Abstract

PURPOSE: To make measurement at high-efficiency by giving two parallel planes a rotation which passes through a prearranged position where two parallel planes come parallel with a measuring light and measuring the space of the two parallel planes.
CONSTITUTION: A laser beam 3 from a laser oscillator 21 is projected into between two planes 13, 14 after being enlarged in diameter by means of a collimeter lens body 22. An electronic gun 11 is fixed in a detachable manner on a measurement body 23 and the measurement body 23 is axially supported by a pin 24. The outer edge face 25 having a concentric arc with the pin 24 contacts the friction roller 27 of a motor 26, and the measurement body 23 gyrates at angle θ only to the right and left by the normal and reversed rotation of the motor 26 through the intermediary of the friction roller 27. A certain moment in the middle of gyration, two parallel planes 13, 14 come parallel with a measurement light 3, passing through a prearranged position. Due to the gyration of these two parallel planes 13, 14, the quantity of light of the laser beam 3 passing through the two parallel planes is the maximum when the laser beam 3 is at a position parallel with the two parallel planes 13, 14, and the laser beam 3 is inputted to a sensor 30 placed behind the measurement body 23. An output which changes proportional to an incident light quantity is inputted to a signal processing device 30 from the sensor 30, and is displayed on a display device 32.
