Title:
CONTACT STATE DETECTION DEVICE, CONTACT STATE DETECTION METHOD, COMPUTER PROGRAM FOR CONTACT STATE DETECTION, ELECTRICAL CONDUCTIVITY MEASUREMENT SYSTEM PROVIDED WITH CONTACT STATE DETECTION DEVICE, AND ELECTRICAL CONDUCTIVITY MEASUREMENT METHOD INVOLVING CONTACT STATE DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2012/008484
Kind Code:
A1
Abstract:
Disclosed are a contact state detection device with a simple structure capable of accurately detecting, without damaging a contact body (such as a probe) or a contacted body, the pressing state of the contact body pressing on the contacted body; also disclosed is an electrical conductivity measurement system provided with the contact state detection device. The contact detection device suitable for an electrical conductivity measurement system (100) is provided with a contact body approach unit (123), a probe light source (131), an imaging element (135), and a computer device (140). The contact body approach unit (123) is displaced towards the contacted body (WK) while holding the contact body (110) oriented so as to intersect the contacted surface of the contacted body (WK). The probe light source (131) irradiates light towards the contact body (110) which is displaced towards the contacted body (WK). The imaging element (135) images the illuminated contact body (110) and outputs to the computer device (140) contact body captured image information. The computer device (140) detects the pressing state of the contact body (110) pressing on the contacted body (WK) on the basis of changes in the contact body captured image information.
