FIELD: analyzing or investigating materials. ^ SUBSTANCE: device comprises mirror-lens that focuses the light beam from the source within the space through which the aerosol particles flow. The re-emitting light fluxes are collected with an optical recording system and are directed to the field-effect diaphragm and, then, to photodetectors. The signals are then sent to the processing system. ^ EFFECT: enhanced sensitivity. ^ 4 dwg |
