Multi-channel ultrasonic detection device and detection method based on odd-even anti-phase coding

The invention relates to a multi-channel ultrasonic detection device and detection method based on odd-even inverted coding. The ultrasonic transducer array comprises ultrasonic transducers which are sequentially arranged along the surface of a sample to be detected, so that an ultrasonic detection channel is formed based on one ultrasonic transducer; the detection processing device is adaptively and electrically connected with the ultrasonic transducers in the ultrasonic transducer array, and when the ultrasonic transducer array is used for carrying out ultrasonic detection on a sample, the ultrasonic transducers configured with a plurality of ultrasonic detection channels simultaneously transmit ultrasonic signals to the direction of the sample; and for a plurality of ultrasonic detection channels for transmitting ultrasonic signals, configuring the coding state of the ultrasonic signals of adjacent ultrasonic detection channels to be in an odd-even anti-phase coding state. According to the invention, multi
