The Development of a Digital Multichannel Correlator System for Light Scattering Experiments
نویسندگان
چکیده
The measurement of light scattering is a well established scientific method for the analysis of particle sizes in macromolecular solutions [1]. The spectrum of applications reaches from physics, over pharmacology, molecular and cell biology, immunology right up to environmental research. The underlying principle of this approach is the extraction of spectral information from light scattering using correlation techniques. The system at present, in the phase of design, represents a novel FPGA based real-time multi correlator system for multi angle dynamic and static light scattering experiments.

Abstract* Introduction: Visual system have been considered as among important sensory system in animals’ life span and their survival is closely related to normal visual system functioning. Since in previous studies it have been revealed that morphine consumption during pregnancy could lead to defect and delay in nervous system development in the embryos, in the present study, changes induc...
متن کاملPractical implementation of a high-speed multichannel correlator with fiber-optic delays.
We discuss architecture, subsystems, and applications of a multichannel digital correlator we constructed by using a combination of optical and electrical delays. Our system is capable of a 1-ns bin width in normal operation, when a derandomizer is used at the input stage and a 0.25-ns bin width when the derandomizer is bypassed. When switchable delay lines are used, the 16 real-time channels c...

Objectives: In this article, a new procedure for increasing the light penetration depth in a tissue is studied and simulated. It has been reported that the most important problem in biomedical optical imaging relates to the light penetration depth, and so this makes a dramatic restriction on its applications. In the optical imaging method, the detection of the backscattered pho...
متن کاملSingle-channel polychromatic pattern recognition by the use of a joint-transform correlator.
We present a single-channel system for color image recognition that is based on a joint-transform correlator setup. The color images are encoded as phase and amplitude functions, inspired from the Munsell color representation. A real-time implementation of the new codification method can be achieved by the use of a spatial light modulator operating in phase-only modulation mode. We determine th...
