Outline of Final Research Achievements |
This research aims at evaluating 3D display performance with the spatial cross modulation (SCM) method, that is our simple generation method of an arbitrary complex amplitude distribution, using new optical configuration. First, a high-speed digital encoder and a high-speed basic motion simulator for 3D display system were constructed by using General-purpose computing on graphics processing units (GPGPU). Next, 3D display performance of the SCM with newly proposed optical configuration was evaluated using the basic motion simulator. As a result, we have clarified the following: The new SCM has a 3D display capability as is the case with the conventional SCM. The same image quality as the conventional SCM can be obtained with the new SCM even if a diffuser with a coarse pixel pitch is used. A projected image about three times larger than that of the conventional SCM can be obtained with the new SCM.
