Abstract: To eliminate influences of unnecessary reflected light other than a liquid surface in a liquid surface reflection type inclination sensor. In order to attain the object described above, an inclination sensor includes a liquid that forms a liquid surface, an illumination section, a barcode pattern to be illuminated by the illumination section, an optical system that projects the barcode pattern on the liquid surface, a light receiving element that detects the barcode pattern, a storage section that stores a detection image when the liquid surface is removed from an optical path of the optical system, and an arithmetic section that calculates an inclination angle by subtracting the detection image when the liquid surface is removed from a detection image when the liquid surface is present on the optical path of the optical system.

Abstract: A measurement device and measurement method are provided which are capable of measuring the inclination of a measurement target object surface both with a simple configuration and at high speed. The measurement device includes: a rangefinding light emitting section; a rangefinding unit configured to receive reflected rangefinding light; an optical axis deflection section provided on an optical path common to rangefinding light and reflected rangefinding light, and configured to deflect optical axes thereof; a motor configured to cause the optical axis deflection section to rotate; an emission direction detection unit configured to detect a deflection angle and deflection direction resulting from the optical axis deflection section; and a computation controller that measures the inclination of a measurement target object surface with respect to the emission optical axis on the basis of acquired coordinate data on the measurement target object surface.

Abstract: A method of designing a container of a liquid reflection inclination sensor includes a liquid surface calculating step (S1) that calculates a shape of a liquid surface of a liquid in a horizontal direction “x” and a vertical direction “y” by utilizing the Young-Laplace formula and the hydrostatic pressure formula, the liquid surface formed on a plate extending vertically and infinitely with respect to a horizontal part of the liquid surface, an optical simulation step (S2) that obtains a light receiving pattern by reflecting a dark field pattern (4′) irradiated from an imaginary light source (2′) on an imaginary mirror plane (9a′) having the shape of the liquid surface, and a container adjusting step (S3-S4) that adjusts a shape of a cylindrical container (10) for enclosing the liquid by judging whether image accuracy of the light receiving pattern satisfies demanded sensor accuracy.
