Remote sensing
multispectral scanner
Earth science; Remote sensing
Scanner system that simultaneously acquires images of the same scene at different wavelengths.
rods
Earth science; Remote sensing
The receptors in the retina that are sensitive to brightness variations.
charge-coupled detector (CCD)
Earth science; Remote sensing
A device in which electron are stored at the surface of a semiconductor.
fovea
Earth science; Remote sensing
The region around that point on the retina intersected by the eye's optic axis, where receptors are most densely packed. It is the most sensitive part of the retina.
point spread function (PSF)
Earth science; Remote sensing
The image of a point source of radiation, such as a star, collected by an imaging device. A measure of the spatial fidelity of the device.
chlorosis
Earth science; Remote sensing
Yellowing of plant leaves resulting from an imbalance in the iron metabolism caused by excess concentrations of copper, zinc, manganese, or other elements in the plant.
radar altimeter
Earth science; Remote sensing
A non-imaging device that records the time of radar returns from vertically beneath a platform to estimate the distance to and hence the elevation of the surface; carried by Seasat and the EAS-ERS-1 ...
