System and method to detection of particles in liquid or in air

Abstract

A method and system for detecting foreign particles in a liquid, the method and system include transmitting transmitted pulses of radiation, by a transmitter, towards a liquid conduit that is filled with liquid; wherein the transmitted pulses comprises pulses that differ from each by being associated with absorbance frequencies of different foreign particles; receiving, by a receiver, received pulses that propagated through liquid as a result of the transmission of the multiple transmitted pulses; comparing between the transmitted pulses and the received pulses to provide a comparison result; and determining a liquid contamination based on the comparison result.

We claim: 
     
         1 . A method for detecting foreign particles in a liquid, the method comprises: transmitting transmitted pulses of radiation, by a transmitter, towards a liquid conduit that is filled with liquid; wherein the transmitted pulses comprises pulses that differ from each by being associated with absorbance frequencies of different foreign particles;
 receiving, by a receiver, received pulses that propagated through liquid as a result of the transmission of multiple transmitted pulses;   comparing between the transmitted pulses and the received pulses to provide a comparison result; and   determining a liquid contamination based on the comparison result.
