REAL-TIME CONSTRUCTION AND MODULATION SYSTEM AND METHOD FOR MICRO-NANO LIGHT FIELD

Disclosed are a real-time construction and modulation system and method for a micro-nano light field. The system comprises a light source, spatial filter units (8, 9), a 4F optical system and a light wave modulation unit (4), wherein the 4F optical system comprises a first lens (group) (1) and a second lens (group) (2) arranged in sequence along a light path. Real-time regulation and control of an incident wave surface are realized by means of a phase element or a phase element group (5); selection of an incident photon wave surface and a light wave modulation optical component pixel, and regulation and control of parameters, such as an effective pixel region and spatial filtering of an imaging plane light field, are realized by means of the spatial filter units (8, 9); and finally spatial filtering/spatial time-division filtering and/or a change in relative positions of phase elements are used to realize continuous modulation of a pattern, a pattern distribution region and structural parameters of the patter
