Studies on the Optical Profilograph (I)

Turning out of the Optical Profilograph and its Accuracy

Abstract

In order to improve the accuracy of the Mechanical Profilograph, authors have made the Optical Profilograph which cuts the plow bottom with a plane of light and takes photograph of it.
The Optical Profilograph proved to have following merits: 1) It is more precise in measuring plow shape than the former Mechanical Profilograph. Its measuring error is estimated to be less than 1%. 2) man can easily measure slat moldboard plow with it. 3) making use of it, man can measure 3-dimensional curved line with optical sweeping method.
