Unique methods and apparatus are provided for rapidly identifying microscopic particles, such as protozoa and other microbes suspended in a fluid or gas. In one, embodied form, the method comprises illuminating the particles to be detected with an, intense light source such as a laser detecting scattered light by means of an array of, optical sensors surrounding a detection zone converting the detected light to , an, electrical signal and comparing the derived signal with at least one frequency-of-, occurrence/probability histogram curve to qualitatively and/or quantitatively identify, the microscopic particles present.
