Remote sensing using the world’s most advanced spectral measurement technology
Technology to observe the shape and nature of an object in a contactless manner from a remote location is known as remote sensing. When an object is irradiated with electromagnetic waves (e.g., visible light, infrared rays, microwaves), some or all of the waves are repelled (reflection). The object itself may also emit electromagnetic waves into space. Characteristics of electromagnetic waves reflected or emitted from the object being explore depend on the status of the object or types of materials composing the object. Therefore, it is possible to determine the shape and nature of the object by receiving electromagnetic waves reflected or emitted by the object using a sensor on an artificial satellite, aircraft or vehic
