Patent ID: 7453064

Claim:
A dual-band reflective infrared thermal imaging system, comprising: an infrared thermal imager; and a visible light video camera disposed at a central axis of the infrared thermal imager, so that the infrared thermal imager and the visible light video camera take infrared images and visible light images coaxially, wherein the infrared thermal imager further comprises: a reflective optical module further comprising a first reflector with a first infrared reflective layer and a second reflector with a second infrared reflective layer; an infrared imaging sensor for capturing the infrared images reflected by the reflective optical module and focused on the infrared imaging sensor; and a focusing module further comprising: a fixing plate for fixing the visible light video camera and the second reflector; steel balls coupling the fixing plate to a shell of the infrared thermal imager so that the fixing plate is able to move on the shell; and a fixing device fixing the fixing plate on the shell.
