BACKGROUND OF THE INVENTION The present invention relates to a device for accurately determining the beginning of a non-disposable one-shot event and an unprepared high-speed rotating mirror camera.

Existing high speed, unprepared, rotating mirror cameras allow you to record the physical plot being tracked, or part of it, to the final number of individual frames. The realization of an overall one-shot event whose duration is longer than that of the high-speed rotating mirror film recording film is very complicated and impossible when existing high-speed, unprepared rotary mirror cameras are used.

These drawbacks are eliminated by accurately determining the start of a non-disposable one-shot event by an unprepared high-speed rotating mirror camera according to the invention, the principle of which is that the input sensor recording the amount of physical action is connected to the timing input to which the sensor-sensitive output is coupled. light and located at a given distance from the first slot of the slit ring.

The device for accurately determining the start of a scanned one-shot event by an unprepared high speed camera with a rotating mirror allows accurate time orientation in the scanned one-shot physical event and generating an overall one-shot physical event from each time-shifted record. The exact time determination of the start of the scanned one-shot physical event by an unprepared high speed camera with a rotating mirror is realized by a pair of sensors, the location of which is shown in the attached figure. The input sensor 1, sensing the beginning of the physical event, actuates the time scale 3. The disposable physical event being viewed by the imaging system 4 and the rotating mirror 5 is scattered on the slot ring 6, at the beginning of which; A light-sensitive sensor 2 is located at a known distance from the first slot. The light-sensitive sensor 2 sends an output signal to the pulsed light beam, which stops the time scale 3. The time distance of the light-sensitive sensor 2 from the first slot 8 on the slot ring 6, and thus from the first figure 9 on the film strip 7, is given by the known angular velocity of the rotating mirror 5. The time span of the onset of the one-shot physical action from the first figure 9 on the film strip 7 is given by the invention by the sum of the time measured by the time scale 3 and the apparent time of transition of the light beam from the light sensitive sensor 2 to the first slot 8 on the slot ring 6.

Apparatus for accurately determining the start of a scanned single event by an unprepared high speed camera with a rotating mirror. it allows accurate time orientation in the scanned one-shot physical process and the creation of an overall one-shot physical event from individual time-shifted records.
