| 摘要 |
The invention discloses a floated gimbal instrument platform providing a stabilized mount for an optical instrument. The invention comprises: a vehicular mounted base; a spherical hollow sealed outer vessel 16 fixed to the base with a first optically transparent viewing port 19; a spherical hollow sealed inner vessel 17 assembly centrally positioned in the outer vessel comprising a second optically transparent viewing port 23 aligned with the first optically transparent viewing port, and an optical instrument 20 mounted within the inner vessel assembly and optically aligned with the first transparent viewing port; an optically transparent suspension fluid 18 separating the inner and outer vessels and having a density substantially equal to the spherical inner vessel assembly; means 26 to assist in centrally positioning the inner vessel assembly within the outer vessel; means (eg. coils or gyroscopes) to detect misalignment of the second transparent viewing port with the first transparent viewing port; and means to rotate the inner vessel assembly within the optically transparent suspension fluid; wherein detected misalignment between the first and second transparent viewing ports is corrected by rotating the inner vessel assembly. The centre of gravity of the inner vessel assembly is located at the physical centre of the inner vessel assembly and the inner vessel assembly floats in the optically transparent suspension fluid in neutral buoyancy. |
