Miniature hyperspectral instrument system and use method thereof

The invention relates to a miniature hyperspectral instrument system and a use method thereof. The miniature hyperspectral instrument comprises a miniature hyperspectral instrument body and a mobile terminal. The miniature hyperspectral instrument body uses a multi-channel photosensitive element to acquire spectral information of a to-be-tested object, wherein the spectral information includes first spectrum information for video previewing of the to-be-tested object and second spectral information including spectral collection data of the to-be-tested object; and video data and the second spectral information are transmitted to the mobile terminal by wireless transmission and a video image corresponding to the video data and the spectral image processed by the second spectral information are displayed on the display screen of the mobile terminal. According to the invention, the miniature hyperspectral instrument collects and preprocesses the spectral information of the to-be-tested object and data exchanging
