InGaAs image sensors InGaAs linear image sensors InGaAs linear image sensors are comprised of an InGaAs photodiode array with high sensitivity in the near infrared region, charge amplifier arrays, an offset compensation circuit, a shift register, and a timing generator. The signal from each pixel is read out in charge integration mode. The Gl 1135/G11620 series use a back- illuminated structure to allow signal readout from a single video line. f Short-wavelength enhanced type range from the visible to near infrared region (0.5 to 1.7 um). (Typ. Ta=25 °c, unless otherwise noted)
