摘要： A laser system for surveying, which comprises a laser light source unit, an optical system for irradiating a laser beam from the laser light source unit toward a given direction, whereby said laser light source unit is at least thermally isolated from the optical system, and the laser beam from the laser light source unit is guided toward the optical system by an optical fiber. Because the laser light source unit, or at least a heat generating portion of the light source unit is isolated from the optical system, no influence of heat from the laster light source unit is exerted on the optical system, and it is possible to prevent decrease of accuracy due to heat and to maintain the laser system for surveying in a condition to provide measurement at high accuracy.

摘要： In a light-wave distance meter, a light source device emits reference modulated light beams from multiple spatially-separated light emitting areas, an optical means radiates a light beam derived from the multiple modulated light beams to the target of measurement, a light beam reception means receives the reflected return light beam from the target and converts it into an electrical pulse signal, and a distance measuring means calculates the distance to the target based on the time difference between the light beam emission and the return light beam reception. The low coherence and high intensity light beam produced by the light source device enables the extension of the maximum measurable distance.

摘要： An optical distance measuring apparatus having measurement error compensating function for compensating the measurement error due to electromagnetic induction noise which would lower the accuracy in distance measurement. According to the optical distance measuring apparatus of the present invention, the distance from the apparatus to the target is given by the difference in optical path between an "external optical path" to a corner-cube prism, i.e. the external target, and an "internal reference optical path". The measurement error can be cancelled by the periodicity of the measurement error curve and the predetermined length of the optical path extension means. Thus the measurement error can be compensated for and therefore a measured distance value free of measurement error can be obtained from the distance measuring apparatus.

The scanning laser ophthalmoscope comprises an image generating unit that generates first images based on the light reflected from first laser light and second images based on the light reflected from second laser light. An associating unit associates the first images and the second images based on the first laser light and the second laser light parallelly scanned by the scanning unit. A displacement calculating unit calculates displacements between images regarding multiple first images. The position matching unit matches the positions of multiple second images based on the processing results from the associating unit and the displacements. The superposing unit superposes the multiple second images that have undergone the position matching. The display unit displays an image obtained by superposing the multiple second images.
