Abstract
Official abstract text for this publication.
A contact state detection apparatus which can accurately detect the pressed state of a contact body such as a probe against an object without damaging the contact body or the object includes a contact body approach section, a probe light source, an imaging device, and a computer unit. The contact body approach section holds a contact body in an inclined attitude with respect to a target contact surface of an object, and displaces the contact body toward the object. The probe light source irradiates light toward the contact body which is being displaced toward the object. The imaging device captures an image of the illuminated contact body and outputs contact body captured image information to the computer unit. The computer unit detects the state of the contact body being pressed against the object based on a change in the contact body captured image information.
First claim
Opening claim text (preview).
What is claimed is: 1. A contact state detection apparatus comprising: a light irradiating device which irradiates a region including a deformable portion of a contact body with light, which portion deforms upon contact with an object; an image capturing device which receives light reflected from the contact body and captures an image of the deformable portion of the contact body and outputs contact body captured image information; and a contact state detection device which re…
