Apparatus and method for detecting bacteria with chaotic wave sensor in the bacterial culture dishes using

The Petri dishes bacteria detection device and method using a laser speckle. Microbial detection system, and on the basis of the incident light source, and the culture plate for irradiating light in the culture plate to detect microbial light measured with a laser speckle pattern (laser speckle) formed in the Petri dish at a predetermined interval, measurement a plurality of laser Spanish may include a measure for detecting whether the microorganisms are present in the Petri dish on the basis of the dynamic change of the class.
