Two-axis inclinometer
First Claim
Patent Images
1. An inclinometer for measuring inclinations or changes in inclination in two mutually perpendicular directions, comprising:
- a geometrical figure arranged on a carrier;
a linear sensor array;
an inclination-sensitive ray-deflecting device, said inclination-sensitive ray-deflecting device being a liquid prism; and
a light source which illuminates said carrier for projecting said geometrical figure onto said linear sensor array via said inclination-sensitive ray-deflecting device, wherein said geometrical figure includes a plurality of lines having differing line thickness forming individual angles arranged one behind another to form a herringbone pattern, said geometrical figure being arranged with respect to said light source and said sensor array such that both sides of at least one of said plurality of angles intersects said array at two points.

Abstract
A two-axis inclinometer having an inclination-sensitive ray-deflecting device is described, via which a geometrical figure having at least one angle is projected onto a linear array. In addition to providing high resolution, a large measurement range is also opened up by the special arrangement and configuration of the geometrical figure. X-, Y- and overlapping inclinations can be determined simultaneously using the described inclinometer.
