Zoom optical system design for acousto-optic tunable filter camera assisted by programming multidimensional analysis

Abstract

A medium infrared 1 2 × continuous zoom optical system serving for an acousto-optic tunable filter spectral camera has been designed covering a 25–300 mm zooming range. Instead of relying on past experience for roughly determining the initial optical structure, a simulation programming based on Gaussian principle has been composed via MATLAB to accurately calculate the initial designing parameters, which is confirmed to be extremely close to the optimized results using Zemax. The relative design results have been multidimensionally analyzed in detail, which offers fresh thinking for future zoom optical design covering broadband operation wave band.
