640x512 12μm Thermal Module Integration Guide
When developing firefighting helmets, night vision goggles, or FPV drones, the biggest challenge engineers face is the conflict between "image quality" and "payload." How do you obtain an image clear enough to identify a heat source 50 meters away without adding to a drone's power consumption or a helmet's weight?
The micro-thermal core is designed precisely for this purpose. Utilizing a VOx uncooled focal plane detector, it delivers high-definition 640x512 resolution while maintaining an ultra-compact size of 21x21x26.5mm.
Core Technical Q&A
1. Why is the 12μm pixel pitch critical for integrated devices?
Reducing the pixel pitch from the traditional 17μm to 12μm means more pixels can be packed into the same sensor size, or high resolution can be achieved on a smaller sensor. For the LX-U612PS, 12μm technology enables 640x512 resolution in a core weighing just 19g, significantly enhancing image detail in compact devices.
2. How does the LX-U612PS maintain image clarity in extreme environments?
The module features three internally developed algorithms:
- Smart AGC: Automatically adjusts contrast, ensuring target recognition even in scenes with minimal temperature differences.
- DDE (Digital Detail Enhancement): Sharpens image edges and textures.
- 3D Noise Reduction: Effectively filters out graininess for a clean video stream.
3. What is the performance of its temperature measurement?
The core supports auto-localization of full-screen max/min temperatures and center-point measurement. The range covers -20℃ to 150℃, making it ideal for power line inspections, industrial preventative maintenance, and search-and-rescue.
4. Which interfaces are available for secondary development?
To accommodate various processor platforms, the LX-U612PS offers a diverse range of interfaces:
- Digital Output: MIPI, BT656, UVC (supports plug-and-play via USB).
- Analog Output: CVBS (for traditional displays).
- Communication: UART (for sending control commands).
- SDK Support: A complete developer kit is provided to significantly shorten integration cycles.
