这种轻触型工具播放的近距离图像是在0.4英寸的微小型显示器上反射的激光形成的，使用全息摄影术以保持图画尽管在投影尖角上依然聚焦。
The Light Touch casts a big image from up close by bouncing lasers off a 0.4-inch microdisplay, using techniques from holography to keep the picture in focus despite the sharp projection angle.
由于色散的增加，等分角效应对于投影系统比对于直视型显示器更为合适。
Owing to the increased color dispersion, this bisector effect is more suitable for projection systems than for direct-view displays.
