Abstract

Researchers have proposed beam-splitting imaging methods to solve the problem that capturing the simultaneous view by multiple imaging instruments and positionally aligning them pixel by pixel. Beam-splitting prism and beam-splitting plate are two kinds of commonly used beam-splitting devices. However, which kind of the two devices degrade images to a less extent lacks discussion. Firstly, we theoretically analyzed possible image degradation caused by beam-splitting devices, which mainly include spherical aberration, ghost effect, a non-uniformity of the degradation function, and color cast. And we used ZEMAX optical simulation software to establish a beam-splitting imaging emulation experiment to simulate the image degradations mentioned above. we constructed an experience system of beam-splitting imaging in the laboratory. researchers could select a suitable device for their projects based on our study.
