Amplification Technologies Corp. announced the availability of a new variant of its Discrete Amplification Photon Detector Negative-feedback Geiger mode avalanche photodiode for 3D LiDAR and other applications: a Fiberized-DAPD. ATC’s Fiberized-DAPD offers single-photon level detection ability, wide dynamic range, a large linearity range, and an extremely high repetition rate of up to 100MHz. In addition, the Fiberized-DAPD can operate in an always-on mode with fast response. The Fiberized-DAPD uses discrete amplification, which monolithically integrates a negative feedback circuit within the photodetector to create very high sensitivity. The Fiberized-DAPD provides several benefits in comparison to free-space optics configurations: Heat management, to cool the TEC and hence the DAPD; Ease of building signal processing electronics outside of the optical apparatus; and Optical isolation in LiDAR applications, so the laser pulse won’t trigger a response because of reflections from the LiDAR encapsulation. Key product features and their importance for real-time 3D imaging: 950nm to 1650nm wavelength range: These detectors operate in the eye-safe range (unlike the combination of a silicon detector and a GaAs laser).
