LiDAR is a ranging technique that is increasingly being employed in applications such as mobile range finding, automotive ADAS (Advanced Driver Assistance Systems), gesture recognition and 3D mapping. Employing an SiPM as the photosensor has a number of advantages over alternative sensor technologies such as APD, PIN diode and PMT particularly for mobile and high volume products.

SensL SiPM’s have proven robust in other high volume markets such as medical imaging and now LiDAR applications can benefit from sensors designed to be industrial grade and delivered at the lowest cost possible.

A recent article on i-micronews discusses SensL sensors for LiDAR applications. More information on SiPM sensors for Automotive ADAS can be found here.

SiPM Benefits for Ranging

  • Single Photon detection at 905nm
  • Responsivity of 530kA/W at 905nm
  • Low power – lower operating voltages and simple readout electronics allow a low power design
  • High bandwidth and fast response time – minimize range measurement time
  • Low noise and high gain – good signal to noise ratio (SNR) is achievable
  • High dynamic range
  • Standard CMOS fabrication process – low cost, highly uniform and scalable production
  • Small size SMT packaging – 1mm sensors available
  • Ability to take advantage of low laser power direct ToF ranging techniques
