Super-resolution in incoherent optical imaging using synthetic aperture with Fresnel elements.

چکیده
We present a new lensless incoherent holographic system operating in a synthetic aperture mode. Spatial resolution exceeding the Rayleigh limit of the system is obtained by tiling digitally several Fresnel holographic elements into a complete Fresnel hologram of the observed object. Each element is acquired by the limited-aperture system from different point of view. This method is demonstrated experimentally by combining three holographic elements recorded with white light illumination which is emitted from a binary grating.

Synthetic Aperture Digital Holography
Synthetic aperture is a well-known super-resolution technique which extends the resolution capabilities of an imaging system beyond the theoretical Rayleigh limit dictated by the system's actual aperture. Using this technique, several patterns acquired by an aperture-limited system, from various locations, are tiled together to one large pattern which could be captured only by a virtual system ...
متن کاملEnhanced-resolution using modified configuration of Fresnel incoherent holographic recorder with synthetic aperture.
Synthetic aperture methods are commonly-used techniques for providing images with super-resolution qualities. We propose an improved design of the system, coined "synthetic aperture with Fresnel elements". The super-resolution capabilities of the proposed scheme are analyzed and experimentally demonstrated.
متن کاملEnhanced super resolution using Fresnel incoherent correlation holography with structured illumination.
The structured illumination (SI) technique has already been well established as a resolution enhancer in many studies and well demonstrated in many optical imaging systems during the past decade. The ability to use the SI in incoherent imaging systems was also introduced, especially in fluorescence microscopy. In this Letter, we propose and demonstrate a new approach to combine the SI technique...
متن کاملOptical sectioning using a digital Fresnel incoherent-holography-based confocal imaging system.
We propose a new type of confocal microscope using Fresnel incoherent correlation holography (FINCH). Presented here is a confocal configuration of FINCH using a phase pinhole and point illumination that is able to suppress out-of-focus information from the recorded hologram and hence combine the super-resolution capabilities of FINCH with the sectioning capabilities of confocal microscopy.
متن کاملCould SAFE concept be applied for designing a new synthetic aperture telescope?
Synthetic aperture with Fresnel elements (SAFE) is an incoherent holographic imaging system in which the complete hologram is a mosaic of several holograms captured from different points of view. In this paper we investigate a new scheme of SAFE which may be used as a basis for designing a new type of synthetic aperture telescopes. Laboratory in-door experiments may provide the proof of concept...
