Title:
MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/151194
Kind Code:
A1
Abstract:
An irradiation element (212) radiates electromagnetic waves. A movable reflecting element (216) changes the course of electromagnetic waves (emitted waves) heading to the outside of a measurement device (200) and the course of electromagnetic waves (reflected waves) reflected by an object and returned to the measurement device (200), and the orientation of the movable reflecting element (216) is also variable. A variable-refractive-index element (218) further changes the course of the reflected waves, the course of which is changed by the movable reflecting element (216). The variable-refractive-index element (218) is positioned between the movable reflecting element (216) and a reception element (214) on the course of the reflected waves, and the refractive index of the variable-refractive-index element (218) is variable. The reception element (214) receives reflected waves that reach the reception element (214). A first control unit (222) changes the orientation of the movable reflecting element (216) on the basis of the time elapsed from a reference time point. A second control unit (224) changes the refractive index of the variable-refractive-index element (218).
