description The invention provides a pyroelectric IRFPA image acquisition method, which comprises the following steps that: a modulation signal data output end of a chopper is connected with a modulation signal data input end of a pyroelectric TRFPA device, and a synchronization signal data output end of the chopper is connected with a synchronization signal data input end of a driving module; a driving signal data output end of the driving module is connected with a driving signal data input end of the pyroelectric TRFPA device, and a sampling control signal data output end of the driving module is connected with a sampling control signal data input end of the NI data acquisition card; and an image signal data output end of the pyroelectric TRFPA device is connected with an image signal data input end of the NI data acquisition card. Through the acquisition method, judgment and demodulation processing of a bright field and a dark field are ensured, accurate acquisition of pixels corresponding to a device is realized, th
