Honeywell has developed a spectrally agile infrared filter based on the dual tunable Fabry-Perot (DTFP) concept. A DTFP transmits broad or narrow spectral bands which are tunable over a large spectral range. Harmonic spectral transmission can be eliminated by maintaining staggered cavity orders. Several DTFP filters have been fabricated and tested. A closed-loop, capacitive control system is used to adjust plate alignment and spacing. DTFP transmission greater than 0.8 and drive and stabilization times of less than 4.0 milliseconds have been demonstrated. DTFP design considerations and experimental performance data will be discussed.
