1. Light Waves & Infrared Basics

Visible light (0.38-0.78μm) represents just a fraction of the electromagnetic spectrum. Beyond it lies infrared radiation (0.78-1000μm), categorized as:

• Near-infrared (0.78-2.0μm): Used in fiber optics

• Thermal infrared (2.0-1000μm): Emitted by all objects above -273°C, enabling heat detection

2. How Thermal Imaging Works

Unlike visible-light cameras:

• Thermal imagers detect inherent infrared radiation from objects

• Convert heat signatures into color-coded temperature maps

• Operate in complete darkness, smoke, or fog.

  Core advantage: Reveals invisible temperature differences (e.g., a 0.5°C inflammation hotspot).

3. Evolution: Military to Civilian Use

• 1940s: First infrared scopes developed for WWII night combat

• 1980s: Non-cooled microbolometers reduced costs by 90%

• 2000s: Miniaturization enabled consumer applications

• 2020s: Standard in medical screening and industrial maintenance

4. Key Applications

• Healthcare:

  
  

1. Inflammation mapping (e.g., breast cancer detection)

2. Real-time blood flow monitoring during surgery

• Industry:

  
  

1. Electrical fault detection (overheating components)

2. Predictive maintenance of machinery

• 
  

  Security:

  
  

1. Night vision for drones/vehicles

2. Perimeter surveillance
