ABSTRACT:
A method and apparatus for optical measurement of the dimension of an object by allowing a ray of light that preserves its direction to sweep across a photoelectrical transformer through a screen placed in front of same. The screen comprises alternate non-transparent and transparent fields such that the photoelectrical transformer receives light pulses. The object to be measured is placed in front of the screen such that it prevents access of the light ray onto the screen and, accordingly, to the photoelectrical transformer within an area corresponding to the dimension to be measured. The received light pulses are converted into electrical pulses, on the basis of whose number it is possible to calculate the dimension to be measured. The screen is divided into a number of component screens with equally divided area arrangements, placed parallel and overlapping each other, the light pulses received from said component screens being sensed and counted separately for each component screen.
