Abstract
A method of designing a container of a liquid reflection inclination sensor includes a liquid surface calculating step (S) 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 (S) that obtains a light receiving pattern by reflecting a dark field pattern (') irradiated from an imaginary light source (′) on an imaginary mirror plane (9′) having the shape of the liquid surface, and a container adjusting step (S-S) that adjusts a shape of a cylindrical container () for enclosing the liquid by judging whether image accuracy of the light receiving pattern satisfies demanded sensor accuracy.
