摘要： Laser rotary irradiating system comprising a rotary irradiating system main unit and object reflectors including at least a first object reflector and a second object reflector. The rotary irradiating system main unit comprises a rotating and irradiating an irradiation light beam toward the object reflectors, a detector for detecting a reflection light beam reflected from the object reflectors and entering the rotary irradiating system main unit via the rotating unit, and a reflection light detection circuit for identifying the object reflectors from an output of the detector. The position and range of the scanning of the laser beam are determined based on the results of the detection, whereby each of the reflection surfaces of the object reflectors is divided into at least two portions, an irradiation position is confirmed by the first object reflector while the scanning position is confirmed by the second object reflector, and an irradiation light beam is irradiated for reciprocal scanning.

摘要： The present invention provides a laser leveling device, which comprises a light emitting unit for irradiating a laser beam, a rotating unit for rotating the laser beam for scanning, and a means for turning off the scanning laser beam so that a spotlike is formed in a specific direction. By forming a reference spot light, and aligning an irradiating point of the spot beam with the reference point, it is possible to install the laser leveling device 1 to the reference point and to perform accurate positioning of the laser leveling device by the scanning line of the laser beam formed on a portion other than the spot.

摘要： A process and apparatus for measuring an axial eye length takes the steps of projecting monochromatic coherent light of which wavelengths are variable onto an eye to be tested, causing an interference between reflected light from a retina of the eye and reference light corresponding to the retina to generate interference signals while reflected light from a cornea of the eye is interfered with reference light corresponding to the cornea to generate interference signals, mixing these interference signals to generate beat signals while varying the wavelength, and measuring an axial eye length based on the beat signals.
