High Resolution Imaging
More than Adaptive Optics
Looking through the Earth’s atmosphere always results in distortion and blurring of the image. The best technology to overcome the degradation is adaptive optics, which can restore image quality limited only by the physics of diffraction. For a host of applications though, the technology is either infeasible or unnecessary. Scenarios with strong turbulence and low light levels, imaging from space, and traditional imaging where an entire adaptive optics system is simply impractical are all cases where alternative approaches are better suited. HartSCI is a pioneer in the creation of image restoration algorithms that exploit information from additional sensors in more sophisticated systems to enable the imaging systems you decide to take out of your lab space and into the real world.
Removing blur algorithmically
In regimes of high turbulence and low signal such as daylight satellite imaging systems, traditional adaptive optics tend to fail. We have developed unique capabilities to mitigate nature's effects on light hitting your detector. Using proprietary techniques developed for both blind and myopic deconvolution scenarios, we are able to achieve high-resolution imagery with the DORA algorithm being a flagship of technical ability.
Hubble Space Telescope Restoration
Shown top is the upward looking atmospherically blurred image of the Hubble space telescope where little to no structure is visible. This is in despite of the 3.6 meter collecting aperture and a pristine mountain site naturally equipped with laminar airflow. Below is the same scene restored showing significant structure of the telescope tube as well as the faint outlines of the radiation shield and solar panels.
The same techniques on laterally blurred images from heat shimmer. The resolution achieved enables identification of the ever popular TGI Fridays and the unique identification of individuals.
High Resolution Design
For ground-based observatories, the vast majority of optical turbulence is closest to the ground and this paradigm drove an entire methodology in adaptive optics correction. If however you are looking down, above earths atmosphere, and in-orbit the same adverse effects of optical scintillation across your aperture are negligible to a large degree, at least for the size of optics flown in space. In these instances of downward imaging, the use of adaptive optics is unnecessary and even impractical. Instead the strong design of your optics is paramount such as our SIRII imaging platform designed outward to provide the clarity needed for decision making.
