SURFACE AND PARTICLE IMAGING PYROMETER AND METHOD |
摘要 |
An optical pyrometer and method of use provides a dual path optical system (20) for processing light from a radiating stationary object (17) or a moving thermal stream. Light is collected by primary optics (1) forming an intermediate image in a plane of a field limiting aperture (2) for establishing a preferred field of view. The light is then split into a pair of complementary beams with one beam directed through a long wavelength filter (4) and the other directed through a short wavelength filter (5). Both beams then move through separate secondary optics (9, 10) and are then rejoined and directed as normal non-overlapping and adjacent images onto a digitizing detector (16) for capturing the images. Signals from the detector (16) are handled by a computer where a ratio mapping of pair of signals from corresponding points on the two images is constructed and displayed on a monitor (70) for viewing a temperature map of the object or thermal stream. The temperature of particles in the thermal stream is determined in a similar manner as well as particle velocity and size.
