Abstract
An infrared light source radiates infrared light. An ATR prism receives, on a first end face, the infrared light radiated from the infrared light source, causes the received infrared light to pass therethrough while repeating total reflection off a second end face and a third end face, and emits the infrared light that has passed therethrough from the third end face. An infrared photodetector detects the intensity of the infrared light emitted from the ATR prism. Strain sensors, which are contact sensors of one type, are attached to the ATR prism and configured to detect a contact state between the ATR prism and a measurement skin.
