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.

A hologram image acquiring apparatus includes a linear polarizer that filters incident light reflected by an object into a polarized component of a specific angle; a spherical lens that partially converts light that is incident through the linear polarizer to a spherical waveform; and a phase shifter that converts a part of the light incident through the spherical lens to a plane waveform having a respective phase per pixel unit.

A partial-aperture imaging system, including one or more partial-aperture units, each including) one or more partial apertures disposed over a periphery of a circular area representing a full aperture having, each partial aperture being directed towards scenery, while the total area of the partial apertures spans only a portion of the area of the full aperture; one CPM for each of the partial apertures, the CPM receiving, one at a time, from a respective partial aperture at least one point-object image and at least one complex-object image, the CPM modulating by a same random code the phases of pixels of one or more pairs of the point-object and complex-object images, to form PORIs and CORIs; an imager for optically receiving the PORIeach PORI being defined as a PSF, respectively, and at least one CORI, and for storing; and a processor to form a final image.

The invention relates to a free-beam interferometric method for illuminating a sequence of sectional areas in the interior of the light-scattering object. The method makes it possible for the user to select a larger image field and/or a higher image resolution than previously possible with the occurrence of self-interference of the specimen light from a scattering specimen.

A light source device connected to an optical fiber and emit light from the optical fiber, the device includes: a plurality of laser light sources to respectively emit light at different wavelengths; a current source to supply a drive current with a superimposed alternating-current component to each laser light source; a light source control section to selectively switch the laser light sources by controlling the current sources; a plurality of optical systems disposed in optical paths of the respective laser light sources to reflect the light from the respective laser light sources to an incident end of the optical fiber and to reflect return light reflected on the incident end to the respective laser light sources; and a return light adjustment section to adjust an amount of the return light to continuously spread a spectrum of the light emitted from the optical fiber.

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.

The invention relates to an interferometric method, in which the light scattered by an object is imaged onto an electronic camera, wherein a sample light component is assigned to scattering sites on a sectional face in the interior of the object. This sample light component can be separated from the contributions of the other sample light components by processing of the camera image and leads to a sectional image. A particular advantage of the invention lies in the fact that multiple parallel sectional faces can be exposed sequentially at predetermined intervals from each other in the interior of the object. Such a sequence of sectional images can be used to calculate a solid model of the object.
