A streak camera is an instrument for measuring the variation in a pulse of light's intensity with time. They are used to measure the pulse duration of some ultrafast laser systems and for applications such as time-resolved spectroscopy and LIDAR. ==Operation== A streak camera operates by transforming the temporal profile of a light pulse into a spatial profile on a detector, by causing a time-varying deflection of the light across the width of the detector. In particular, a light pulse enters the instrument through a narrow slit along one direction. It then gets deflected in the perpendicular direction so that photons that arrive first hit the detector at a different position compared to photons that arrive later.〔 (【引用サイトリンク】 url = http://learn.hamamatsu.com/tutorials/java/streakcamera/ ) 〕 The resulting image forms a "streak" of light, from which the duration, and other temporal properties, of the light pulse can be inferred. Usually, in order to record periodic phenomena, a streak camera needs to be triggered accordingly, similarly to an oscilloscope. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「streak camera」の詳細全文を読む スポンサード リンク
