Determination of the maximum distance of video recording for measuring the displacements of mechanical objects in an optical way, using reflective holographic test objects
The article discusses a quasi-contactless optical method for measuring the vibration frequency of mechanical objects using holographic test objects. The main objective of the work is to find a combination of the optimal illumination parameters, the size of the test objects, the settings of the video camera, at distances from the lens to the moving object close to the maximum possible for measuring movements in the considered way.
