There are a number of thermal imaging devices available on the market that are based on digital technology. These digital thermal imaging devices use an image intensifier tube to amplify light and create a clear image in low-light conditions. The image is then digitised and projected onto a display screen which can be viewed even in complete darkness.
These digital thermal imaging devices are designed for use in surveillance operations and can be used for a variety of applications, including nature observation, security, and surveillance. The digital technology used in these thermal imaging devices gives them a higher resolution than traditional thermal imaging devices and provides a clearer image in low light conditions.
