چکیده

Digital holography has some desirable properties for refractometry of microscopic objects since it gives phase and amplitude information of an object in all depths of focus from one set of exposures. The refractive index of the object can be determined by observation of the movements of the Becke lines between different focus depths. It is also shown that one single phase image provides an independent technique to determine sign of the relief between an object and the surrounding medium.

Theoretical analysis of three-dimensional imaging and recognition of micro-organisms with a single-exposure on-line holographic microscope.

Single-exposure on-line (SEOL) digital holography is a recently proposed technique for monitoring, visualization, and recognition of three-dimensional (3D) objects. In contrast to traditional multi-exposure on-line digital holography, it uses only one exposure, which makes it particularly suitable for imaging and recognizing moving micro-organisms. However, the cost of using only one exposure i...

Real-time 3d Shape Measurement of Micro Droplet Using Digital Holographic Microscopy

This paper reports the development of a microscopic 3D shape measuring method based on digital holographic microscopy, and its application to a microscopic droplet which changes in shape as time progresses. The use of an off-axis holographic/interferometric optical system enables measuring the geometry of microscopic objects in 3D and in real time. The measurement is performed in the volume of ...

حذف پراش مرتبه صفر در تصاویر بازسازی شده به روش تمام‌نگاری دیجیتالی

The numerically reconstructed images in digital holography contain two undesirable features. After reconstruction, the zero order diffraction as well as the complex conjugate image will be present in pictures and drastically reduce their qualities. Practical applications of digital holography in the context of characterization and measuring the physical properties of objects require the suppres...

Digital holographic microscopy with dual-wavelength phase unwrapping.

We apply the techniques of digital holography to obtain microscopic three-dimensional images of biological cells. The optical system is capable of microscopic holography with diffraction-limited resolution by projecting a magnified image of a microscopic hologram plane onto a CCD plane. Two-wavelength phase-imaging digital holography is applied to produce unwrapped phase images of biological ce...

Pc-based Digital Holographic Microscope with Image Reconstruction Improvement Software

Microscope has been widely used to observe microscopic objects. The types of microscope are varied according to its function. The conventional optical microscope only provides intensity information of an object and it has some difficulties to provide information about the real shape of the object and the projection of the object in different depth and perspective. In addition, optical microscop...
