| description | The invention discloses a Raman detection head device suitable for in-situ detection of brain tissues, relates to the technical field of optical detection, and solves the technical problems of unstable imaging and high positioning control difficulty caused by uneven surfaces of active tissues. The device comprises a laser, a double-color high-reflectivity mirror, a convergence mirror assembly, a window lens, a micro-nano particle layer and an optical fiber Raman spectrometer, the micro-nano particle layer is manufactured on the contact surface of the window lens and the tissue; a laser device emits a laser beam, the laser beam is reflected to a convergence mirror assembly through a double-color high-reflectivity mirror, the laser beam is converged by the convergence mirror assembly, the laser beam is enhanced under the action of a Raman signal micro-nano particle layer which is focused by the micro-nano particle layer and induced by focused laser, and a reverse Raman scattering signal which is generated at th |
