Spectral imaging system and method employing an acousto-optic tunable filter for wavelength sele |
October 27, 1998 |
| An acousto-optic tunable filter (AOTF) has one or more optical wavelength passbands dependent on the frequency or frequencies of a radio frequency signal applied thereto. A radio frequency generator applies the radio frequency signal under computer control of the RF frequency so that the |
