Abstract: The present invention relates to a system and method for determining material composition of a liquid solution. The technique includes providing acoustic excitation to the liquid solution and directing coherent illumination passing through the solution, collecting light passing through the solution by a camera unit for generating at least one image data indicative of speckle patterns. Utilizing data on variations of speckle patterns in response to excitation frequency determines material composition of the solution.

Abstract: A system and technique for monitoring of one or more parameters of a sample are presented. The system comprising: an illumination unit configured for providing coherent illumination of at least two wavelength ranges and for directing said coherent illumination onto an inspection region, and a collection unit configured for collecting light returning from the inspection region and generate one or more image data pieces associated with speckle pattern generated at an intermediate plane between said inspection region and said collection unit. The use of illumination having at least two different wavelength ranges provides generation of speckles associated with mutual- interference of light of the different wavelength ranges, enabling higher efficiency and stability with respect to movement of the inspection region.

Abstract: A method and system for use in detection of a periodic signal are described. The method comprising: providing data about periodicity of the periodic signal; sampling said periodic signal at a sampling rate along a plurality of periods of said signal, said sampling rate being selected as having temporal location of at least one sampling event along a corresponding period thereof varies for each period for a desired number of the periods; arranging sampled data pieces in accordance with sample time thereof with respect to time within a period of said periodic signal; and reconstructing a profile of said periodic signal from said plurality of periods being sampled at a desired resolution being greater than resolution associated with said sampling rate. The variation in temporal location of sampling event may be provided by proper selection of sampling rate, or by varying time of sampling rate in accordance with the period of the periodic signal.
