What is remote sensing?

ASD Document 600540 Rev. J
FieldSpec - is a general-purpose spectrometer specifically designed for field
environmental remote sensing. The FieldSpec is a spectroradiometer in
that it is calibrated to be able to perform radiance and irradiance
measurements, as well as reflectance and transmittance. The fiberoptic
cable is routed through the front panel and is fixed to the internal
spectrometers, which provides a superior signal-to-noise ratio than the
other ASD spectrometers with detachable fiberoptic cables. (The
FieldSpec spectrometer can also be specially ordered as a high-resolution
instrument, the main TerraSpec feature.)
TerraSpec - is a high-resolution spectrometer specially designed for mining
and geology applications. It is ideally suited for performing reflectance
spectral measurements of rocks, minerals, and core samples. Its higher
resolution is optimized for samples that have high absorption features.
The Hi-Brite MugLite and Hi-Brite Contact Probe are designed to work
with this spectrometer.
AgriSpec - is a general-purpose spectrometer designed for agriculture and the
field analysis of vegetation and soils. Its resolution is ideally suited for
performing reflectance and transmittance spectral measurements of
samples that have broad absorptions features. This spectrometer can use
nearly all of the accessories containing a light source, such as the plant
probe and leaf clip.
LabSpec - is a general-purpose spectrometer designed not only for laboratory
analysis, but also for the plant floor, receiving, and even field work. It is
meant to be portable for multiple uses requiring visible and near infrared
reflectance, transmission, or absorbance to analyze and identify materials.
The LabSpec is similar to the AgriSpec. The LabSpec 2500 has a 10 nm
resolution, while the LabSpec 2600 has a 6 nm resolution.
QualitySpec - is a general-purpose spectrometer specifically designed for
material analysis and identification in the laboratory. The QualitySpec
features are equivalent to the AgriSpec except that it is not field-portable.
Remote sensing is defined as the art and science of obtaining information
about an object without being in direct physical contact with the object.
The ASD spectrometers achieve this using visible near-infrared (VNIR) and
short-wave infrared (SWIR) spectra.
