A NASA laboratory for evaluating linear detector arrays for remote sensing applications from the visible to shortwave infrared is described. Nominal requirements for acceptable sensor performance are presented for the critical parameters of signal-to-noise ratio, modulation transfer function, response linearity, dynamic range, and detector-to-detector response uniformity. Results of tests are presented for a custom-developed multispectral linear array from RCA and two commercial arrays from Texas Instruments and Reticon for the visible and near infrared. The custom array was clearly superior to its off-the-shelf counterparts in signal-to-noise ratio and dynamic range. All the arrays were found to have somewhat less than desirable modulation transfer functions but excellent response linearity.
