Title:
DEVICE FOR MEASURING LIGHT REFLECTION
Document Type and Number:
Japanese Patent JPH09206283
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve measurement accuracy by forming at least a light transmission site in a contact face from a lot of rigid light guide elements and optically connecting the whole light guide elements to a specified light transmitter in a device for measuring light reflection on the skin. SOLUTION: A measuring head 1 having a contact face 3 is brought into contact with an interface 5 of a test target 6 and a light is irradiated from a light irradiation means 7 having a light transmitter 20 to the test target 6 through the contact face 3 and the interface 5. The light emitted from the test target 6 in this light irradiation is detected by a detecting means 8 having a light receiver 21, and the detected signal is transmitted to a signal processing and evaluation unit 2. The contact face 3 is provided with optically transparent light transmission sites 13, 14 (14a, 14b), the respective light transmission sites 13, 14 are formed from a lot of (at least 100) rigid light guide elements and this constitution improves stability of the measurement.
