The present invention relates to a device and a method for measuring arrows paradox and velocity using a multiframe which increases accuracy by measuring the position of each frame when an arrow passes through a frame consisting of a photodiode and a laser by using the laser and the photodiode connected to a high-speed measuring device and applying linear interpolation between measured points. The present invention includes a movable multiframe where a rectangular frames consisting of a photodiode and an array facing the photodiode faces a launching pad; a laser module which is a light source inputted to the photodiode and a photodiode array module which is mounted on each frame to measure positions and outputs and changes a voltage level according to the intensity of light at an arbitrary point when the arrow passes through the center part of the movable multiframe; and a measuring device which measures the voltage level change of a photodiode array sensor which is generated when the arrow passes and outputs the voltage level change to a coordinate.
