This article discusses optical methods and technologies that can register, transform, store, transmit, and reproduce large arrays of information. Digital holograms recorded using photographic equipment of various types is common carriers of experimentally recorded information. The size of digital hologram files is several tens of megabytes. Hence, for the storage and transmission of holographic data archives via communication channels, holograms should be compressed. Binarization represents one of the options for reducing the hologram size. For binarization, an iterative adaptive method for selecting the weight coefficients of the error diffusion procedure is proposed. The method has been tested on digital holograms that were optically recorded under various conditions. The quality of the measured objects was evaluated through numerical methods of image reconstruction and after displaying digital holograms on a micromirror light modulator. The proposed method can be used for compressing and storing holographic data, measuring the characteristics and shape of micro- and macroobjects, and fast optical image reconstruction using a micromirror light modulator. © 2022, Springer Science+Business Media, LLC, part of Springer Nature.

Shot Noise and Fixed-Pattern Noise Effects on Digital Hologram Reconstruction

© 2020Digital holography allows registering and reconstructing information about 3D objects and 3D scenes. There are several limitations related to reconstructed image quality: speckle noise, twin images, zero order, light (shot noise) and dark temporal noise, camera fixed-pattern noise (spatial noise), dynamic range, and quantization noise. These restrictions determine the maximum possible signal-to-noise ratio (SNR) of digital holograms and reconstructed images. This work is concerned with studying the effect of a digital camera's main noise components on hologram reconstruction. Analytical equations for estimation of SNR of reconstructed amplitude image were obtained. They relate to a number of values: shot noise, dark temporal noise, fixed-pattern noise, camera's dynamic range, quantization noise, reference and object beam intensities, and the ratio between the object area and the entire reconstructed field. The resulting equation was tested experimentally using digital holograms of diffusely scattering objects. Characteristics of different types of CCD and CMOS cameras were used: digital single-lens reflex (DSLR), scientific, industrial, and video surveillance cameras. The effect of the camera noise on the phase image reconstruction was also estimated. The resulting equations make it possible to estimate the camera noise's effect on the reconstructed images before the experiments were conducted. As a result, the illumination value, exposure time, object size, and other experimental conditions can be pre-selected to reduce the noise in holograms used in metrological and infrared applications and optical encryption.

Downloading of the abstract is permitted for personal use only.Digital holography is technique for registering of 2D- and 3D-scenes characteristics: amplitude or phase images of object, roughness, and etc. Numerical reconstruction allows fast images recovery. However high quality optical reconstruction is not so fast due to the hologram transferring to the spatial light modulator (SLM), hologram digital preprocessing, SLM calibration, and etc. In this work we analyzed possibilities of fast processing of the holograms for increasing of quality of optically reconstructed images. Amplitude type holograms were registered and images were optically reconstructed using phase liquid crystal SLM. Various techniques of improvement of reconstruction quality were used.
