Thermal video sensors

Security robots with video surveillance were first used to patrol a large-scale sporting event at the World Cup in Berlin, Germany, in 2006 (Figure 17-17). The onboard video and thermal imaging sensors can send a live feed to a security office. The robot, OFRO, also uses global positioning system satellites to steer and keep accurate records of its exact location. Manufactured by Robowatch,... 

Fig. 1. Schematic for thermographic imaging. The ambient thermal radiation is imaged on the focal plane which converts the infrared to an electrical signal for display on a video monitor. Sensors with uncooled focal planes are now the size of a minicam and cost 5 to 10 times as much.
