我们提出了一个非永久性的附加功能，使全光成像与标准相机。我们的设计是基于物理复制机制，该机制将传感器图像倍增成多个相同的副本，这些副本仍然携带感兴趣的全光信息。通过不同的光学滤波器，我们可以恢复所需的信息。对设计的微小修改还允许孔径子采样，并且因此允许光场成像。由于我们设计中的滤波器是可更换的，因此可以针对不同的成像目的进行重新配置。我们在一个原型设置，高动态范围，多光谱，偏振和光场成像，可以实现与我们的设计。
We propose a non-permanent add-on that enables plenoptic imaging with standard cameras. Our design is based on a physical copying mechanism that multiplies a sensor image into a number of identical copies that still carry the plenoptic information of interest. Via different optical filters, we can then recover the desired information. A minor modification of the design also allows for aperture sub-sampling and, hence, light-field imaging. As the filters in our design are exchangeable, a reconfiguration for different imaging purposes is possible. We show in a prototype setup that high dynamic range, multispectral, polarization, and light-field imaging can be achieved with our design.
