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 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.

Abstract: A position sensing system calculates the X-Y coordinates of a point (12) using triangulation and determines the direction in which the point (12) is moving. The triangulation calculation is based on the coordinates of at least three retroreflective elements (18) spaced apart from each other around the periphery of a two-dimensional coordinate frame, and the measured angles between the lines projected radially outward from the point (12) to each of the retroreflective elements (18). The accuracy of the measured angles is achieved by using a rotating member (30) supported by dedicated hardware and controlled by software. The member (30) rotates with a beam of light (16) generated by a light transmitting and detecting device (14) positionable at the point (12). The light transmitting and detecting device (14) receives the beam of light reflected back from the retroreflective elements (18) and generates an output signal in response thereto. A computer (22) processes the output signals for use in calculating the X-Y position of the point (12) and the orientation of the light transmitting and detecting device (14) when it is positioned at the point (12).

Abstract: An orthogonal light plane generator is associated with a primary light plane generator (100) to convert a portion of a first light plane (108) projected by the primary light plane generator (100) into a second light plane (110) substantially orthogonal to the first light plane. The orthogonal light plane generator comprises a diverter (102) which defines three or more reflecting surfaces for receiving a portion of the first light plane (108) and redirecting that portion as the second light plane (110). The three or more reflective surfaces are oriented relative to one another such that tilting of the orthogonal light plane generator is compensated to maintain the orthogonality between the two light planes. Tilting about one axis results in offset of the second light plane and tilting about a second axis orthogonal to the first results in a shifting of the sector (112) within which the second light plane is projected, but tilting about either axis does not affect the orthogonality between the planes (108,110). Preferably the three or more reflective surfaces are defined by one or more prisms (104,106) formed of an optical material having an index of refraction which enlarges the sector angle encompassed by the second light plane when compared to mirrored surfaces supported within air. The performance of the diverter can be further enhanced by optical devices positioned at its input and/or output. The optical devices can be one or more conventional lenses or angled wedges of optical material.
