Optical tomography for biomedical applications by digital interference holography

Learning approach to optical tomography

Optical tomography has been widely investigated for biomedical imaging applications. In recent years optical tomography has been combined with digital holography and has been employed to produce high-quality images of phase objects such as cells. In this paper we describe a method for imaging 3D phase objects in a tomographic configuration implemented by training an artificial neural network to...

Chapter 2 DIGITAL HOLOGRAPHY AND MULTI- WAVELENGTH INTERFERENCE TECHNIQUES

Recent developments in digital holography techniques are presented. The Fourier transform and convolution methods to calculate the diffraction fields are compared with the angular spectrum method, which allows short reconstruction distances down to zero with flexibility in the control of image noise. Examples of applications of digital holography in biological microscopy are presented with subm...

Optical tomography and digital holography

Wavelength-scanning digital interference holography for optical section imaging.

We propose and experimentally demonstrate a simple digital holographic method that allows reconstruction of three-dimensional object images with a narrow depth of focus or axial resolution. A number of holograms are optically generated by use of different wavelengths spaced at regular intervals. The holograms are recorded on a digital camera and reconstructed numerically. Multiwavelength interf...
