摘要： A laser apparatus includes first and second laser rods disposed at both sides of a center point on an optical axis, respectively, first and second concave lenses, for compensating the first and second thermal lenses, disposed at positions which are both sides of the center point on the optical axis and inner sides of the first and second laser rods, respectively, first and second reflection mirrors disposed at positions which are both sides of the center point on the optical axis and outer sides of the first and second laser rods, respectively, a first supporting unit for supporting the first laser rod and the second concave lens such that a distance therebetween on the optical axis is kept to be a constant value, and a second supporting unit for supporting the second laser rod and the first concave lens such that a distance therebetween on the optical axis is kept to be a constant value, wherein the first and second supporting units are relatively movable on the optical axis.

摘要： An apparatus for continuously measuring a gradient of a curved surface at a number of different points thereon is disclosed in which a laser beam reflected at the point to be measured on the surface makes a beam spot on a photo sensor. The photo sensor follows the beam spot while the center of the beam spot and the center of the photo sensor coincide. The displacement between the beam spot from the point subjected to measurement and the beam spot from a reference point on the surface of the photo sensor is proportional to the gradient at the point subjected to measurement. The photo sensor is, for example, a differential type which comprises four photo diodes. The numerical control table is used to determine the positional relationship of the point to be measured with respect to the laser beam and an X-Y recorder is used to follow the beam spot.
摘要翻译：公开了一种用于连续测量其上的多个不同点的曲面的梯度的装置，其中在表面上要测量的点反射的激光束在光传感器上形成束斑。光传感器跟随光束点，而光束点的中心和光传感器的中心重合。来自测量点的光束点与光电传感器表面上的参考点的光束点之间的位移与经过测量的点的梯度成比例。光传感器例如是包括四个光电二极管的差分型。数值控制表用于确定要测量的点相对于激光束的位置关系，并且使用X-Y记录器跟随光束点。
