Remote sensing with the world's most advanced spectral measurement technology The technology for non-contact observation of the shape and quality of an object from a remote location is known as remote sensing. When an object is exposed to electromagnetic waves (e.g. visible light, infrared rays, microwaves), some or all of the waves are repelled (reflection). The object itself can also emit electromagnetic waves into space. The properties of electromagnetic waves reflected or emitted by the object under examination depend on the status of the object or on the types of materials that make up the object. Therefore, it is possible to determine the shape and type of the object by receiving electromagnetic waves reflected or emitted from the object using a sensor on an artificial satellite, airplane or vehicle and analyzing their properties.
