Project: Advancing time-of-flight technology for high performance light detection and ranging

Acronym LIANDRI (Reference Number: PS-2016_12)
Duration 01/04/2018 - 30/03/2021
Project Topic Sensor technology plays a vital role in a wide range of applications, spanning from daily live appliances and sophisticated industrial environments to mission critical infrastructures. Photonics is known for enabling leaps in performance past that found in the state-of-the-art. A prominent example is time-of-flight imaging: By illuminating targets with light and acquiring the reflection thereof, a highly detailed 2D representation of the scene as well as depth information can be obtained. This is highly attractive for 3D sensor applications concerning object localisation, tracking and identification such as required for automated manufacturing or self-driving automobiles. Purely electronicsaided solutions such as ultra-sonic detection or RADAR technology experience flaws since either range or resolution cannot be achieved. Besides, state-of-play cameras lack reliability under certain conditions such as frontlighting. All these flaws of conventional sensors leave room for misinterpretation in an environment where ultra-high reliability is paramount. LIANDRI aims at novel component technology for photonic sensing relying on light-based detection and ranging (LIDAR) with high precision and sensitivity. Time-of-flight photodetection enabled by CMOS- integrated 2D single-photon avalanche photodiodes in combination with GaN high-power optoelectronics for short-pulsed light generation in the GHz range will comprise the key elements for cost-effective direct image acquisition for long ranges of up to 250m at high precision and reliability. Developed sensor test-chips will be evaluated under realistic environments for the representative applications of automotive LIDAR and object tracking in confined manufacturing environments. The presence of innovative industrials along the value chain, in particular by AMS as component vendor of optoelectronics and Soft2Tec as system developer for 3D cameras, will ensure exploitable technology for later commercialisation.
