Abstract: An advance in ultra-high-resolution optical imaging has been achieved by the introduction of iterative high-resolution image-building algorithms to incoherent holography. A recorded FINCH hologram is used as the basis of a method in which a high resolution image is built using detailed knowledge of the point spread functions of the FINCH hologram or reconstructed image, and then iteratively improved by successive algorithm generations of comparison to the recorded FINCH hologram and alteration of the high resolution image.

Abstract: A system and method to produce a hologram of a single plane of a three dimensional object includes an electromagnetic radiation assembly to elicit electromagnetic radiation from a single plane of said object, and an assembly to direct the elicited electromagnetic radiation toward a hologram-forming assembly. The hologram-forming assembly creates a hologram that is recorded by an image capture assembly and then further processed to create maximum resolution images free of an inherent holographic artifact.

Abstract: A new optical arrangement that creates high efficiency, high quality Fresnel Incoherent Correlation Holography (FINCH) holograms using transmission liquid crystal GRIN (TLCGRIN) diffractive lenses has been invented. This is in contrast to the universal practice in the field of using a reflective spatial light modulator (SLM) to separate sample and reference beams. Polarization sensitive TLCGRIN lenses enable a straight optical path, have 95% transmission efficiency, are analog devices without pixels and are free of many limitations of reflective SLM devices. An additional advantage is that they create an incoherent holographic system that is achromatic over a wide bandwidth. Two spherical beams created by the combination of a glass and a polarization sensitive TLCGRIN lenses interfere and a hologram is recorded by a digital camera. FINCH configurations which increase signal to noise ratios and imaging speed are also described.

Abstract: The inventors have discovered a method to improve image quality in holography and, for the first time, utilize lenses made from birefringent materials to advantageously split an incoming beam of either coherent or incoherent light into two coincident beams with different focal lengths that interfere with one another and thus create holograms free of electro-optical or pixelated devices. This discovery has many advantages over current methods to create holograms in which many components, including multiple lenses, other electro-optical devices, and/or beam paths are necessary to create holograms. The current invention provides a purely optical holographic process which has better performance and holographic simplicity, in addition to being able to miniaturize holographic processes more than is currently possible in state of the art holography systems.

Abstract: Techniques to improve image quality in holography utilizing lenses made from materials with non-quantized anisotropic electromagnetic properties, such as birefringent materials, to advantageously split an incoming beam of light into two coincident beams with different focal lengths that interfere with one another and thus create holograms free of electro-optical or pixelated devices are disclosed for microscopy and other applications. The use of thin birefringent lenses and single crystal alpha-BBO lenses are introduced. Corresponding systems, methods and apparatuses are described.

Abstract: An apparatus for producing a hologram includes a collimation lens configured to receive incoherent light emitted from an object; a spatial light modulator (SLM) that includes at least one diffractive lens which is configured to receive the incoherent light from the collimation lens and split the incoherent light into two beams that interfere with each other; and a camera configured to record the interference pattern of the two beams to create a hologram, wherein a ratio between a distance from the SLM to the camera and a focal length of the diffractive lens is greater than 1.
