| A cooled thermal camera's imaging sensor is integrated with a cryocooler. The cryocooler lowers the sensor temperature to cryogenic temperatures. This drop in sensor temperature is necessary to lessen thermally induced noise to a level below that of the signal from the scene being imaged. Cooled thermal cameras are more sensitive to small differences in scene temperature than are uncooled cameras, making cooled cameras more suitable for extremely long-range imaging in low-contrast scenes. The higher the thermal contrast, the easier it is to detect targets against a background that may not be much colder or hotter than the target. |
