An approximation of the cosine function is one of the solution for reducing the computational load in holographic calculation. Our previous work, which approximates the cosine function by a combination of addition, modulo and absolute operation, is proved to be effective for accelerating holographic calculation; however, its approximation error also degrades a performance of a hologram. In this study, we propose an error compensation method which is based on our previous work, and succeeded in reducing the mean absolute error by about 85% compared to our previous work. Moreover, our work also succeeded in improving an image quality of reconstruction image of computer-generated hologram. |
