全息摹象法即用全息摄影术钩画或测量复杂的曲面的方法,可在汽车工业中得到新用途。在美国通用汽车公司,由物理学家组成的一个三人小组,用全息摄影术,发明了一种方法,可以从设计者的模型上取出具体的测量数据,绘制冲模的工程图纸。 在操作中,用大功率、脉冲式的红宝石激光器作为照明光源,全息摄影机把模型的全息图拍在底片上。用另一只激光器照明显影后的全息图,在空间投 Holographic Means, the method of hooking or measuring complex surfaces with holography, finds new uses in the automotive industry. At General Motors, a three-person team of physicists invented a method using holography that takes concrete measurements from the designer’s model and draws the drawing of the die. In operation, a high-power, pulsed ruby ​​laser was used as the illumination source, and the hologram took the model’s hologram on the film. Illuminate the developed hologram with another laser and cast in space
