The power-driven fluid paraboloid generation device for the astronomical telescope is simple in structure, hard to damage, low in cost, durable and good in effect.
Description
Technical field
The present invention relates to resistor, particularly relate to the power-actuated fluid parabola generation device that can be used for astronomical telescope.
Background technology
Liquid telescope mirror utilizes to rotate to make reflective liquid form parabolic shape, the telescope of astronomical observation is carried out in this, as primary mirror, prior art generally uses a cylindrical band rotated to move liquid in rotation, this liquid driven mode, high to the requirement of bearing, a little a little vibrations will make deformation of image, and complex structure, the life-span is low, cost is high.
Summary of the invention
The present invention has invented a kind of power-actuated fluid parabola generation device that can be used for astronomical telescope.
The present invention has following technology contents.
