True or false: Night vision devices are based upon IR sensors.Group of answer choicesTrueFalse

Answer: True

Night vision devices typically operate using infrared (IR) sensors. These sensors are designed to detect infrared radiation, which is not visible to the human eye but is emitted by objects based on their heat. There are two main types of night vision technology:

1. Image Intensification: This technology amplifies existing light (including near-infrared light) to create a visible image.
2. Thermal Imaging: This uses IR sensors to detect the heat emitted by objects, allowing users to see in the dark regardless of light levels.

Therefore, the statement that night vision devices are based upon IR sensors is true.
