The method of " sky+time-measuring gauge " measures the speed that bullet leaps specified point, will two performance phases
As sky be placed on trajectory line, measuring bullet using time-measuring gauge leaps time of two skies,
According to the distance between two skies, you can try to achieve flying speed of the bullet between sky.Cause
This, the performance of sky is good and bad and uniformity each other determines the measuring accuracy of velocity of shot.
At the time of sky leaps search coverage by electrooptical device to catch bullet, due to bullet at a high speed
Flight and special bullet shape, therefore instrument manufacturing engineer is difficult to use instrument and equipment in laboratory
To detect that different bullets and different flying speeds cause the exporting change of sky, that is, it is difficult
Demarcate the measuring accuracy of sky.At present, can only be by the sky of new production and by using at one section
Between after need the sky examined and determine again to transport to target range, from rifle known to the velocity of shot scope of part
Tool carries out ball firing, and the velocity of shot that time-measuring gauge is surveyed is compared to determine with known velocity of shot scope
Property evaluate the measuring accuracy of sky, therefore calibration method is owed that science, verification process be cumbersome, calibrating knot
Really not comprehensive enough, calibrating somewhat expensive, has had a strong impact on the normal of sky and has used.

With computer.Turn on the power, computer calculates with bullet speed according to the bullet kind of setting and produces specific numeral
Signal, generation analog waveform is shown over the display, and is sent to signal generator；Signal generator
Corresponding analog electrical signal is produced according to the data signal of reception, two array of source are sent respectively to；
Array of source sends the light of light intensity gradual change, and is irradiated to the optical-electrical converter positioned at sky light-receiving window
Part, the output of electrooptical device exports electric signal after processing；It is defeated that time-measuring gauge measures two skies
The time interval of the electric signal gone out, and it is sent to computer.Computer goes out according to sky distance computation
Bullet speed, surveys bullet speed by sky and is compared with the bullet speed of computer settings, you can obtain the survey of sky
Precision is tried, dynamic calibration and the calibrating function of sky is realized.
