Abstract : The report covers the engineer tests and evaluation of a stereo point marking instrument, an instrument for analytical triangulation to mark points and transfer these points on photographs with large changes in scale and format size. The instrument has a marking accuracy of better than 2 microns and has a high operating speed; also, it has flexibility with many ease-of-operation features because of the variable parameters of optics, marking dies, and sizes of photographs.
