Comparative Analysis of Approximation Functions for Spectral Characteristics of Serial Light Filters

We compute the errors which arise in the approximation of spectral characteristics of serial BPF type light filters, using various functions such as Gaussian, rational, and even-degree polynomials. The least error is obtained using spline approximations of low order (1–3), built from sampling of lig...

Zusammenfassung:We compute the errors which arise in the approximation of spectral characteristics of serial BPF type light filters, using various functions such as Gaussian, rational, and even-degree polynomials. The least error is obtained using spline approximations of low order (1–3), built from sampling of light filter table data.
