WHAT IS LIDAR?

The term LIDAR is an acronym for Light Detection And Ranging (or a portmanteau of “light” and “radar,” depending who you ask). LIDAR devices measure distances by illuminating a target with a laser and interpreting the results from the reflected light. These distance measurements can be used for all sorts of applications such as scanning objec... (read more)

Infrared lasers can also be used in temperature measuring. Devices can aim infrared laser light at an object and measure the electromagnetic radiation emitted from the object’s surface. This is useful in situations where a contact-digital-thermometer would be dangerous or difficult to use, such as measuring the temperature of a car’s engine or of food on a grill.
