| Back Surface Mirror | A mirror that has the metallic coating (called ‘silvering’) on the back surface of a piece of glass, to prevent scratching of the metallic surface. |
| | |
| Background- | The area within a scene that does not include the target of interest. |
| | |
| Bandwidth- | The range of frequencies over which a device is capable of operating within a specified performance limit. |
| | |
| Barium Strontium Titanate (BST) | A detector material often used in longwave, uncooled detectors. BST is particularly noted as a sensor material immune to solar radiation and other damaging high intensity infrared sources. |
| | |
| Black Hot | Infrared (‘thermal’) images are inherently grayscale images. Objects that give the strongest thermal signature can either be displayed as ‘black-hot’, meaning that the strongest thermal signature is displayed in black (or dark colors), or ‘white-hot’, meaning the strongest thermal signature would be displayed in white (or light colors). |
| | |
| Blackbody | A black body is a device that emits infrared radiation but does not transmit or reflect infrared radiation. A theoretical \\\"perfect emitter\\\" blackbodys in practical application are used to calibrate Infrared Cameras by presenting the camera with a known target that is constant in temperature and emissivity. Typical blackbodies are boxes with a heating element inside that have a large internal dimension compared to a small opening (hole) in the front at which the camera system is aimed. |
| | |
| Blackbody Radiation | The infrared energy emitted by a blackbody device for use in calibrating thermal camera systems. |
| | |
| Blooming | Image spreading and masking adjacent areas. This generally occurs in Infrared Sensors that do not hav ethe dynamic range to image the given scene and so the over or under parts of the image become highly saturated or \"Bloom\". |
| | |
| Bolometer | An infrared detector which absorbs the IR radiation and warms slightly; the electrical resistance across the bolometer changes as a function of temperature, which can be measured and calibrated. |
| | |
| BTU (British Thermal Unit) | In the English measuring system, the BTU is the unit of heat. One BTU is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. |
