# Deptrum

> Deptrum (光鉴科技) is a Chinese 3D vision company founded in 2018 by three Silicon Valley scientists, including a former Apple depth-hardware lead. It builds full-stack 3D depth-sensing solutions - nanophotonic chips, structured-light and Time-of-Flight cameras, and AI perception algorithms - that let machines see and measure the physical world. Its hardware powers robots, smart cockpits, palm-payment terminals, smartphones and new-retail systems across finance, automotive and IoT.

- **Founded:** 2018
- **Headquarters:** Shanghai, China (offices in Shanghai and Shenzhen)
- **Founders:** Li Zhu (Founder & CEO - Ph.D. EE, UC Berkeley; B.S. EE, Tsinghua; former depth-hardware lead at Apple; Forbes China 30 Under 30 (2018)), Bo Wang (Co-founder & CTO - Ph.D. EE, Stanford University), Fanglu Lu (Co-founder & Chief Scientist - Ph.D. EE, UC Berkeley)
- **Team size:** 100+ core R&D members (Apollo-listed headcount of ~14 reflects a single office/record, not total)
- **Products:** Wavefront Processor (WFP) / Nanophotonic Chip, Aurora Structured-Light Depth Camera series, Stellar ToF Depth Camera series, Nebula sToF Depth Camera series, HandPass Dual-Mode Palm Recognition Camera
- **Notable:** Developed the world's first non-VCSEL structured-light depth solution, 1,000+ patent applications filed, 50+ industry honors and awards

## Products & services

- **Wavefront Processor (WFP) / Nanophotonic Chip** — Core nanophotonic technology that shapes and processes light at the chip level, enabling the world's first non-VCSEL structured-light depth solution.
- **Aurora Structured-Light Depth Camera series** — High-precision structured-light 3D cameras (e.g. Aurora 900/910/930) for robot obstacle avoidance, volume measurement and industrial sensing, operating across wide illumination ranges.
- **Stellar ToF Depth Camera series** — Time-of-Flight depth cameras (e.g. Stellar 400/420/800) with on-board ARM processing for robots, smart homes and security.
- **Nebula sToF Depth Camera series** — Structured-ToF fusion cameras (e.g. Nebula 400/240) combining near-distance ultra-high precision with far-distance depth sensing.
- **HandPass Dual-Mode Palm Recognition Camera** — Palm-vein and palm-print biometric camera for contactless payment and access control, with anti-spoofing depth verification.
- **Under-Screen 3D Camera Solution** — A 3D structured-light face-recognition module that sits beneath a smartphone display for invisible secure face unlock.
