摘要： A transmitter for an alignment system in which a field of electromagnetic radiation is propagated in a non-planar reference cone is disclosed. The transmitter includes a chassis with a source fixed to the chassis for providing a beam of electromagnetic radiation and an optical deflector which converges toward the source reflects the beam into an omni-directional cone of radiation. A flexible support having an omni-directional stiffness supports the optical deflector in the beam to reflect the reference field in a level orientation when the chassis is level. An angular error in the orientation of the chassis from level results in the optical deflector deviating from the aligned position to maintain the reference field in the level orientation. Damping of the deflector is also provided for and sensors detect when the angular error of the chassis has exceeded an allowable amount.

摘要： A transmitter for an alignment system in which a field of electromagnetic radiation is propagated in a non-planar reference cone is disclosed. The transmitter includes a source for providing a collimated beam of electromagnetic radiation directed parallel to a beam axis. A cantilever strand supports a bob within the beam. The bob has a conical reflecting surface to reflect the collimated beam conically. Optimally, the cantilever strand and bob are chosen to provide a deflection between the bob and plumb which is substantially one-half of any angular error between the beam axis and plumb. In an especially preferred form, a housing surrounds the bob and has inner and outer surfaces which minimize temperature effects on the orientation of the reference plane. Also, detectors are provided to sense when the angular error between the beam axis and plumb is outside of an acceptable range.

摘要： A laser beam alignment system includes a transmitter which establishes a laser reference plane by continuously rotating a horizontal laser beam about the transmitter. A remotely located receiver senses the elevation of the laser reference plane and reflects a portion of the laser energy back to the transmitter where the reflected energy is employed to produce a signal indicative of the range of the receiver and its location with respect to a reference axis. The position of the receiver is thus established in three dimensions.

摘要： A laser beam three dimensional position measurement system includes a laser transmitter mounted at a stationary reference position at a work site and a receiver mounted on a mobile machine at the site. The transmitter produces a laser reference plane by sweeping a laser beam about the transmitter. The receiver includes a retroreflector which intercepts and reflects laser energy back to the transmitter when the laser beam sweeps past the retroreflector. The system also includes at the transmitter a circuit composed of a photodetector, timer, clock and counter. The photodetector senses laser energy reflected back to the transmitter from the retroreflector. The timer modulates the laser beam produced by the transmitter in response to detection of the beam. The counter is connected to the clock and timer, and is enabled by the timer to start counting electrical pulses received from the clock when the beam is modulated. The counter is disabled to stop counting electrical pulses when the modulation is detected. The number of pulses counted by the counter is indicative of the range of the receiver from the transmitter. The orientation of the beam relative to a fixed reference axis at the time reflected laser energy is detected defines the direction of the receiver relative to the transmitter.

摘要： Apparatus operable in accordance with the method of the present invention for measuring the angle of incidence of a light beam or plane relative to level comprises a photodetector array for sensing the light and a level mirror preferably comprising a pool of mercury. Optics are provided for transmitting the light to the photodetector array in alignment with the angle of incidence of the light (aligned light) and also after the light has been reflected from the mercury pool (reflected light). A shutter is provided for separating aligned light from reflected light such that distinct signals representative of the two are generated by the photodetector array. The distinct signals are processed by up-counting and down-counting a counter circuit to determine the average centers of light spots representative of the aligned light and the reflected light and the distance between those average centers which is representative of the deviation of the light beam or plane from level.

摘要： A system for dampening vibratory motion of a pendulous compensator in a laser beam projector includes a beam splitter which diverts a portion of a laser beam deflected by a mirror mounted on a cantilever beam of the compensator, and a photocell device having a pair of photodetectors positioned to receive the diverted laser beam portion and sense oppositely varying proportions thereof corresponding to the displacement of the position of the deflected laser beam. Two output signals are produced corresponding in magnitudes to the respective proportions of the diverted laser beam portion sensed by the photodetectors. A difference amplifier takes the difference of these output signals to produce a first electrical signal having a polarity and magnitude representing the direction and amount of motion of the cantilever beam. A derivative circuit takes the derivative of the first electrical signal with respect to time to produce a second electrical signal having a polarity and magnitude representing the direction and rate of movement of the cantilever beam. An electrical coil, having a magnet reciprocally movable relative thereto which is linked to the cantilever beam, produces a magnetic force related in polarity and magnitude to the second signal to cause the magnet to resist the vibratory movement of the cantilever beam.

摘要： A laser alignment system includes a transmitter and one or more receivers. The transmitter produces an alignment field by projecting laser energy in a non-planar reference cone, and the receivers locate this reference cone with photodetectors. The laser energy in the alignment field is modulated at 8 KHz and the signals produced by the photodetectors are filtered and amplified to increase the range of the system. Each receiver operates a display which indicates when it is aligned in the reference cone, and it produces an out-of-level indication when the transmitter is not properly aligned.
