Compact in-line lensfree digital holographic microscope
Phase imaging provides intensity contrast to visualize transparent samples such as found in biology without any staining. Among them, digital holographic microscopy (DHM) is a well-known quantitative phase method. Lensfree implementations of DHMs offer the added advantage to provide large field of views (several mm2 compared to several hundred μm2) and more compact setups that traditional DHM w...
متن کاملRobust, compact implementation of an off-axis digital holographic microscope.
Recent advances in digital technologies, such as high-speed computers and large-format digital imagers, have led to a burgeoning interest in the science and engineering of digital holographic microscopy (DHM). Here we report on a novel off-axis DHM, based on a twin-beam optical design, which avoids the limitations of prior systems, and provides many advantages, including compactness, intrinsic ...
متن کاملThree-Dimensional Identification of Microorganisms Using a Digital Holographic Microscope
This paper reports a method for three-dimensional (3D) analysis of shift-invariant pattern recognition and applies to holographic images digitally reconstructed from holographic microscopes. It is shown that the sequential application of a 2D filter to the plane-by-plane reconstruction of an optical field is exactly equivalent to the application of a more general filter with a 3D impulse respon...
متن کاملA Field-Portable Cell Analyzer without a Microscope and Reagents
This paper demonstrates a commercial-level field-portable lens-free cell analyzer called the NaviCell (No-stain and Automated Versatile Innovative cell analyzer) capable of automatically analyzing cell count and viability without employing an optical microscope and reagents. Based on the lens-free shadow imaging technique, the NaviCell (162 × 135 × 138 mm³ and 1.02 kg) has the advantage of prov...
متن کاملMems Measurement by Digital Holographic Microscope
A universal digital holographic microscope to measure shape and displacement of microelement and MEMS (MicroElectroMechnacalSystems) is presented. This device is designed to exploit a measurement for MEMS with either a smooth or a rough surface. The method is based on digital laser interferometry and digital laser speckle interferometry (TV holography) incorporated with optoelectronic devices i...
