Phase compensation circuit, magnetic induction imaging device and phase compensation method
A phase compensation circuit includes a phase difference voltage detection module configured to process an inputted detection signal and an inputted reference signal, calculate a magnitude ratio or a phase difference of the processed detection signal and reference signal, and then output a first phase difference voltage signal according to the amplitude ratio or the phase difference. A compensation voltage adjustment module is configured to collect an ambient temperature parameter, determine a first compensation voltage corresponding to the ambient temperature parameter according to a corresponding relationship between a preset temperature parameter and a compensation voltage, perform voltage division on a voltage value inputted from a voltage input terminal according to the first compensation voltage, and output a compensation voltage signal; and a A compensation module is configured to compensate for the first phase difference voltage signal according to the compensation voltage signal and output a second phase difference voltage signal.
