Eye Imaging Technology

As we know, robotic eyes are very different in that they do not have retina, so to help them interact with the world more effectively are the optical coherence tomography (OCT) devices commonly found in the eye doctor’s office. One of the most common eye imaging technologies included in most sensory packages is light detection and range, we also know it as LiDAR.

Autonomous car developers are investing exponentially in LiDAR technologies because it works like radar, but instead of sending wide waves and seeking reflection, it uses short pulses of light from the lasers. But using traditional forms of LiDAR technologies can be challenging, as it requires detection of very weak reflected light signals. Other LiDAR systems, sometimes even soft sunlight, can make the system sensitive. To address these challenges, researchers have turned to another form of LiDAR technology known as frequency-modulated continuous-wave LiDAR.

The FMCW LiDAR takes a similar approach, but with its own characteristics. It is more advanced in its approach and can effectively distinguish between different frequencies and light sources. Integrating this technology into robots and autonomous cars can greatly enhance their visionary capabilities.
