Title: Instrument for measuring area, configuration and the like of contact surface by optical contact method
Inventor: TANAKA YOJI
IPC: G01N21/84
Filed: 1990-11-28
Abstract: PURPOSE:To increase the lightness of the contact surface of an object to be measured and improve the accuracy of picture image processing by introducing light from the marginal side face of a glass plate and making a portion in which the object to be measured is brought into contact with the bottom surface of a stage a irregular reflection light source. CONSTITUTION:In the stage 12 of an instrument, one end 14A of a light guide member 14 made of optical fibers which is opposed to the marginal end of one end 13A of a transparent or translucent glass plate 13 is made a light guide portion. In the light guide portion, a wide light beam is introduced to the inside of the glass plate 13 from its one end 13A so that an angular aperture becomes approximately 50 deg. - 60 deg. and an incident angle with respect to the inside boundary surface of the glass plate 13 becomes approximately 55 deg. - 60 deg. larger than the critical angle (approximately 42 deg.) of light proceeding from the inside of glass toward the outside air. Therefore, the light beam is subject to multiple total reflection and emitted from the opposite side end face of the glass plate 13. By mounting such a light guide portion to the glass plate 13, when an object to be measured is brought into contact with the lower surface of the glass plate 13, irregular reflection is generated on the contact surface of an article due to evanescent wave due to partial invading light from the inside of the glass into the air.
