Orion Pattern Projectors
Meet the world’s highest performing, most compact family of pattern projectors that improve every aspect of 3D depth sensing for smartphones, robots, AR/VR and the IoT.
Create virtually any dot, line, or flood pattern with an ultra-wide, >150º field of illumination.
Orion pattern projectors are designed to convert the photons emitted from an array of laser emitters (VCSEL) into a high contrast dot or line pattern. Achieving these patterns in a single, flat meta-optic allows them to be easily integrated into a variety of 3D sensing platforms that can meet the requirements of mobile, IoT or robotics applications, both for time of flight and structured light applications.
The Starlight projector consists of a new, wide field pseudorandom dot pattern meta-optic from Metalenz (“Orion 18K”) paired with a pseudorandom VCSEL from Vertilite (“Dolphin”). The Starlight projector is the most compact, high performance, low cost structured light solution available for 3D sensing systems, catering to a range of applications including face authentication for smartphones, contactless access control, security, gesture recognition, obstacle avoidance, and automotive in-cabin monitoring. Generating ~18,000 dots in a pseudorandom pattern at 940nm, Starlight uses the Orion 18k meta-optic to collimate and diffract the light coming from 391 VCSEL emitters arranged in a pseudorandom array. The Orion 18k meta-optic dot pattern provides class leading power per dot with high contrast, making it suitable for use under any indoor/outdoor lighting conditions.
Combine the function of five optical elements into one meta-optic.
Orion pattern projectors consist of a single meta-optic paired with a VCSEL, wheras traditional sensors require at a minimum two and more typically 4 or 5 optical elements mounted in a lens barrel on top of the VCSEL.
Advantages of Orion Pattern Projectors
Next-generation Smartlock and Payment Kiosk systems from Dilusense leverage an Orion meta-optic dot projector from Metalenz, which enables improved structured light pattern to enhance the biometric recognition performance of Dilusense’s 3D sensing systems.
