| description | To provide a droplet imaging device that can prevent mist scattering upon photographing a droplet of a photograph object in flight from adhering on illumination or an optical component such as a lens, without affecting a flight direction of the droplet or a speed thereof.SOLUTION: A droplet imaging device 1, which photographs a droplet Q in flight ejected from a droplet ejection nozzle N, comprises: an illumination unit 2 that irradiates, with illumination light, a photographing area set in a route where the droplet ejected from the droplet ejection nozzle N flies; a photographing camera 3 that photographs the photograph area; and a lens part 4 that causes a lateral cross section shape of the droplet passing through the photograph area to be image-formed on an image pick-up element of the photographing camera, in which on a photograph area side of at least one of a light emission part of the illumination unit and the lens part, the droplet imaging device is provided with a mist electrification collection unit 5 that electrifies and collects pollution cause mist Md being adhered on the light emission part and/or an optical component of the lens unit and causing pollution, of scattering mist caused by the ejection of the droplet.SELECTED DRAWING: Figure 1
【課題】撮像対象とする液滴の飛翔方向や速度に影響を与えることなく、当該飛翔中の液滴を撮像する際に飛散したミストが照明やレンズ等の光学部品に付着するのを防ぐことができる、液滴撮像装置を提供する。【解決手段】液滴吐出ノズルから吐出された飛翔中の液滴Ｑを撮像する液滴撮像装置１であって、液滴吐出ノズルＮから吐出された液滴が飛翔する経路に設定された撮像領域に向けて照明光を照射する照明部２と、撮像領域を撮像する撮像カメラ３と、撮像領域を通過する液滴の横断面形状を、撮像カメラの撮像素子に結像させるレンズ部４を備え、照明部の発光部及びレンズ部の少なくとも一方の撮像領域側には、液滴の吐出に起因して飛散したミストのうち、当該発光部及び／又は当該レンズ部の光学部品に付着して汚濁の原因となる汚濁原因ミストＭｄを帯電させて捕集するミスト帯電捕集部５を備えた。【選択図】図１ |
