  • Patent number: 7259362
    Abstract: An electro-optic device is disclosed which has a plurality of independently-gatable portions. One example is an image intensifier having a number of segmented photocathode areas (GP). The corresponding portions of the intensifier can be energized independently via contact stripe (CS). Used in conjunction with an appropriate trigger signal generator, imaging device and beam splitter, the device may be used to capture a series of images at very high speed. An electrical device having a reflective tunnel for generating a plurality of input images is also disclosed.
    Type: Grant

  • Patent number: 6157409
    Abstract: A high speed imaging apparatus for high speed imaging in two dimensions is described. The apparatus comprises a plurality of image storing devices 1 to 8 arranged for receiving and storing images in two dimensions, exposure means for exposing respective ones of the devices to respective images of a sequence of images received by the apparatus, erasure means for erasing any previously stored image in the device to be exposed prior to exposure, read means for reading images stored in said devices, and stop means for stopping the exposure of said devices and the erasure of previously stored images when the apparatus receives a trigger signal representing occurrence of an event. This enables at least one image received by the apparatus before receipt of the trigger signal to be read from the apparatus after receipt thereof. The apparatus therefore provides for recordal, and subsequent retrieval of image information relating to an event received prior to detection of the event.
