SC486 - Optoelectronic Devices for LIDAR and High-BW or 3D Sensing New

Monday, 09 March
09:00 - 12:00

Short Course Level:


 Martin Zirngibl, Krzysztof Szczerba, Anna Tatarczak; Finisar, USA

Short Course Description:

The course will cover application of opto-electronic devices commonly used in optical communications in LIDAR and 3D sensing. A technical introduction to the 3D sensing and lidar technologies will be provided, including:

  • structured light and time of flight camera systems,
  • direct detection and coherent LIDAR systems.

The introduction will cover the underlying principles and high-level system requirements. Applications of these technologies, as well as their strengths and weaknesses will be presented. The introduction will be followed by a discussion of the optoelectronic components used in both transmitters and receivers. Receiver technologies for 3D sensing and LIDAR systems, such as CMOS or SPAD arrays, APDs, and SPADs will be presented and compared. Additionally, an overview of beam scanning methods For LIDAR systems will be presented. The core of the content on optoelectronic devices will focus on Vertical Cavity Surface Emitting Lasers (VCSELs), which are nearly universally the only type of an illuminator used in 3D sensing systems, both based on structured light and time of flight. The VCSEL focused part of the course will cover:

  • defining requirements and specifications,
  • characterization methods of the components,
  • electrical and thermal system integration and best practices,
  • model driven system design.

The section on VCSELs and their practical application in 3D sensing systems should provide the course participants with an understanding of design and performance trade-off.

Short Course Benefits:

The course is intended to provide the audience with basic understanding of 3D sensing and LIDAR systems and application of active optoelectronic components in these systems.

Learn to properly choose and specify components for 3D sensing and LIDAR systems.

Learn modeling approaches in system design for illuminators for 3D Time of Flight cameras.

Learn to identify integration challenges and best practices.

Short Course Audience:

The course is intended for everyone working with 3D sensing and LIDAR systems at all stages of development and production: research, design, engineering, test, specification, purchasing, marketing and management. Experts in optoelectronic devices as also welcome, as they can learn about the application side of the components. General background and professional experience in electronics and photonics is recommended.
