Homodyne scanning holography.
We have developed a modified version of a scanning holography microscope in which the Fresnel Zone Plates (FZP) are created by a homodyne rather than a heterodyne interferometer. Therefore, during the scanning the projected pattern on the specimen is frozen rather than varied as previously. In each scanning period the system produces an on-axis Fresnel hologram. The twin image problem is solved...
متن کاملVariable tomographic scanning with wavelength scanning digital interference holography
We present a new method for variable tomographic scanning based on the wavelength scanning digital interference holography (WSDIH). A series of holograms are generated with a range of scanned wavelengths. The object field is reconstructed in a number of selected tilted planes from each hologram, and the numerical superposition of all the tilted object fields results in a variable tomographic sc...
متن کاملLightfront Formalism versus Holography&Chiral Scanning∗
The limitations of the approach based on using fields restricted to the lightfront (Lightfront Quantization or p→ ∞ Frame Approach) which drive quantum fields towards canonical and ultimately free fields are well known. Here we propose a new concept which does not suffer from this limitation. It is based on a procedure which cannot be directly formulated in terms of pointlike fields but require...
متن کاملOn the fundamentals of optical scanning holography
Optical scanning holography is a real-time holographic recording technique in which holographic information about a three-dimensional 3D object is acquired using a single two-dimensional active optical scan. Applications of the technique include optical scanning microscopy, pattern recognition, 3D holographic display, and optical remote sensing. This paper introduces the basics of optical scann...
متن کاملOptical Scanning Holography - Proceedings of the IEEE
This paper provides a tutorial on the principles of holography, followed by a review of a newly developed 3-0 imaging technique in which 3-0 optical information of an object can be extracted by a 2 -0 optical scan of the object. The technique is called optical scanning holography (OSH). In the context of optical scanning holography, we discuss some of its potential applications such as holograp...
