Abstract

We develop herein a new optimization modulation method for the three-dimensional (3D) spectral data cubes (SDC) based on the use of a linear encoding scheme of the intrinsic chromatic aberration, especially for snapshot multispectral or hyperspectral imaging systems. The mathematical model of the linear chromatic aberration modulation is established that provides the theoretical guidelines on the optimal design of 3D SDC for snapshot spectral imaging systems. Theoretical calculations and spectral simulations of an optical system are conducted and are shown to match closely, thus demonstrating that the proposed linear encoding scheme can be used as a valid modulation method for 3D SDC. This study also addresses the mutual restriction of spectral and spatial resolutions in the studied imaging systems. Overall, the proposed method is expected to create new possibilities for high-resolution, low-cost spectral imaging with simple designs.
