ACTIVE VARIABLE SPECKLE ILLUMINATION WIDE-FIELD HIGH-RESOLUTION IMAGING APPATATUS AND IMAGING METHOD USING THE SAME

摘要

An imaging device according to an embodiment of the present invention includes a light source configured to irradiate coherent light having a single wavelength, an active light modulator configured to change any one of a wavefront and a polarization state of light irradiated from the light source, and an active A diffuser having an irregular structure surface that forms a speckle pattern by scattering the light modulated by the light modulator, an optical system including the speckle pattern and filtering the light passing through the sample as an object, and the light passing through the optical system An image sensor for acquiring a generated image, and a processor for obtaining a high-resolution image by repeatedly superimposing a plurality of low-resolution images acquired from the image sensor in a Fourier domain, wherein each of the plurality of low-resolution images uses an active light modulator to emit different light It can be obtained by modulating
