Paper Abstract
Coded aperture spectral imaging is a new system to captures multiframes images and reconstructs them into spectral
image cube based on compressive sensing theory (CS). However, using dynamic transformed coded aperture pattern can
cause two primary problems, firstly the whole exposure procedure needs to be staring on the same surface feature which
is depended on a high quality stable platform; secondly the coded aperture’s transformation might reduce the system’s
stability. To avoid these problems without a loss of information for precise reconstruction, in the paper we propose
dividing the single image panel into encoding spatial overlapped sub-districts. We design a pushbroom scan pattern to
ensure each sub-district have enough sampling measurements. In each sub-district, we infer its measurement matrix can
satisfy the sparsely requirements needed for accurate estimation and final reconstruction with CS sampling. Considering
with efficiency and accuracy, we design a orthogonal self-loop coding mask (lines irrelevant) to guarantee the coding are
irrelevant among distinct snapshot of the same scene. The simulation experiment reveals the design helping reconstruct
the scene spectral cube with high throughput and resolution.
