Principle of Light Obscuration (HIAC)
A schematic representation of the light obscuration principle is shown in Fig. 3.8. A tungsten lamp produces a constant colli-mated beam of light that passes through a small rectangular passageway and impinges onto a photodiode. In a clear passageway, the light intensity received by the photodiode remains constant. Liquids can (low through the passageway between the light source and the photodiode. ***If a single particle transverses the light beam, there results a reduction in the normal amount of light received by the photodiode.*** This reduction of light and the measurable decrease in the output from the photodiode is proportional to the area of the particle interrupting the light flow. Thus, the light-obscuration principle measures particle size based on the diameter of a circle having an equivalent area. http://tinyurl.com/koq37j

Discussion
Но ответ ИМХО не точный. См. Reference. Здесь фактически по ослаблению света измеряется площадь тени частицы. Поэтому можно сказать, что это метод затенения. К затуханию и экстинкции это не имеет отношения.
