　　As the backbone of the space infrastructure, satellites play an indispensable role in exploring and understanding space, providing communication and navigation services, and carrying out scientific and technological research. The accuracy of satellite shell thickness measurement is closely related to the safety and stability of space infrastructure, and has always been one of the key indicators to measure the performance of satellite shell manufacturing equipment. In recent years, with the continuous development of space technology and the application of new materials, the accuracy requirements of satellite shell thickness measurement have become more and more stringent, and the technology of thickness measurement has become more and more mature. In this paper, the development of satellite shell thickness measurement technology is summarized from three aspects: online measurement technology, offline measurement technology and non-destructive testing technology.

　　傳統的衛星殼厚度測量技術主要以離子束切割技術為主，以精密測量儀器來測量衛星殼的厚度，并對其進行精確的測量。然而，這種技術存在一些缺陷，如對衛星外殼表面的質量要求較高，且制造成本較高。為了解決這些問題，科學家們開發出了一種新的衛星殼厚度測量技術，即在線衛星殼厚度測量技術。

　　非破壞性測試技術是目前衛星殼厚度測量技術中應用最為廣泛的一種技術。非破壞性測試技術主要應用于已制造好的衛星外殼的厚度測量，通過對衛星殼的物理和力學特性進行測量和分析，可以對衛星殼的厚度進行精確測量。非破壞性測試技術主要應用于激光測厚儀、超聲波測厚儀和成像技術等技術。

　　Non-destructive testing technology is currently the most widely used technology in satellite shell thickness measurement technology. Non-destructive testing technology is mainly used in the thickness measurement of manufactured satellite shell. By measuring and analyzing the physical and mechanical characteristics of satellite shell, the thickness of satellite shell can be accurately measured. Non-destructive testing technology is mainly used in laser thickness gauge, ultrasonic thickness gauge and imaging technology.
