Summary: | In the prior art, when a Fourier imaging system is used for imaging, the imaging precision is low; the requirement on the laser light source stability is too high; therefore, the engineering is difficult to reach or the cost is too high; or the imaging timeliness becomes poor due to the fact that the sampling time is prolonged; and the application range of the imaging system is limited. The utility model provides an active imaging system for inhibiting a laser intensity fluctuation image quality degradation effect, laser is divided into a main light beam and an auxiliary light beam through a laser beam splitter, the main light beam is used for scanning a target surface, and the main light beam is reflected by the target surface and converted into a laser echo electric signal so as to obtain a phase closing coefficient; the auxiliary light is used for detecting a light intensity value; and calculating to obtain a light intensity fluctuation proportionality coefficient matrix so as to obtain a light intensity d |
