Multispectral Camera
Multispectral Camera
Thermal imaging, operating at long-wave infrared wavelengths, is important for a wide range of room temperature applications. However, cameras at this wavelength are expensive compared to typical visible wavelength cameras. I built a multispectral camera that captures a high-resolution visible image to enhance a low-resolution thermal image at a fraction of the cost of higher-end thermal cameras.
