Abstract
A Raman spectrum detecting method and electronic device are disclosed. In one aspect, an example method includes detecting and obtaining a first Raman spectrum signal of a package. A second Raman spectrum signal of the object is detected and obtained with the package. The first Raman spectrum signal is successively subtracting from the second Raman spectrum signal to obtain a series of third Raman spectrum signals with package interference eliminated. Information entropies of the third and first Raman spectrum signals are calculated and compared with information entropy of the first Raman spectrum signal. Information entropies of third Raman spectrum signals greater than the first Raman spectrum signal are set into an information entropy sequence to be selected, and a minimum information entropy from the sequence is selected. The third Raman spectrum signal corresponding to the minimum information entropy is used as an optimized Raman spectrum signal with package interference eliminated.
