Definitions
- the Brady team at Duke University in the United States combines perceptual sensing with spectral imaging to achieve quasi-single-shot compression-spectrum imaging based on an amplitude mask. It first images the object on the first imaging surface, and places a binary amplitude mask on the imaging surface to amplitude modulate the image of the object. The modulated image is imaged on the second imaging surface through a beam splitting prism, and the second imaging surface is detected by the area array detector.
- this imaging spectrometer global projection measurements are performed only in the spectral dimension and compression acquisition is achieved. Global projection measurements are not used in spatial dimensions, so compression acquisition is not implemented in spatial dimensions.
- the system achieves a higher spatial resolution by moving the amplitude mask, and also based on amplitude modulation, the light energy utilization is low.
- each branch a ⁇ conversion system, a random grating and a photoelectric detection system are arranged in turn, and all the photoelectric detection systems and meters
- the computer is connected, and the exit and exit conversion system of each branch is located on the imaging surface of the branch through the front imaging system, and the random grating of each branch is located at the exit of the front imaging system.
- the photodetection system of each of the branches is located behind the random grating of the branch through the imaging plane behind the exit and exit conversion system of the branch.
- the system realizes the further compression acquisition of the image data of the spectral dimension by utilizing the correlation between adjacent spectra, and further reduces the data collection amount, thereby further Reduces the number of detector pixels and measurement time requirements. Moreover, the dispersion effect of the random grating on the light field further improves the spectral resolution of the system.
- the exit and exit conversion system adopted by the system greatly increases the imaging range of the system.
- the exit and exit conversion system of each branch images the exit pupil of the front imaging system onto the random grating of the branch, so that the light fields incident in all directions pass through the center of the random grating without increasing the number of detected pixels. Increased imaging range of the system.
- the exit conversion system 3 The object 1 is located on the imaging surface 3 of the branch through the pre-imaging system 1 , and the random grating 4 is located on the imaging surface of the exit pupil 2 of the pre-imaging system through the exit/exit conversion system 3 of the branch, the photodetector 5 Located at a distance from the random grating 4 of the branch.
- the exit pupil conversion system 7 is located on the imaging surface 5 of the branch through the pre-imaging system 1 of the object 1 and the random grating 8 is located at the exit pupil 2 of the pre-imaging system through the exit and exit system of the branch
- the photodetector 9 is located a distance behind the random grating 8 of the branch.
