| Research Abstract |
In order to develop a real-time three-dimensional measurement system for moving object with high accuracy which it is difficult for conventional techniques to realize, the author aimed to accelerate the calculation processes of parallel digital holography which is a core technique in this work. By numerical simulations, the author confirmed that GPU and FPGA was capable of carrying out the calculation process for realizing high-accuracy measurement up to 11.4 times and 6.9 times faster than that by CPU, respectively. In addition, the author succeeded in obtaining displacement of diaphragm of a loudspeaker vibrating at 1 kHz by experimental demonstration.
