LinOptx technologies: Enabling imaging through fog, smoke, heavy weather, and opaque material

1.  LinOptx technology modulates illuminations to distinguish backscattered and forward scattered light

2.  LinOptx technology employs neural networks to lock reflected information

Evaluation of LinOptx technologies

Detection through fog

Within a fog chamber of 6mx3mx2m (length x width x height), we demonstrated that, with our patented technique, we could obtain images of the targets with better contrast than at clear or in a no fog condition. 

Even though the visibility was greatly reduced to visually block targets, with our technique, we imaged through the glare to reveal the blocked targets clearly.

Even in conditions without fog, images taken with LinOptx technologies clearly show both

  • Higher contrast 
  • Higher quality

Image taken with LinOptx  technology

  • An image taken regularly (without LinOptx tech) shows only glare and doesn’t show any distinction of visible objects
  • LinOptx technology clearly distinguish the information of the target from the backscattered light
  • LinOptx technology also reveals the target behind dense, visually opaque fog
C++ controlled modulation

Real-time operations

Our techniques can be easily employed to form realtime imaging to track moving targets inside heavy fog. In light foggy conditions, every detail on a moving target were revealed clearly. In heavy fog, the clear outline of the moving target can be distinguished. We are developing modified techniques to see objects in clear detail in the extremely heavy fog conditions

With regular imaging (not using LinOptx technology) through fog @ 8meter visibility with normal illumination, an extremely low contrast image is produced

Applying LinOptx modulated illumination to achieve high-contrast images

With LinOptx technology, modulation of the inputs and processed with CNN at 8m visibility at the same exposures: a high contrast, easily distinguishable image is produced

This real-time image is @ 5 frames/s
