Optics, a small word, yet a powerful game changer in the world of LiDAR.

There are several elements in any machine or device that makes it work. People generally have this misconception that the laser, detector or signal processing unit is the most important component of a LiDAR…

Eye safety: Where technology meets biology

Eye safety: Where technology meets biology

Philip Constantine

Eye safety (and general biological safety) is of paramount importance when designing any laser-based system.  

But, as with many other aspects of design, ensuring eye safety isn’t a simple or linear process. To the contrary, there are a number of factors to be considered, many of them appearing to be contradictory. And that’s why it’s best to consider this response before designing a LiDAR sensor, and then work back from there, determining the parameters which may have the greatest effect. 

LiDAR rules the machine perception space!!

LiDAR rules the machine perception space!!

Many machines need to be aware of the objects and spaces around them. This might be to detect when something arrives or leaves, to measure how high something is or to see how far away an obstacle is. It is the position of things relative to the machine that affects the decisions that the machine must make. Human centric visual characteristics are not important to a machine. It is the pure logical concepts of presence, absence and position that determine what actions must be taken. This is where lidar excels as it clearly identifies objects and can measure the spaces between them.
Electron <-> photon conversion

Electron <-> photon conversion

Here’s a riddle: what gets lost every time you gain? The answer? Electrons and photons – when you’re converting electricity, that is.
