Abstract
Since the energy of the incident light is constant, the spatial and spectral resolution can hardly be improved without scarifying the other with the spectral imaging method of a pushbroom scanner. Thus, a new spectral imaging method is proposed to obtain a high-resolution (HR) spectral image with a low-resolution detector array. The method, namely coded dispersion, by which compressive measurement is achieved, improves light collection efficiency, and then a high-quality reconstructed HR spectral image is obtained with fewer sensors. The simulation result shows that with prior knowledge of scenes available, the proposed method also offers a new way to acquire an HR spectral image while the density of detector array is constrained by battery, capacity, transmission bandwidth, and cost.
