MODULATOR, DEVICE FOR OBTAINING OPTICAL FIELD DATA USING THE MODULATOR, AND DEVICE AND METHOD FOR PROCESSING OPTICAL FIELD DATA USING THE MODULATOR

摘要

PROBLEM TO BE SOLVED: To provide a modulator, a device for obtaining optical field data using the modulator, and a device and a method for processing optical field data using the modulator.

SOLUTION: Technologies for obtaining and processing optical field data on a plurality of images are disclosed. The device for obtaining optical data on one side includes: a modulator containing attenuation patterns for space-modulating a four-dimensional optical field of an image; and a sensor for obtaining a two-dimensional signal of the space-modulated four-dimensional optical field. More space data in a low angular frequency region than that in a high angular frequency region are obtained by the attenuation patterns of the modulator.
