Abstract

This invention relates to the field of signal technology, specifically disclosing a multi-channel phase-synchronous electronics system suitable for Bolometer detectors, comprising: an excitation module: applying multiple synchronous excitation signals to multiple channels and acquiring the original detection signals; a modulation and demodulation module: modulating the original detection signals to generate modulated signals and transmitting them, and demodulating them based on a reference signal to obtain a demodulated signal; an optimization module: when the baseline value exceeds a preset baseline threshold, generating a compensation signal based on the baseline value; applying the compensation signal to the input terminal of the corresponding channel of the Bolometer detector and acquiring a new baseline value, and repeating the above steps; when the baseline values ​​of all channels are within the baseline threshold, outputting the demodulated signal at this time. This invention can effectively improve the data reliability of multi-channel Bolometer detection systems in radiation calorimetry diagnostics.
