Abstract
The EOS/MISR instrument contains nine cameras; each camera focal plane consists of four closely spaced, linear CCD arrays. Each of the four arrays is preceded by a narrow bandpass filter covering a distinct spectral region. Testing of two engineering model cameras revealed spatial and spectral optical crosstalk levels not predicted by stray light analysis. A detailed investigation of filter coating anomalies and the filter assembly/CCD geometry elucidated several mechanisms responsible for optical crosstalk. These mechanisms, as well as recommendations concerning the design of future focal planes, are presented in this paper.
