摘要： Accessories are disclosed for use with a laser tool which may or may not be self-leveling. The accessories include one or more diffraction elements, effective to receive the incoming beam and produce a plane of diverging laser beams. In preferred embodiments the diffraction elements are self-leveling. When the diverging beams are directed against a surface such as a floor, wall or ceiling, a series of discrete spots define a visible reference line useful in construction layout. The spots themselves may each locate the position of a fastener to be installed, for example, by giving the approximately correct spacing for reference of the user. In another embodiment, lenticular arrays are used to create beams which diverge in a plane and overlie one another to form a visible reference line on a wall or other surface. The line preferably is plumb or level and in one embodiment the user can select among two or more arrays to form a plumb or level line of selected length.

The generation of discrete spots rather than a solid line, as would be generated by a cylindrical lens, better allocates laser power by providing brighter, more visible reference elements on the wall or ceiling.

摘要： A quick action bar clamp has provision for mounting an alignment laser instrument on one jaw of the clamp. The mounting provision allows manual pointing of the laser to facilitate projecting a level line or plane of light with a self-leveling laser instrument. By engagement of the clamp on a fixed structure such as a column, wall stud or door frame, the operator can quickly bring the laser instrument into its self-leveling range and easily adjust the beam height. The attachment of the laser instrument to the clamp is via a threaded rod or a magnetic attachment retention. An L-shaped magnetic attachment can be used in another procedure, to connect the laser to the steel slide bar of the clamp.

摘要： An automatic plumb, level and pointing tool uses a visible laser diode to project light beams in two modes through two windows. In the first mode of operation, the unit is able to project a plumb-up beam and a level beam of light while resting on a surface which is as much as five degrees out of level. In the second mode of operation the unit is able to project two orthogonal beams of light both approximately in the horizontal plane for aligning one or more reference lines. An accurate, low cost method of generating level and plumb beams and planes of light is disclosed. One method uses an approximately leveled platform combined with a weak optical correction. The approximate leveling is done using a single wire or coil spring pendulum element which allows the platform to level itself to within a small fraction of true level, and remaining correction is provided by a weak negative lens or a weak reverse telescope. In alternative embodiments, all leveling is accomplished using a very flexible coil spring as a pendulum element, or a chain link connection in combination with such a spring. Several accessories are disclosed for use with the laser tool.

摘要： A system for checking alignment of laser beam projecting instruments, and for enabling accurate calibration of an instrument, includes a high resolution video camera positioned to receive a laser beam from the instrument. The spot from the detected laser beam is compared on a video monitor to a spot or target position showing the location corresponding to accurate alignment of the beam. Multiple orthogonal beams from an instrument may be directed to the same video sensor using mirrors. By use of the described system the need for long beam paths to check beam alignment accuracy is avoided.

摘要： A plumb laser beam generator includes an internal self-leveling feature to assure the projection of a substantially plumb beam despite tilt of the instrument's housing. Tilt compensation is achieved in preferred embodiments using the angular deflection of a spring due to gravity along with the compensating angular magnification of a telescope which moves pendulously by support on the spring. A laser diode of the instrument is mounted fixedly in the housing, and the telescope resides above the diode and collimating optics, the telescope either hanging by a spring or supported at its base by a spring. The pendulous telescope preferably is motion-damped and includes motion limiting and shock absorbing devices to prevent damage due to sudden acceleration or dropping.

摘要： The present invention relates to the efficient and cost-effective generation of two co-linear laser beams for the purpose of alignment, particularly in the construction industry. The unequal divergence of the light from a typical laser diode produces a beam of elliptical cross section. Two roughly equal co-linear beams of light can be generated by reflecting the collimated elliptical beam from two mirror surfaces at 90.degree. to each other or a single element dividing the elliptical beam in two. Techniques are described for generating offset parallel beams, and for correcting for inherent knife-edge diffraction effects due to division of the beam.

摘要： A system which is preferably employed in a laser alignment instrument produces up to five orthogonal beams from a single laser diode beam. In one embodiment the optics take advantage of the elliptical shape of the beam from a laser diode which when collimated produces a plurality of orthogonal beams by reflection off a plurality of 45.degree.-angled reflective surfaces intercepting outer portions of the beam. In one preferred embodiment a solid reflective element was four 45.degree.-angled facets to produce four beams from outer portions of a preferably non-elliptical beam, and a fifth orthogonal beam is produced by transmission of a central portion of the beam through the element. The element can be solid glass, or it can be glass or other material with a central hole.

摘要： A system preferably in the form of an accessory module corrects for tilt angles of a distance measuring laser projecting instrument. The housing of the module includes a compensating mirror mounted on a pendulum which bends with tilt angle by one-half the amount of the housing tilt, so as to reflect the outgoing beam to truly horizontal. In a preferred embodiment a fixed mirror is also included so that the distance measuring instrument can be laid or held approximately horizontally so that its generally horizontal beam is first reflected by the fixed mirror up to the pendulous compensating mirror. The distance measuring instrument preferably has an internal correction to subtract the additional optical path length induced by the use of the accessory module. This may be activated by a switch on the module or automatically when the module is attached to the distance measuring instrument.
