The present application provides a compound refrigeration system for a heat pipe of a supergravity centrifuge. The compound refrigeration system for the heat pipe of the supergravity centrifuge includes a rotor rotating around a vertical axis, an experimental cabin covering outside the rotor, and a corresponding cooling system. The rotor is provided with a shaft part which is in running fit with the experimental cabin. The shaft part is provided with a shaft top end located outside the experimental cabin. The cooling system includes a liquid cooling device and an evaporative cooling device. The liquid cooling device comprises a refrigeration source, and a first cooling medium circulating pipeline communicated with the refrigeration source and thermally coupled with a cabin wall of the experimental cabin. The evaporative cooling device includes a condensation chamber arranged outside the experimental cabin, and a heat pipe radiator thermally coupled with the rotor.

The present invention relates to the technical field of optical imaging, in particular to an optical field imaging system based on dual galvanometer scanning, comprising: an imaging unit, a galvanometer unit, a microlens array, a relay system and a camera which are arranged successively along a transmission direction of an optical path. The imaging unit is used for optically imaging a sample or a scenario. The galvanometer unit is composed of two non-parallel two-dimensional galvanometers which deflect beams in two directions of X axis and Y axis respectively, so that an input beam is perpendicular to an output beam. After the beam outputted by the galvanometer unit passes through the microlens array and the relay system, the beam is collected by the camera to obtain the stack information of optical field images.
