description The invention discloses a ternary fluctuation correlation spectrum generation method and device, and the method comprises the steps: carrying out the irradiation or excitation detection of a sampling point through a ternary fluctuation correlation spectrum system, outputting three paths of level signals through three avalanche diode single photon detectors, and carrying out the collection and analog-to-digital conversion through a data collection card, thereby generating corresponding three paths of photon information matrixes; the method comprises the following steps of: acquiring a three-path photon information matrix, performing sparse data extraction on the three-path photon information matrix by adopting an exponential interval method to generate a sparse matrix of corresponding three-path photon information, and performing ternary correlation calculation on the sparse matrix by adopting an optimization algorithm based on a graphic processing unit (GPU) according to a ternary correlation function calcula
