VISAR ORVIS Apparatus for measuring speeding of moving object using VISAR or ORVIS

摘要

The present invention relates to an apparatus for measuring the velocity of a moving object using VISAR or ORVIS. In the apparatus for measuring the velocity of a moving object by detecting a fringe movement amount due to inference light of an object to be measured by including an inference system of the VISAR or ORVIS, a first optical unit (110) which is arranged to be adjacent to the object (1) to be measured and concentrates measurement light and a first optical fiber bundle (120) for optical transmission between the first optical unit and an input terminal of the interference optical system are included. Accordingly, the present invention can improve a signal-to-noise ratio.
