Mirrorcle Technologies will present its latest developments in automotive laser projection systems at this year’s SPIE Photonics West exhibition in San Francisco. The company’s CEO, Dr Veljko Milanović, and senior electronics engineer, Abhishek Kasturi, will provide an overview of some of the company’s most recent R&D achievements at the MOEMS and Miniaturized Systems XVIII conference (Session 5, Paper 10931-21) titled “MEMS Mirror Module for Programmable Light System.” On Sunday morning, 3 February 2019 at 8:40 am, conference attendees will get an overview of the company’s programmable light system, enabled by the MEMS mirror module and the vector graphics laser projection (VGLP) architecture. This technology is tailored to industry demand for a high-contrast, high-brightness laser projection system for various display applications. Mirrorcle Technologies is also sponsoring the MOEMS conference Best Paper Award and will exhibit at booth number 4221 in the North Hall of the Moscone Center.
The vector graphics laser projection (VGLP) architecture
The paper, co-authored by Abhishek Kasturi, Veljko Milanović, Frank Hu, Hongjoo Kim, Derek Ho and Daniel Lovell (all from Mirrorcle Technologies in the US), is the result of customer-inspired research to address the need for automotive qualifiable, low-cost, compact and high visibility laser projection systems for use in automotive applications.
The team explored multiple technologies and investigated numerous approaches to laser-based projectors that could work in outdoor environments and compete with ambient light, while meeting compactness, cost, and efficiency. The result of the investigation and numerous outdoor tests was that the company’s own vector graphics laser projection (VGLP) architecture meets the demand effectively. Namely, the VGLP approach takes advantage of Mirrorcle’s high-bandwidth MEMS mirrors to create their contrast laser projection system.
The MEMS mirror module for lidar and lighting
In modest to high-power laser beam steering applications such as lidar and lighting, eye safety is paramount and depends on the beam-steering component (mirror) continuously moving and correctly responding to controller commands. The team designed the MEMS mirror module (MMM), which is designed around Mirrorcle’s fast beam steering MEMS mirror and a smart MEMS driver with real-time position and temperature monitoring. The MMM is designed to facilitate safety and increase the beam-steering bandwidth in lidar and lighting systems. It is designed to seamlessly replace the solution that lidar customers use today, which is the gimbal-less dual-axis MEMS mirror with the standard, open-loop MEMS driver.
Playzer and lidar on display
As in previous years, Mirrorcle Technologies will exhibit at booth number 4221 in the North Hall of the Moscone Center, where visitors will encounter bright, interactive demos of the technology discussed in the paper. Additionally, a Playzer, a pocket-sized programmable vector graphic laser projector, will be showcased and a number of these Playzers will be run from laptops and tablets for visitors to interact with and create their own laser displays. Newly announced by Mirrorcle for this SPIE exhibition is the RGB Playzer which adds a dimension of color to the VGLP display offering. A programmable light system (PLS) and the company’s scanning mirror system (SMS-2D), a complete beam-steering (transmitter) solution for modern MEMS-based solid-state lidar systems will also be demonstrated.
