Abstract

The invention discloses an InGaAs shortwave infrared detector signal processing system. The InGaAs shortwave infrared detector signal processing system comprises an InGaAs shortwave infrared detector, a signal input end, a differential single-end converting circuit, a signal modulating and filtering circuit, an analog-digital conversion circuit, and a data processing circuit. Through the differential single-end converting circuit, the system realizes the signal impedance matching, amplification, and supporting of main backup interfaces; through being treated by the signal modulating and filtering circuit, the signal enters the analog-digital conversion circuit and outputs digital-form data; finally, the data is transmitted to the data processing circuit. Compared with the traditional InGaAs shortwave infrared detector signal processing system, the InGaAs shortwave infrared detector signal processing system is low in circuit leading noise, main backup in an input end supporting system, strong in anti-jamming ability, and so on.
