Background signal
| Глоссарий по инфракрасному и термическому контролю |
Steady or fluctuating output signal of a test instrument caused by the presence of acoustic, chemical, electrical or radiation conditions to which the sensing element responds.1 background temperature, instrument: apparent ambient temperature of the scene behind and surrounding the instrument, as viewed from the target. the reflection of this background may appear in the image and affect the temperature measurement. most quantitative thermal sensing and imaging instruments provide a means for correcting measurements for this reflection.3 background temperature, target: apparent ambient temperature of the scene behind and surrounding the instrument, as viewed from the instrument. when the fov of a point sensing instrument is larger than the target, the target background temperature will affect the instrument reading.3 backscattering, infrared: reflection of thermal energy — e.g., generated by the ground and reflecting off the underside of clouds or inversion layers, or unwanted front surface reflections from a transparent optical element.
