Non-contact dynamic detection method of solid contour shape

摘要

The present invention relates to a method for carrying out the purpose of measurement of wear that occurred (1,1a) solid, especially non-contact dynamic detection of the profile of the solid (1,1a) of (P). One beam is irradiated on the surface of solids (1), the surface of the solid (1,1a) at least has been expanded linear beam one band of (3) at least provided is generated by (2) laser device It is focused by (5) in an imaging device arranged to keep the reference distance a fixed (B) in the laser device (2), the motion velocity solid (1) the reflected light (RL) is detected by (6) light receiving element area type at a high frequency compared to (v), then, from the signal output (6) the light receiving element, a data processing device, the triangulation angle (φ) measured value profile of the (P) as a linear combination of the correction value on the basis of the reference distance and (B), and is determined according to (v) moving speed of the solid and the use of trigonometric relationship (1) The obtained and stored as a profilogram (PG) in the data processing apparatus.
