| IMAGE SENSOR InGaAs linear image sensor G9494-256D/-512D Near infrared image sensor (0.9 to 1.7 m) with high-speed data rate HAMAMATSU provides high-speed, near infrared image sensors designed for detectors used in on-line foreign object inspection equipment. These image sensors use square-shaped pixels that are ideally suited for software processing in pattern recognition systems. The signal processing circuit employs CTIA (Capacitive Transfer Impedance Amplifier) method to perform simultaneous charge integration on all pixels, so there is no time lag among the pixel output signals. Features Applications G9494-256D: 50 x 50 m G9494-512D: 25 x 25 m l CMOS readout circuit incorporated l Low dark current l Room temperature operation s S e le c t io n g u id e Typ e N o .
