▎ 摘　　要

NOVELTY - The micro-spectrometer has a core device (1) fixed at a focus of an optical microscope (2) of the entire set of micro-device. An external light source (3) is used to enter the core device. The core device is provided with a laser graphene strip. A cholesteric liquid crystal capsule (4) is placed in the central position of the laser graphene strip. The laser strip is provided with a first laser strip and a second laser strip. The cholesteric liquid crystal capsule is coated on the central position of the laser-induced graphene strip through PVC hose dipping liquid crystal solution. The left and right ends of the laser-graphene strip are respectively adhered with a conductive adhesive tape. The conductive adhesive tape at the left and right sides is connected to a direct current stabilized voltage supply by a lead to control and heat the laser graphene strip. USE - Cholesteric liquid crystal capsule micro-spectrometer used for biochemical sensing, material analysis, high spectrum imaging and light source characterization in scientific and industrial research. ADVANTAGE - The micro-spectrometer is short and fine, the cost is low, it has high sensitivity, and it can realize quick response. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for utilizing cholesteric liquid crystal capsule micro-spectrometer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a cholesteric liquid crystal capsule micro-spectrometer. 1Core device 2Optical microscope 3External light source 4Cholesteric liquid crystal graphene 8Industrial camera
