摘要：
State of the art IR-Imager in the near infrared spectral range for monitoring high temperatures in industrial applications are characterized by a number of small measurement ranges. Scenes with a high temperature contrast require several measures switching between these ranges and result in pictures with under range and saturated parts. A newly developed high temperature IR-Imager with a spectral range in the near infrared provides a wide dynamic range by utilizing specialized signal processing. A continuous temperature measurement range from 600 degrees C up to 1500 degrees C is realized with a resolution of 640x480 points and a measuring frequency of 25Hz. Each resulting image contains the full dynamic range and is transmitted via a Fast Ethernet interface in real time.
