我们实验演示了一种类似于1 mm厚的近红外相机，它由一个多能级的衍射透镜和一个传统的单色图像传感器组成。我们仔细测量了点扩展函数、调制传递函数、聚焦效率、像差和相机的视场。(C)2019年美国光学学会
We experimentally demonstrate a similar to 1-mm-thick near infrared camera comprised of a multi-level diffractive lens coupled with a conventional monochrome image sensor. We performed careful measurements of the point-spread function, the modulation transfer function, focusing efficiency, aberrations, and the field of view of the camera.
