Using a hemispherical mirror for an all-sky thermal camera system is a clever approach to achieve a 360\u00b0 field of view. Here’s how it typically works:<\/p>\n<\/div>\n

\n
    \n
  1. Setup<\/strong>: The thermal camera is positioned to look downward at the hemispherical mirror. The mirror reflects the entire sky into the camera’s lens, allowing it to capture a full view of the sky.<\/li>\n
  2. Advantages<\/strong>:\n
      \n
    • This setup is cost-effective compared to using ultra-wide-angle lenses.<\/li>\n
    • It provides a compact design for capturing a large field of view.<\/li>\n
    • The mirror can be made from materials that are durable and weather-resistant, suitable for outdoor use.<\/li>\n<\/ul>\n<\/li>\n
    • Considerations<\/strong>:\n
        \n
      • The quality of the mirror’s surface is crucial for accurate imaging. Any imperfections can distort the reflected image.<\/li>\n
      • Calibration is necessary to correct for distortions introduced by the mirror’s curvature.<\/li>\n
      • The thermal camera’s sensitivity and resolution should match the requirements of your application, such as cloud tracking or atmospheric studies.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<\/div>\n

        For your all-sky thermal camera system, here are some recommendations for both the hemispherical mirror and the thermal camera:<\/p>\n

        Hemispherical Mirror<\/strong><\/h3>\n
          \n
        • Material<\/strong>: Look for a high-quality, polished metal or coated glass mirror. These materials ensure good reflectivity and durability.<\/li>\n
        • Size<\/strong>: The size of the mirror depends on your camera’s field of view. A larger mirror provides a wider reflection but requires precise alignment.<\/li>\n
        • Vendors<\/strong>: Companies like Edmund Optics or Thorlabs offer a range of optical mirrors that could work for your setup. You might also explore DIY options using polished stainless steel or acrylic domes.<\/li>\n<\/ul>\n

          Thermal Camera<\/strong><\/h3>\n
            \n
          • FLIR E8-XT<\/strong>: This camera offers a high resolution (320 x 240 pixels) and Wi-Fi connectivity, making it suitable for capturing detailed thermal images.<\/li>\n
          • Bosch GTC 600 C<\/strong>: A robust option with a wide temperature range (-20\u00b0C to +600\u00b0C) and excellent thermal resolution.<\/li>\n
          • Trotec IC300<\/strong>: Known for its real-time display and high sensitivity (0.05\u00b0C), this camera is ideal for precise thermal imaging.<\/li>\n<\/ul>\n

            Considerations<\/strong><\/h3>\n
              \n
            • Ensure the camera’s resolution and sensitivity match your requirements for sky observation.<\/li>\n
            • The mirror and camera should be compatible in terms of field of view and alignment.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
