Infrared cameras enhance machine-vision systems

摘要

Engineers and system integrators are becoming increasingly familiar with the capabilities offered by IR technology, its unique system parameters, and the factors that have to be reviewed when selecting an IR machine-vision camera. In addition to common optical aspects of a machine-vision system such as the field of view and spatial resolution, IR systems nave two unique parameters: thermal resolution and spectral range. Thermal resolution (or contrast) measures the ability to distinguish changes in temperature.
