Abstract: An apparatus and method are provided for measuring the included angle of a reflective cone (10) between opposite sides of the reflective cone (10). The apparatus includes means for illuminating the curved surface of the reflective cone (10) with a collimated beam of light (12), the beam of light being generally parallel to the axis (16) of the cone (10). A lens (18) receives directly a portion of the light (12) reflected from a first side (20) of the cone (10), and focuses the portion of the light (12) so received in a reference plane. A retro-reflective mirror arrangement (26, 28), positioned on the side of the cone (10) opposite the lens (18), receives directly a portion of the light (12) reflected from a second side (30) of the cone (10) and redirects the light (12) to the lens (18) in a direction parallel to the light reflected from the second side (30) of the cone (10). The second side (30) of the cone (10) is opposite to the first side (20) of the cone (10). A light detection arrangement at the focal point of the lens (18) displays the light received by the lens (18), whereby the spacing between the light received from the retro-reflective mirror arrangement (26, 28) and the light received directly from the cone (10) is related to the included angle between the first (20) and second (30) sides of the reflective cone (10).

Abstract: A transmitter (10) for an alignment system in which a field (14) of electromagnetic radiation is propagated in a non-planar reference cone is disclosed. The transmitter (10) includes a chassis (16) with a source (27) fixed to the chassis (16) for providing a beam of electromagnetic radiation and an optical deflector (102, 102′, 171, 182, 198, 226, 235, 260 or 277) which converges toward the source reflects the beam into an omni-directional cone of radiation (14). A flexible support (105, 105′, 105˝, 170, 173, 184, 200, 228, 237 or 267) having an omni-directional stiffness supports the optical deflector (102, 102′, 171, 182, 198, 226, 235, 260 or 277) in the beam to reflect the reference field (14) in a level orientation when the chassis (16) is level. An angular error in the orientation of the chassis (16) from level results in the optical deflector (102, 102′, 171, 182, 198, 226, 235, 260 or 277) deviating from the aligned position to maintain the reference field (14) in the level orientation. Damping of the deflector (102, 102′, 171, 182, 198, 226, 235, 260 or 277) is also provided for and sensors (132, 136, 240, 241 or 242) detect when the angular error of the chassis (16) has exceeded an allowable amount.

Abstract: A laser alignment system includes a transmitter (1) and one or more receivers (2). The transmitter (1) produces an alignment field by projecting laser energy in a non-planar reference cone, and the receivers (2) locate this reference cone with photodetectors. The laser energy in the alignment field is modulated to 8 kHz and the signals produced by the photodetectors are filtered and amplified to increase the range of the system. Each receiver (2) 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.

Preferably, the optical target (118) has a green tint which filters the green light from ambient light. The optical target (118) may also have reference indicia (200) thereon to assist in aligning the target (118) with the reference beam of light (106).

Abstract: Apparatus (100) operable in accordance with the method of the present invention for measuring the angle of incidence of a light beam or plane (108) relative to level comprises a photodetector array (102) for sensing the light and a level mirror (104) preferably comprising a pool of mercury. Optics (112, 114, 118, 120) 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 (106) 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 (108) from level.

Abstract: A method and apparatus are provided for controlling the working depth of a bucket for an excavating machine (100) having an outreach boom (102) which is pivotally attached at one end to the machine, a downreach boom (108) pivotally attached to the opposite end of the outreach boom, a digging bucket (112) pivotally attached to the end of the downreach boom opposite to that to which the outreach boom is attached, and hydraulic power cylinders (116, 118, 120) for moving the pivotally interconnected elements. A laser beam (126) is projected at a reference height and a beam sensor (128) mounted on the outreach boom (102) of the machine detects the beam (126) by means of a plurality of individual sensor locations. The angular orientation of the downreach boom (108) relative to vertical is detected by an angle sensor (134, 136, 138, 140, 142) and a microprocessor controller (150) connected to the beam sensor (128) and the angle sensor (134, 136, 138, 140, 142) repetitively defines, as a function of the angular orientation of the downreach boom (108), one of the plurality of individual sensor locations (C1-CX) as an on-grade sensor location. The microprocessor controller (150) compares the defined on-grade sensor location to the sensor location having detected the laser beam to generate an outreach boom adjustment signal representative of the movement of the outreach boom (102) which is required to maintain the bucket (112) on-grade as the downreach boom (108) is pivoted with respect to the outreach boom (102).

Abstract: A compact, laser diode pumped, high efficiency, solid-state laser comprises an output coupler mirror (182) forming a front end of a laser cavity. A back end of the laser cavity is formed by a rear mirror (172) through which emissions from a laser diode (162) pass for pumping a laser chip (174) of stoichiometric lasing material. A frequency doubler chip (176) is positioned immediately adjacent the laser chip to double the frequency of light generated by the laser chip and thereby halve its wavelength. The laser chip is bonded to the frequency doubler chip by coupling material having a refractive index matched to the chips to nearly eliminate reflections at the bonded chip surfaces. Such bonding increases the effective Q of the laser cavity which receives the bonded combination of the laser chip and the doubler chip at a beam waist defined within the laser cavity by means of beam shaping with the laser chip being positioned to receive pumping energy from the laser diode through the rear mirror of the laser cavity. Spiking or peaking of the output laser light is effected by gain switching, phase modulation or by imparting vibratory motion to the bonded combination of the laser chip and the frequency doubler chip.
