Table 1.

The performance of the proposed HSI device and the more comparable HSI devices found in the literature. A cell is blank when the parameter is not available in its related paper. $|\lambda |$ is the number of wavebands. The column One Shot has a tick mark when the HSI device extracts a hypercube from a single digital image. The OM column has a cross mark when the HSI device posses optomechanical parts or, it uses the whisk-broom technique to acquire hypercubes. The column SW has a tick mark when the authors deployed the required software to calibrate and obtain hypercubes.
