Title: Use of a focusing vortex lens as the objective in spiral phase contrast microscopy

Abstract

A method and objective apparatus are provided for implementing an enhanced phase contrast microscope. A focusing vortex lens, defined by a diffractive spiral zone plate (SZP) lens, is used for the objective for the phase contrast microscope. The SZP lens focuses and imparts a helical phase to incident illumination to image the specimen with spiral phase contrast. The spiral phase contrast microscope is sensitive to phase gradients in all sample axes. Replacing the objective of a microscope with the diffractive SZP lens of the invention immediately provides existing instruments with spiral phase contrast capability.

Contrast enhancing solution for use in confocal microscopy

Patent Tannous, Zeina; Torres, Abel; Gonzalez, Salvador

A method of optically detecting a tumor during surgery. The method includes imaging at least one test point defined on the tumor using a first optical imaging system to provide a first tumor image. The method further includes excising a first predetermined layer of the tumor for forming an in-vivo defect area. A predetermined contrast enhancing solution is disposed on the in-vivo defect area, which is adapted to interact with at least one cell anomaly, such as basal cell carcinoma, located on the in-vivo defect area for optically enhancing the cell anomaly. Thereafter the defect area can be optically imagedmore » « less

An image focusing means by using an opaque object to diffract x-rays

Patent Sommargren, Gary E [Santa Cruz, CA]; Weaver, H Joseph [Livermore, CA]

The invention provides a method and apparatus for focusing and imaging x-rays. An opaque sphere is used as a diffractive imaging element to diffract x-rays from an object so that the divergent x-ray wavefronts are transformed into convergent wavefronts and are brought to focus to form an image of the object with a large depth of field.

A radiograph system with an anode plate, a cathode plate, and a power source coupled to said anode plate and the cathode plate. At least two wires coupled between the anode plate and the cathode plate provide a configuration to form an X-pinch having a photon source size of less than five microns at energies above 2.5 keV. Material at the configuration forming the X-pinch vaporizes upon application of a suitable current to the wires forming a dense hot plasma and emitting a single x-ray pulse with sufficient photons having energies in the range of from about 2.5 keV tomore » « less

Method of making and structure of multilayer laue lens for focusing hard x-rays

Patent Liu, Chian Q.; Conley, Raymond P.; Macrander, Albert T.; ...

A zone plate multilayer structure includes a substrate carrying a plurality of alternating layers respectively formed of tungsten silicide (WSi2) and silicon (Si). The alternating layers are sequentially deposited precisely controlling a thickness of each layer from a minimum thickness of a first deposited layer adjacent the substrate to a maximum thickness of a last deposited layer. The first minimum thickness layer has a selected thickness of less than or equal to 5 nm with the thickness of the alternating layers monotonically increasing to provide a zone plate multilayer structure having a thickness of greater than 12 μm (microns).
