This video, presented by Optris's head of marketing, provides an essential guide to understanding the optical resolution of thermal imagers.
It is a deep dive into key technical terms that every professional should know, including:
Field of View (FOV): The overall angle a device can detect a target.
Instantaneous Field of View (IFOV): The smallest object size a single pixel can resolve.
Measurement Field of View (MFOV): The minimum target size needed to ensure accurate temperature readings, typically defined as a 3x3 or 4x4 pixel area.
F Number: A measure of the optics' aperture, which affects the amount of energy that reaches the detector.
The video uses practical examples to demonstrate that a high pixel count alone does not guarantee accurate temperature readings. It emphasizes that MFOV is the most critical factor for precise measurements and shows how a low-resolution camera can provide completely inaccurate data when measuring a small object.
If you're selecting a thermal imager, this video is a must-watch to ensure you make an informed decision based on more than just pixel count.
