Definition

A technology that uses laser light to measure distances and detect objects by analyzing the light that bounces back from them.

Example

The researchers used lidar to create a detailed map of the forest.

Conversation

Have you heard about how lidar technology is changing mapping?

Yeah, it's fascinating how it works with laser light!

I read that it can create super detailed 3D models of landscapes.

Exactly! It's amazing for things like self-driving cars too.

Root Explanation

Lidar is formed from "light" (meaning electromagnetic radiation visible to the human eye) and "radar" (from radio detection and ranging, meaning to detect and determine the distance of objects using radio waves). The term lidar refers to a technology that uses light to detect and measure distances to objects.

Memory Tip

Think of using 'light' to 'detect' distances, just like radar does with radio waves. This helps you remember that lidar is a technology that measures distances using light.
