Thermal Night Vision Camera (Thermal Camera)
Thermal Camera IFOV - Instantaneous Field of View (Spatial Resolution)
The thermal camera is an advanced camera that detects differences in the A measurement of a sensor's intrinsic field of view corresponding to the
infrared energy of objects and the background, converts them into electric amount of light that a sensor can detect at an instant : the smaller it is, the
signals, and produces digital images. fuller an image looks with longer detection distance.
Signal Processor D
Infrared Detector
Optics = d/D (mrad)
Infrared Energy d IFOV
Scene
Monitor IFOV = d/D mrad
(ex) IFOV=23.5μm/14mm=1.68mrad
NETD (Noise Equivalent Temperature Difference)
NETD is a measurement of the smallest temperature difference that a
thermal imaging camera can detect an object clearly.
Thermal Cameras Vs. Visible Cameras Color Pattern
In comparison to a visible camera, it is possible to detect objects up to With the color pattern function, it is easy to detect the temperatures of the
1km (0.6miles) away in total darkness and through rain, fog or heavy objects. It is possible to differentiate the temperature range of an object.
