Laser system for generating a reference plane

A laser system comprising:

• a laser transmitter which is operable to generate a laser plane, said laser transmitter comprising a signal receiver and a transmitter control;
• and
• a laser receiver comprising at least one laser sensor comprising a plurality of sensing regions, each of said sensing regions being operable to detect a laser beam from said laser transmitter, said laser receiver comprising an electrical signal transmitter and a receiver control, said laser receiver being operable to transmit a first electrical signal to said laser transmitter in response to said laser sensor detecting the laser beam at a first region of said laser sensor, said laser receiver being further operable to transmit a second electrical signal in response to said laser sensor detecting the laser beam at a second region of said laser sensor, said laser receiver being further operable to transmit a third electrical signal in response to said laser sensor detecting the laser beam at a third region of said laser sensor, said laser transmitter being operable to adjust the laser beam in response to at least one of the first, second and third electrical signals.

A laser system comprising:

• a laser transmitter which is operable to generate a laser plane, said laser transmitter comprising a signal receiver and a transmitter control;
• and
• a laser receiver comprising at least one laser sensor which is operable to detect a laser beam from said laser transmitter, a signal transmitter and a receiver control, said signal transmitter being operable to transmit an electrical signal to said laser transmitter in response to said laser sensor detecting the laser beam, said laser transmitter being operable to one of holding the laser beam at a hold point and oscillating the laser beam within an angle range, the hold point or angle range being a function of an initial location of said laser receiver when detecting the laser beam from said laser transmitter.

A laser system comprising:

• a laser transmitter which is operable to generate a laser plane, the laser plane being adjustable about at least two distinct axes of said laser transmitter to generate a sloped plane at a grade angle with respect to an earth reference in response to a selected grade input, said laser transmitter comprising a signal receiver and a transmitter control;
