Introduction to Thermal Imaging

Thermal imaging technology detects infrared radiation and provides images based on temperature differences. This technology is crucial in various applications, including surveillance, firefighting, and industrial inspections.

Components of Fixed Lens Thermal Cameras

Fixed lens thermal cameras are equipped with key components that ensure their functionality:

• Optical Lens: Usually made of germanium or chalcogenide glass due to their infrared transparency.
• Infrared Detector: Converts thermal radiation into electrical signals.
• Signal Processor: Processes the electrical signals to generate a thermal image.
• Display System: Outputs the thermal image for analysis.

Operational Principles of Fixed Lens Thermal Cameras

Fixed lens thermal cameras work by detecting infrared radiation emitted by objects. These cameras focus the infrared energy onto a detector array, which then converts it into an electronic signal. This signal is processed to form an image that represents the temperature distribution across the scene.

Performance Parameters

The performance of fixed lens thermal cameras can be quantified by several parameters:

• Resolution: Typically ranges from 160x120 to 640x480 pixels.
• Thermal Sensitivity: Also known as Noise Equivalent Temperature Difference (NETD), usually less than 50mK.
• Field of View (FOV): Dependent on the lens, common values range from 10° to 60°.
• Frame Rate: Can vary from 9Hz for basic applications to 60Hz for real-time analysis.
