Title: Automatic inclination compensator and inclination detector
Inventor: OTOMO FUMIO
IPC: G01C9/18
Filed: 1994-07-22
Abstract: PURPOSE:To enable common use of the apparatus both for horizontal and vertical states by providing a reflection mirror or the like to make a luminous flux reflected on a free liquid surface reflect to the free liquid surface again. CONSTITUTION:A luminous flux 13 from a light source 14 is admitted into a transparent liquid 1 from an incoming/outgoing window 4 and reflected on a free liquid surface 3, a reflection mirror 6 and then, the liquid surface 3 again. The reflected luminous flux 30 is emitted from a window 4 to be reflected on a polarizing beam splitter 17 and furthermore, reflected vertically with a reflection mirror 19. The liquid surface 3 is always kept horizontal even when the whole of the liquid surface 3 is inclined and the luminous flux 13 is reflected on a horizontal surface. As a result, the luminous flux emitted from a pentaprism 23 becomes horizontal to obtain a horizontal reference line by the luminous flux emitted. When the whole of the liquid surface is inclined by 90 deg., the luminous flux 30 reflected on the liquid surface 3 is reflected on a reflection mirror 8 and on the liquid surface 3 again to be emitted from a window 5 and reflected horizontally with reflection mirrors 18 and 19. This enables the surface the luminous flux irradiated being rotated with a prism 23 to form a fixed vertical reference surface constantly.
