Unique methods and apparatus are provided for rapidly identifying microscop ic 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 detecte d 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 quantitativel y identify the microscopic particles present.
