Abstract
一个四维(4D:3D+时间)多平面宽带成像***可以实时记录3D多平面多色像。该成像***包括：一个或多个可生成各个衍射级对应的焦距和空间位置的非再入型二次扭曲(non‑reentry quadratically distorted：NRQD)光栅(5)，从而实现在多个物/像平面(2)和同一个像/物平面(7)之间实时传送波前信息；通过将入射光分散成一束按照光谱成分横向排列的平行光，限制色差引起的图像横向弥散的棱栅***(4)；用于调整光路的透镜***(3)，以及光检测器件(6)。在该光学***中，多个物/像平面(2)、透镜***(3)、棱栅***(4)、NRQD光栅(5)、光检测器件(6)、以及单个像/物平面(7)都位于同一个光轴(1)。这个简单、易用且集成化高的光学***可以满足多种不同的需要，有广阔的应用前景。
