What Is Thermal Imaging; Vehicles That Use Pathfindir Ii - FLIR PathFindIR II User Manual

2 – Introduction

2.3 What is Thermal Imaging?

With our eyes, we see visible light. With a thermal imager, we can see infrared thermal energy - a
form of light just beyond the visible spectrum. Thermal imagers show subtle differences in
temperature; warm objects appear white and cooler objects appear black.
In addition to driver vision enhancement, FLIR's thermal imaging cameras are used in a wide variety
of applications, including fire fighting, security, maritime, traffic safety, industrial and medical
applications. They continue to be used by militaries worldwide to navigate at night and in battlefield
conditions. Over the last few years, volume production of these systems has allowed FLIR to offer
the same high performance cameras designed for military use to the commercial market.
Although adverse conditions such as heavy fog will affect any driver vision enhancement system,
thermal imaging cameras such as the PathFindIR II have been shown to continue to provide useful
information in conditions of reduced visibility, such as haze and smoke. While the PathFindIR II can
assist drivers with detection of obstructions in the vehicle's path, thermal imagers should not be
used as the sole vision method of the driver.
PathFindIR II is specifically designed to withstand a harsh environment, with a hermetically-sealed
external housing resistant to rocks, sand, salt, and under-hood contaminants. Additionally, the wide
operating temperature range allows the PathFindIR II to maintain high performance in severe
weather conditions.

2.4 Vehicles that use PathFindIR II

Passenger Vehicles, Commercial Trucks, Buses, and Recreational Vehicles - PathFindIR II can
reduce the detection time for hazards and reduce the probability of an accident - saving lives,
property, and profits.
Emergency Vehicles - Emergency vehicles' high speeds and degraded stopping distances increase
the chance of an accident - PathFindIR II improves hazard detection at high speeds.
Commuter and Freight Trains - PathFindIR II can reveal railway obstructions at long ranges in
complete darkness. This early detection capability can significantly increase reaction time
depending on the size of the obstruction.
Heavy Construction Vehicles - For heavy equipment navigation, PathFindIR II improves awareness
in conditions that render eyesight and daylight cameras useless. The PathFindIR II can see clearly
through dust and smoke, increasing safety for everyone on the job site.
