Issues in Particle Field Characterization Using Digital Holography... [Pg.2074]

In digital holography, information capacity is mainly limited by two parameters (i) presence of speckle noise in the reconstruction images and (ii) size of CCD sensor. The influence of these two parameters on information capacity is discussed in the following subsections. [Pg.2074]

Fig. 1 Intensity variation along the depth (z) of reconstructed volume near the in-focus position (z ,i ) of a particle (diameter = dp) image reconstructed using lensiess digital holography and digital holographic microscopy...

Influence of CCD Sensor Size The limited number of pixels on CCD sensor also influences the information capacity of the digital holography... [Pg.2075]

Depth of Field The depth of measurement volume is decided by depth of field of digital holographic microscope. In digital holography, the depth of field is equal to the depth of the measurement volume unlike conventional microscopy in which depth of field is inversely proportional to the magnification of the objective lens. [Pg.2078]

The velocity field of fluid flow can be obtained by using either particle tracking velocimetry (PTV) or particle image velocimetry (PIV) approach. The PTV approach is most suitable when the particle concentration in the fluid is low. The PIV approach is used when the particle concentration is high. It is primarily based on the cross correlation between images acquired at two different time instances. Because digital holography... [Pg.2080]
