【摘要】<正>Topological charge represents mode of orbital angular momentum(OAM)of light.The function to measure the mode distribution of OAM light,named OAM complex spectrum analyzer,is essential to characterize OAM performance.Although there are lots of works to detect or sort OAM modes,it is difficult to measure the amplitude of OAM modes quantitatively and
