Thermal imaging camera device
An improved camera system includes an uncooled thermal imaging sensor, a rotary actuator, a rotary encoder, and a slip ring. The rotary actuator is physically coupled to the uncooled thermal imaging sensor and enables the sensor to rotate a full 360 degrees any number of times relative to the system's horizontal base. Through the use of the slip ring, the sensor and the sensor's wiring can rotate freely without impedance. Notably, the sensor's wiring can be disposed through a central through-hole running the length of the rotary actuator. Therefore, prior to reaching the slip ring, the sensor and its wiring rotate in unison with the rotary actuator. The encoder is structured to monitor the angular position of the sensor in order to accurately determine where the sensor is being aimed.
