3 Hamamatsu s Market Involvement LiDAR System Design Photodetectors Light Emitters Beam Steering (MEMs Mirrors) - Si and InGaAs photodiodes, APD, SiPM, distance image sensors - For 905 & 1550nm systems - Edge emitter laser diodes (CW/Pulsed) - For 905nm systems - Electromagnetic based MEMs Mirror (1D or 2D) - For 905 & 1550nm systems Global leader in photonic components for various industries, >$1 billion revenue Currently in discussion with majority of Tier I/OEM & LiDAR designers 3

4 Autonomous and ADAS Overview (Today) Limited Automation Level 0 Level 1 Level 2 No automation Driver has complete control Driver assistance Default level of automation for most new cars today Limited automation Limited availability on some new vehicles today Ultrasonic Radar LiDAR Camera 4

5 Autonomous and ADAS Overview (Future) Technologies Still Being Developed (Semi to Full Automation) Level 3 Level 4 Level 5 Conditional automation Driver is expected to intervene and take over the control at any time High automation Driver can take over the control but not required Full automation No driver interaction necessary Sensor Fusion Functional Safety Ultrasonic Sensors Camera GPS 3D Sensors Radar LiDAR 5
