WebOct 15, 2010 · Abstract. We report a dual plane in-line digital holographic microscopy technique that exploits the method of subtraction of average intensity of the entire hologram to suppress the zero-order diffracted wave. Two interferograms are recorded at different planes to eliminate the conjugate image. The experimental results demonstrate … WebDigital in-line soft X-ray holography (DIXH) is a lenseless approach towards microscopy at short wavelength. We present measurements which successfully prove that the original Gabor geometry can be applied to X-rays and a lateral resolution of 400 nm can be achieve
WebMay 1, 2006 · Digital in-line holographic microscopy is a promising new tool for high resolution imaging. We demonstrate, by using latex beads, that a considerable increase in numerical aperture, and, therefore, resolution can be achieved if the space between a source and a CCD camera chip is filled with a high refractive index medium. The high … WebThis report introduces a simple experimental method to accurately determine the location and geometry of objects in three dimensions, using digital inline holographic microscopy (DIHM). Broadly speaking, the accessible sample volume is defined by the camera …
