[0003] In recent years, the application fields of electro-mechanical optical systems with adjustable ability have been continuously expanded and extended, and the defects of the method of functionalized light wave conversion by coupling conventional light converging and light diverging lenses have become increasingly prominent, mainly reflected in The following aspects: (1) Because the optical lens with a fixed shape and profile presents non-adjustable beam transformation capabilities, only by adjusting the lens spacing to construct a specific beam shape and light energy transport form and perform modulation operations; (2) through The change of lens configuration by mechanical movement needs to be carried out in a specific order, the response is slow, time-consuming, and the inertia is large, and it needs to be matched with complex driving and control devices. Due to the intrinsic continuity of movement, it is impossible to perform arbitrary optical state cut-in or jump; (3) It is difficult Flexible access to the optical path or coupling with other optical optoelectronic mechanical devices; (4) It is impossible to perform functional beam conversion for photosensitive arrays such as CCD, CMOS or FPAs based on modern microelectronics and optoelectronics processes, and perform control of wavefront, wave spectrum, and wave Construction of optical-optical integrated imaging detection architecture based on vector, polarization, and energy flow, as well as chip-based transformation
