Extracting sub-exposure images from a single capture through Fourier-based optical modulation

作者：

Highlights：

•

• A sub-exposure image extraction method based on coded exposure is proposed.

• The exposure coding pattern is inspired from frequency division multiplexing.

• Sub-exposure images are placed in nonoverlapping regions in Fourier domain.

• The extraction involves filtering of captured signal with proper bandpass filters.

• A prototype imaging system is implemented with an LCoS SLM.
