Abstract (en)
[origin: WO0136937A1] Providing information relating to two or more illuminated particles, bubbles, and/or droplets where the light providers are positioned so, relatively to the two or more particles, bubbles, and/or droplets and the detecting means, that at least two waves are reflected or refracted by the two or more particles, bubbles, and/or droplets toward the detector, the waves all having been either reflected by the two or more particles, bubbles, and/or droplets or all having been refracted a predetermined number of times within the two or more particles, bubbles, and/or droplets, the information being derived from spatial information from interfering waves generated when the waves from each of the two or more particles, bubbles, and/or droplets interfere on different parts of a sensitive area of the area detector or the line detector. Also, when more than one interfering pattern is used, the light waves from the particles may be refracted to reflected any number of times.
