Abstract: The present invention provides a method for realizing high stability of micro-nano optical fiber sagnac loop output by means of filter mode control, and belongs to the field of photoelectric detection technologies. In the present invention, the optical filter is combined with the micro-nano optical fiber Sagnac interference structure so as to control the Sagnac in-loop working mode by use of the mode selection characteristics of the filter. In this way, the interference mode is suppressed to better concentrate energy on the working mode, thereby improving the spectrum output uniformity and stability of the Sagnac loop. Further, the reflection and transmission modes of the optical filter do not participate in interference spectrum output and thus the performance of the system will not be affected. By designing and changing the parameters of the optical filter, the output characteristics of the interferometer can be dynamically controlled.

Abstract: The present disclosure discloses an automatic leveling control method for a four-leg support working platform, which comprises the steps: determining the mass center position of the working platform, determining the main bearing quadrant and distinguishing active legs from the driven leg; adjusting the driven leg to weak state, controlling all legs to synchronously actuate for leveling; calculating the limit compensating actuation length of the driven leg, and performing compensating actuation until accomplishing the leveling process. The method is advantageous in: high speed, high robustness, no repeated oscillation. The mass center always stays within the bearing zone of the active legs, thus completely eliminating capsizing risk of the working platform. The compensating actuation of the driven leg ensures there is no weak leg, and hence high attitude and load-bearing stability of the working platform is achieved.
