| Outline of Final Research Achievements |
We developed a non-contact and simple method for measuring the inclination angle and the diameter of slender deep hole in castings such as cylinder block for automotive products. To measure the distance to the measurement surface, three laser beams are radiated perpendicularly from the sensing probe. Then the scattered lights are led to a prism and an image conduit in the probe and finally focused on an external image sensor. As the result of experiment, we confirmed to be able to measure the distance with high degree of accuracy even if the measurement surface is inclined. Consequently, the diameter of deep hole can be measured even if the sensor probe is eccentrically located.
