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.
