The invention discloses a two-channel
remote sensing light spectrum imaging
system based on
compressed sensing, and an imaging method, and mainly solves the problems, in the prior art, that the utilization ratio of
light spectrum information is low, the difficulty in manufacturing technique of a
detector is high,
high spatial resolution and high
spectral resolution of
spectrogram image can not be obtained at the same time. The imaging
system comprises a beamsplitter module (1), a first observing passage module (2), a second observing passage module (3), and an image reconstructing and
processing module (4). Original
spectrogram images are divided into two paths of light beams which are the same in information and different in directions, the first observing passage module (2) and the second observing passage module (3) achieve complementary coding observation to the
light spectrum image, observed results are output to the image reconstructing and
processing module (4), a reconstruction model of the
spectrogram image is built, and the original spectrogram images are reconstructed by using a nonlinear optimized method. The invention has the advantages that the utilization ratio of the light spectrum information is high, the manufacturing technique is simple, and the calculation complex rate is low, thereby being used for acquiring and reconstructing
remote sensing spectrogram images.
