Abstract: The invention utilizes a digital holographic adaptive optics (DHAO) system to replace hardware components in a conventional AO system with numerical processing for wavefront measurement and compensation of aberration by the principles of digital holography. Wavefront sensing and correction by DHAO have almost the full resolution of a CCD camera. The approach is inherently faster than conventional AO because it does not involve feedback and iteration, and the dynamic range of deformation measurement is essentially unlimited. The new aberration correction system can be incorporated into a conventional fundus camera with minor modification and achieve high resolution imaging of a retinal cone mosaic. It can generate profiles of the retinal vasculature and measure blood flow. It can also provide real-time profiles of ocular aberration during refractive (Lasik) surgery and generate three-dimensional maps of intraocular debris.

Abstract: A series of holograms is recorded by synchronizing a camera with laser pulses under the control of a digital delay generator. Amplitude and phase images are calculated while image distances are adjusted for the best focus on the object under observation. The amplitude and phase images are reconstructed while adjusting the image distances over a predetermined range to maintain the object in focus. Numerical superposition of a plurality of holographic fields taken with varying wavelengths provides high resolution microscopic three-dimensional imaging. Numerical reconstruction is based on an angular spectrum method that enables calculation of the image at any distance from the hologram plane. Wavelength scanning digital interference holography also enables image reconstruction along an arbitrarily tilted plane.

Abstract: Two-dimensional and three-dimensional optical coherence tomography is obtained by differential imaging of full-frame interference images using a white light source. Full-color tomographic imaging is also possible by processing the three-color channels of the interference images. A technique is described to obtain two-dimensional OCT images with full natural color representation. In a particular embodiment, the interference image is acquired using a color camera and the three-color channels are processed separately, recomposing the final image. In an additional embodiment, the interference images are acquired using separate red, blue and green light sources and the three color channels are combined to recompose the final image.

Abstract: A simple digital holographic apparatus and method allow reconstruction of three-dimensional objects with a very narrow depth of focus or high axial resolution. A number of holograms are optically generated using different wavelengths spaced at regular intervals. They are recorded, such as on a digital camera, and are reconstructed numerically. Multiwavelength interference of the holograms results in contour planes of very small thickness and wide separation. Objects at different distances from the hologram plane are imaged clearly and independently with complete suppression of the out-of-focus images. The technique is uniquely available only in digital holography and has applications in holographic microscopy.

Abstract: The present invention is a phase-imaging technique by digital holography that eliminates the problem of 2&pgr;-ambiguity. The technique is based on a combination of two or more digital holograms generated using multiple wavelengths. For a two-wavelength experiment, the phase maps of two digital holograms of different wavelengths are subtracted which yields another phase map whose effective wavelength is inversely proportional to the difference of wavelengths. Using two holograms made with a 633 nm HeNe laser and a 532 nm doubled YAG laser an image was obtained that is a 3D reconstruction of a reflective surface with axial resolution of ˜10 nm over a range of −5 um, without any phase discontinuity over this range. The method can be extended to three wavelengths or more in order to reduce the effect of phase noise further.

Abstract: An adjustable nunchaku (10) comprises a pair of handles (12,14) attached together with a flexible member (20). The flexible member (20) is selectively attached to the handles (12,14) so that the length of flexible member (20) separating the handles (12,14) can be easily adjusted. The excess length of flexibly member (20) not used to hold the handles (12,14) together is stored in a passageway (26) in the handles (12,14). Further, the handles (12,14) are selectively attached to the flexible member (20) so that the handles (12,14) can be interchanged to change or fix the handles (12,14).
