Method for dynamically detecting force-induced discoloration film in combination with photoresponse

Abstract

The invention discloses a photoresponse-combined force-induced color-changing film dynamic detection method, relates to the related technical field of record carrier processing, and pre-prepares a force-induced color-changing film through a predetermined anti-counterfeiting preparation strategy to obtain an anti-counterfeiting sample. And activating a universal material testing machine to apply an acting force to the anti-counterfeiting sample, and dynamically monitoring through a combined spectrometer to obtain light response information of the anti-counterfeiting sample under the acting force. Extracting a first spectrum in the light response information, and collecting to obtain a first characteristic parameter set of the first spectrum; and introducing an anti-counterfeiting performance comprehensive evaluation function to evaluate and analyze the first characteristic parameter set to obtain first comprehensive performance. And analyzing the first comprehensive performance to obtain the anti-counterfeiting fitness of the force-induced color-changing film. The technical problems of insufficient dynamic light response monitoring and incomplete comprehensive performance evaluation of a force-induced color-changing film detection method in the prior art are solved. And the adaptability and the detection precision of the anti-counterfeiting film under the mechanical action are improved.
