![]() Changes which are too small to be distinguished from the background noise in the system will not be detected. The smallest temperature difference a system can detect (and therefore can display differently) is called the thermal resolution. For infrared imaging systems, which detect the thermal radiation from objects, an important measure of performance is its ability to detect small changes in temperature. The spatial extent of the IFOV at object range R is estimated (for small angles) by height: Dh R x VIFOV width: Dw R x HIFOV. For example, if the IFOV = 1 mrad, then at 1000 m, the instantaneous field-of-view will cover 1 m in length. For an object at some range, R, from the detector, the IFOV will encompass some length. The depth of focus is the effective distance over which satisfactory cutting can be achieved. The critical factors which govern the efficiency of the process are the focused spot diameter (d) and the depth of focus (L). There may be different vertical (VIFOV) and horizontal (HIFOV) instantaneous fields-of-view. The lens is defined by its focal length, which is the distance from the lens to the focused spot. Data from these scenes are used to study Earths dynamic features such as volcanoes, measure land surface temperature, create detailed elevation maps. and add jars from it’s download location then click -> Apply and Close. The smallest image element is determined by the IFOV. Right Click on MyProject -> then select Build Path -> Click on Configure Build Path and select Add External jars. The IR camera has an in-built temperature detector (at least most recent models) that compensates for detector and system heat build up. The spatial resolution of an imaging system is its ability to distinguish separate objects or parts of an object within its field-of-view. ![]()
