US 2009/0153658 A1 · VIDEO AND THERMAL IMAGING SYSTEM FOR MONITORING INTERIORS OF HIGH TEMPERATURE REACTION VESSELS

Abstract

A system and method for real-time monitoring of the interior of a combustor or gasifier wherein light emitted by the interior surface of a refractory wall of the combustor or gasifier is collected using an imaging fiber optic bundle having a light receiving end and a light output end. Color information in the light is captured with primary color (RGB) filters or complimentary color (GMCY) filters placed over individual pixels of color sensors disposed within a digital color camera in a BAYER mosaic layout, producing RGB signal outputs or GMCY signal outputs. The signal outputs are processed using intensity ratios of the primary color filters or the complimentary color filters, producing video images and/or thermal images of the interior of the combustor or gasifier.

Dependent claims

An imaging system for real-time monitoring of an interior of a high temperature reaction vessel comprising:

an imaging fiber optic bundle having a light receiving end and a light output end;
a digital color camera comprising one of CCD and CMOS sensors and having a light receiving inlet in light transmission communication with said light output end and comprising one of primary color (RGB) and complimentary color (GMCY) filters placed over individual pixels of said sensors within said digital color camera in a BAYER mosaic layout;
focusing means for focusing light to be received by said light receiving end of said imaging fiber optic bundle, said focusing means comprising a wall disposed between said light receiving end and a light source, said wall forming a pinhole opening aligned with said light receiving end;
and
processing means for processing said light received by said individual pixels to produce at least one of a video image and a thermal image of said interior of said high temperature reaction vessel.
