we have carried out the research on adjacency effect since 2004 and conducted 2 satellite and 1 aerial synchronous experiments.The experiments on May 11st and July 25th

2005 and the results analysis were introduced in this paper.With improved measurement design and measurement device

data are analyzed by comparing the spectral curves from ground measurement

flat platform measurement and framed platform measurement

the results show that the improved measurement can prevent more scatter lights to come in the adjacent measurement system.Two adjacent effect analysis results show that if the two pixels have the same brightness there are mutual adjacent influence source and the influence strength is around 12.5%

if the two pixels do not have the same brightness

the influence strength toward weaker pixel

in other word the less brighter pixels get more adjacent effect.
