation measuring element configured to measure a degree of rotation of each respective light source; and

a computing unit configured to receive a measured degree of rotation value from the rotation measuring element for each of the left light source and the right light source, and to calculate a rotation target value for the center light source corresponding to a desired incremental point on the target surface between a projected left light beam from the left light source and a projected right light beam from the right light source, such that the center light source can be rotated according to the rotation target value and project a center light beam at the desired incremental point.

2. The device of claim 1 , further comprising a display unit on a face of the housing configured to indicate when the center light source has been rotated to match the rotation target value.

3. The device of claim 2 , wherein the display unit further indicates an angle of rotation of each light source.

4. The device of claim 1 , wherein the center light source is automatically rotated according to the rotation target value.

5. The device of claim 1 , wherein the incremental point is a midpoint between the projected left light beam and the projected right light beam.

6. The device of claim 1 , wherein each of the left light source, the right light source, and the center light source comprise a laser.

7. The device of claim 6 , wherein each rotation measuring element comprises a potentiometer.

8. The device of claim 1 , wherein each of the left light source, the right light source, and the center light source are at least partially enclosed by the housing.

9. The device of claim 8 , wherein each surface of the housing is substantially planar and without protrusions.

10. The device of claim 1 , wherein at least one of the left light source, the right light source, and the center light source comprise a beam splitter.
