Peak holding circuit of laser pulse signal

The utility model discloses a peak holding circuit of laser pulse signal, including transimpedance amplifier D, the pressure differential of transimpedance amplifier D between to voltage pulse signal vin and output voltage vout enlargies, and the current conveyance diode Z of transimpedance amplifier D output charges to holding capacitor C4. The utility model discloses a peak holding circuit that the discrete component was realized, add the peak holding circuit in the voltage pulse signal treatment circuit, advance the line broadening to the voltage pulse signal peak value, the regulator circuit parameter, make wide delay to the tens of us of exhibition, it samples to send into the AD converter, can make and realize continuous sampling several point in the cycle at a laser pulse, the rethread treater carries out average filtering algorithm processing to the data that the sampling obtained, the stability that can make the seeker measure target azimuth or every single move angle obtains very big improvement wit
