The invention discloses a Fresnel holographic reproductive image controllable amplification reconstruction system and method. The system comprises a laser beam, a beam expander, a first beam splitter, a lens, a diffraction object, a second beam splitter, a reflector, a microscope objective, a pinhole filter, a collimating lens, a holographic recording surface, a CCD camera and a computer. The laser beam, the beam expander, the first beam splitter and the reflector are coaxially arranged, the diameter of the laser beam emitted by the laser is expanded by the beam expander, then the laser beam is divided into two beams of light through the first beam splitter, one beam of light irradiates a diffracted object through the lens, and after being scattered, the beam of light passes through the second beam splitter to serve as object light to reach a holographic recording surface; the other beam of light is emitted by a reflector and then is changed into plane light through a microscope objective, a pinhole filter an
