Technical Note: Linearity
Linearity as it relates to CCD technology refers to the relationship between incoming light and the output signal. This signal can be in analog or digital form after the primary light to charge conversion. High performance CCD image sensors exhibit a high quality of linearity, whereas their predecessor video CCD based and other solid-state image sensors do not. Excellent linearity is particularly important in quantitative imaging for ratio calculations, flat field corrections and linear transformations that mandate these camera systems to be linear.
