Multispectral linear array focal plane

A description is provided of a sensor chip array for a unified multispectral focal plane for the Multispectral Linear Array (MLA) instrument. The involved concept of sensing multispectral earth resources imagery through the use of spectral filters deposited directly on a single row of silicon charge-coupled device (CCD) chips has been considered for a number of years. A simplified focal plane was designed after a number of experiments. Technology considerations regarding the design of the multispectral focal plane are discussed. Experimental data are presented which show that the arising problems have been or can be solved.
