High speed events that are random in nature extreme in size or speed or have other challenging characteristics can be difficult or impossible to study using conventional high speed imaging techniques. New methods are required to capture images of such demanding applications. Recent technical advances applied to the design of electronic high speed imaging systems have resulted in entirely new tools and techniques for capturing images of fast and unpredictable events and expanding the conditions under which images can be made. The advances include a completely new high speed image recording technology and a special camera. The new recording device represents a revolution in the field of high speed imaging. The recorder stores digital images directly into solid state memory. The use of solid state memory offers a number of unique image capture modes very high picture quality and excellent performance under harsh environmental conditions. The special camera incorporates a dual stage image intensifier to overcome the traditional problems encountered with the lighting and exposure of high speed events. The cameras extreme light sensitivity allows images to be made under ambient illumination at high framing rates. The camera can also be gated to provide exposures as short as 10 microseconds resulting in blur free pictures like those generally obtained through the use of short duration strobes. The improvements in sensitivity and shuttering when compared to ordinary high speed video equipment results
