AI Technical Summary
Due to the coherence of incident light, existing optical systems have problems such as speckle, interference fringes and diffraction fringes in imaging, which affects the imaging resolution.
Using a mirror array, the adjustment component connects a plurality of first mirrors to the first base and adjusts the distance between the first mirror and the first base, so that the distance between the plurality of first mirrors and the first base is different, so as to adjust the optical path of the light beam reflected by the first mirror, and realizes that the light path of the reflected light beam is different, and the reflected light beam has a different light path difference, which decoherent light beams, reduces the speckle, interference fringes, and diffraction fringes caused by the coherence of incident light of the optical system, and improves the imaging resolution of the optical system.
Through the design of the mirror array, the coherent beam can be effectively removed, speckle, interference fringes and diffraction fringes can be reduced, and the imaging resolution of the optical system can be improved.
