ToF, short for Time of Flight.

This technology measures the time taken by an object which it takes an emitted light hit the object and then be reflected off of an object.　This technology holds significant potential across various industries, particularly in autonomous driving, where precise distance measurement is critical for safety and navigation.

LiDAR (Light Detection and Ranging)

LiDAR uses laser to determine ranges and measure the time for the reflected light to return to the receiver. It is also used to measure the distance, 3D mappings, Automotive, mobile sensing system, etc.

Both ToF and LiDAR are foundational technologies for modern sensing applications, offering high precision and reliability in dynamic environments.

ToF / LiDAR Evaluation System Overview

A typical ToF (Time of Flight) or LiDAR evaluation system is designed to assess the performance and accuracy of distance-measuring sensors. The system generally consists of the following key components:

• Near-infrared (NIR) light source

• Chart stand (used for placing reflectance targets or test charts)

• Movable rail system

• Darkroom environment

The near-infrared wavelength range commonly used in ToF applications is 850 nm or 940 nm, which provides optimal balance between sensor sensitivity and eye safety.

This type of evaluation setup is essential for validating sensor performance under controlled conditions and is widely used in the development of autonomous driving systems, robotics, 3D cameras, and other depth-sensing technologies.
