为了对大型或复杂的物体进行测量,至少需要两张甚至三张全息干板布置在相对于物体的适当位置上。本文提出了一种专门的全息光路系统,可使实验装置的布置工作量减少,并使光路系统的稳定性提高。对一台实际的铣床(高1.6m,宽1.1m)在机械加工车间的普通地面上用连续波激光器成功地拍摄了全息照相。从几何学观点推导了一组实用化的定量分析方程组。分析工作是基于以照明光源为原点的物体外形直线坐标值和三张干板观测点的坐标值。把物体测点的坐标、相邻测点的距离、
In order to measure large or complex objects, at least two or even three holographic plates are required to be placed in position relative to the object. In this paper, a special holographic optical system is proposed, which can reduce the workload of the experimental apparatus and increase the stability of the optical system. An actual milling machine (1.6 m high, 1.1 m wide) succeeded in taking a hologram on a continuous ground laser on a normal ground in a machining shop. A set of practical quantitative analysis equations is deduced from the perspective of geometry. Analysis is based on the light source as the origin of the shape coordinates of the object coordinates and three dry plate observation point coordinates. The coordinates of the object measuring point, the distance between adjacent measuring points,
