Figures & Tables
Fig. 1. System schematic diagram. The imaging process of a data cube, and its procedure of the down sampling and dispersive optical model.
Fig. 3. Simulated diagrams of the system in Zemax. (a) The 2D layout of the final optical system. (b) The spot diagram of the system for different fields of view and different wavelengths.
Fig. 4. F number match diagram. (a) The F number of the objective is greater than the microlens F number, which causes gaps. (b) The F number of the objective lens is less than the microlens F number, which causes overlaps.
Fig. 6. Diagram of the experimental setup. (a) The overall view of the setup. (b) The inside details of the key parts.
Fig. 7. Images of the whiteboard at different wavelengths. (a) 514.5 nm. (b) 560 nm. (c) 632.8 nm.
Fig. 8. Experimental result. (a) The original graph. (b) The image of the original graph through the system.
