Abstract

In a process and apparatus for measuring the dimension of at least one object (8) without physical contact therewith, a fine light beam, for example a laser beam (2), is deflected across the object in the direction of the dimension to be measured and the instants in time at which the light beam impinges upon and moves off said object are determined and stored as measurement data. These data are then evaluated, together with reference data relating to the speed of deflection of the light beam, to provide a measure of the dimension. In one example a computerised system operates in a continuous cycle wherein the measurement data are recorded and stored in a first memory during a first cycle, the data is transferred to a second memory in the direct memory access mode, and then during the next cycle the data in the second memory is processed whilst new data is being read into the first memory. A chopper circuit linked to the means for deflection of the light beam, for example a rotary mirror (3), serves both to control the operating cycle and to provide the reference data.
