Abstract
PURPOSE: To accomplish a highly accurate measurement with easy by utilizing reflected light from a stripe patterned body.
CONSTITUTION: A part of the surface of an object 10 to be measured is fitted with a stripe patterned body 11 which comprises a printed matter or a sheet-shaped matter having the strips almost equal in the width and space to the thickness of laser beams 23 and 24. A laser device 20 connected to a digital signal processing device is arranged facing the body. Laser beams 23 and 24 respectively from the first laser 21 and the second laser 22 different by 90° in the phase therefrom is irradiated on the striped body 11 to convert the modulated reflected signal according to the vibration of the object 10 to an electric modulated signal, which is inputted into the digital signal processing device 100 to count the modulated signal as converted to pulses. The discrete of value is indicated on a display 30. This enables the highly accurate measurement regardless of the quality, shape, composition, temperature, magnetism and the like of the object.
