AB - REVIEWS AND REPORTS OPTICOMECHANICAL INSTRUMENTS FOR CONTROLLING THE LINEARtTY AND COAXIALITY OF LARGE-SIZE PRODUCTS E. I. Rozenberg Translated from Izmeritel'naya Tekhnika, No. 7, pp. 57-58, Iuly, 1963 The sighting and step-by-step methods are the most commonly used optical methods designed for testing the linearity and coaxiality of large-size products. The telescope is mounted at one end or near the tested surface in measuring tinearity by means of the sighting method. The luminous marker is displaced along the tested durface and at certain points the displacement of the marker image with respect to the reticule of the telescope is evaluated. Measurements are made by means of the telescope reticule scale (marker scale) or a special optical micrometer. Fig. 1. Fig. 2. The method of measuring the coaxiality of holes is similar to that for measuring nonlinearity, with the excep- tion that the marker in a special mounting is placed consecutively into the tested holes instead of being displaced along the surface. Autocollimation tubes and mirrors or telescope tubes and collimators are used in the step-by-step method. The majority of existing instruments have facilities for measuring both by the sighting and step-by-step method. Instruments produced by several foreign firms [Zeiss (GDR),
