Triton™: Active Imaging through Fog

Active imaging systems are used in degraded visual environments, like those found in marine fog and other areas with a high level of attenuation and scattering from obscurants like rain, smoke and dust. These systems are still limited in range and resolution. SA Photonics is taking advantage of new eyesafe, hybrid fiber-bulk laser technology capable of high pulse energy at high repetition rate to develop a scanning imaging lidar system capable of enhanced range in fog. In addition, this Triton™ lidar system will be capable of operation in the midwave infrared spectral region by frequency conversion of the laser using new nonlinear materials, allowing the system to operate at wavelengths with reduced scattering by fog. Operation of the system will be field-tested and performance for both transmitter wavelength ranges compared and optimized.
