InGaAs linear array focal plane sensor

The GD-NIR512L2-CD shortwave infrared InGaAs linear array sensor has the characteristics of high sensitivity, low noise, and low dark current. The sensor is composed of InGaAs photodiode array chips and CMOS signal processing circuit chips. It is conductive connected through indium (In) convex dot arrays and can be widely used in fields such as agricultural product detection, industrial detection, and optoelectronic detection.
The sensor is composed of two independent 1X512 structured circuits, each containing 512 rubber channels. Each channel contains a charge amplification circuit, a CDS gain circuit, a hold circuit, a column buffer circuit, and a control circuit logic. The input stage adopts a CTIA structure with multiple levels of charge voltage conversion gain, supports anti corona and correlated dual adoption (CDS) noise reduction functions, and supports two forms of cooling and non cooling.
