Fig. 4From: Energy balance in Spectral Filter Array camera designA set of Gaussian filters where N=3, \(\mu _{i}=\lambda _{min}+\frac {\Delta \Lambda (2i-1) }{2N}\), \(\sigma = \frac {\Delta \Lambda }{N \times 4}\) and B i =1. The gaussians are spaced by 4σ and the intersection between two is at ±2σ Back to article page
