你肯定是拼命找寻着捷径，靠某种超理智的程序，以光的速度摸索着真理的。
This does not involve holographic images of the usual sort, but is a way of projecting beams of light wherever they are needed.
它不是常见的投影图像，而是一种新的投射光线到所需位置的方法。
He has claimed that by slowing down light by way of an optical illusion, the light can then be bent around an object to 'conceal' it.
他称，通过一种光幻觉可以使光线变得迟缓，从而光线可以弯绕着物体而达到“隐形”效果。
