Other AbstractThe invention, which belongs to the field of the microwave radiation thermo-acoustic measurement field, particularly relates to a radiation field spatial distribution measurement apparatus and method of a thermo-acoustic effect. The apparatus comprises a microwave radiation module, an ultrasonic sensor array, a data acquisition and preprocessing module, a motion control module, a container device, a to-be-measured sample, and an image reconstruction module. The ultrasonic sensor array is arranged inside the container device and is used for detecting an ultrasonic wave generated by the to-be-measured sample; the data acquisition and preprocessing module is connected with the ultrasonic sensor array of the 2-512 path array and is used for carrying out filtering and amplification processing on an ultrasonic s signal and carrying out data collection and storage; the image reconstruction module connected with the motion control module and the data acquisition and preprocessing module receives a synchronous signal of the microwave radiation module and controls the position of the ultrasonic sensor array and a time sequence of the data acquisition and preprocessing module. According to the invention, a space distribution situation of a pulse microwave radiation field can be analyzed accurately by a thermo-acoustic image of an absorber with a known absorption coefficient.
