ABSTRACT:
A dynamic particulate observation apparatus for monitoring a moving particle comprises a black box having an internal space enclosed therewithin, which shields said space from the infiltration of light outside; means for generating particles moving across said black box; means for emitting flash light within said black box at a predetermined frequency; and means for taking down the images of the particles generated by said generating means when said emitting means emits flashlights. The dynamic particulate observation apparatus according to this invention is cheap and easy to assemble, and renders all the necessary functions of a conventional dynamic particulate observation apparatus.
