【摘要】：基于稀疏約束的鬼成像光譜相機,能夠通過單次曝光獲得目標場景的三維空間光譜數(shù)據(jù)立方體。但是由于不同波長的散斑場在探測器的同一位置處,使得儀器的光譜分辨率和信噪比受到限制。為了解決上述問題,提出了利用平場光柵分光將不同波長的光場在探測面上錯開一定距離的系統(tǒng),實現(xiàn)了基于平場光柵的稀疏約束鬼成像高光譜相機。通過對系統(tǒng)成像過程的理論推導,得到了系統(tǒng)的關聯(lián)函數(shù),并通過實驗和數(shù)值模擬驗證了理論推導結果。在保證原先光譜相機優(yōu)點的同時,基于稀疏約束的鬼成像高光譜相機可以分別調(diào)控光譜分辨率和空間分辨率,實現(xiàn)可控的信噪比。此外,還能夠根據(jù)不同波長的光場特性來優(yōu)化測量矩陣,從而提高圖像恢復質(zhì)量。
[Abstract]:The ghost imaging spectral camera based on sparse constraints can obtain the three-dimensional spatial spectral data cube of the target scene by single exposure. However, the spectral resolution and signal to noise ratio of the instrument are limited because the speckle fields of different wavelengths are in the same position. In order to solve the above problems, a flat field grating is proposed. The sparse constrained ghost imaging hyperspectral camera based on the flat field grating is realized by using the light field of different wavelengths on the detection surface. The correlation function of the system is obtained by theoretical derivation of the system imaging process. The theoretical derivation is verified by experiments and numerical simulations. At the same time, the ghost imaging hyperspectral camera based on sparse constraints can control spectral resolution and spatial resolution to achieve a controllable signal to noise ratio. In addition, the measurement matrix can be optimized according to the optical field characteristics of different wavelengths, thus improving the quality of image recovery.
