IMAGE SENSOR
InGaAs linear image sensor
G9494-256D/-512D
Near infrared image sensor (0.9 to 1.7 碌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.
