Lesson 1: Introduction to Thermal Imaging and FLIR Systems

Welcome to the foundational lesson of our course on mastering FLIR thermal imaging cameras. Before we dive into the specifics of operating your device, it is crucial to establish a strong theoretical understanding of what thermal imaging is, how it works, and the specific role FLIR plays in this industry.

1.1 What is Thermal Imaging?

Thermal imaging, or infrared (IR) thermography, is a non-contact measurement technique that captures the infrared energy emitted by all objects above absolute zero (0 Kelvin). This emitted energy is invisible to the naked human eye, which only perceives the visible light spectrum (approximately 0.4 to 0.7 micrometers).
