Solid-State LiDAR Technology 2026 — PatSnap Eureka
Solid-State LiDAR Technology Landscape 2026
70+ patent records analysed across VCSEL/SPAD flash, MEMS, FMCW, and optical phased array architectures. Understand who holds the IP, where filings are concentrated, and which frontier directions are emerging in solid-state LiDAR for autonomous vehicles, robotics, and intelligent infrastructure.
Five Dominant Solid-State LiDAR Architectures
The dataset spans five distinct technical sub-domains, each with different maturity levels, IP concentration, and applicability to automotive, UAV, and infrastructure use cases. According to WIPO patent classification data, photonic sensing is among the fastest-growing technology areas globally.
Flash LiDAR with VCSEL Arrays & SPAD Detectors
Flash LiDAR illuminates an entire scene simultaneously using a dense VCSEL emitter array and captures returns via a SPAD or APD focal-plane detector array. This approach eliminates beam steering entirely but requires careful management of eye safety, ambient noise, and array uniformity. Opsys Tech and Huawei hold representative filings in this cluster, including Huawei's 2024 PCT filing on tunable-aperture SPAD receivers that adapt dynamically to ambient noise levels.
Eye-safe long-range operationMEMS Mirror & Hybrid Electro-Optical Beam Steering
Semi-solid-state systems use MEMS oscillating mirrors for one or both scan axes, retaining micro-scale moving parts. Dual MEMS configurations achieve full 2D scan coverage while maintaining compact form factors. Infineon Technologies and Intel hold key filings, including Intel's 2023 synchronized dual-MEMS approach where one mirror steers outbound beams and a second collects return light over the same angular range.
Infineon + Intel key filersActuator-Assisted Distributed Solid-State Arrays
Rather than macro-rotation, this approach uses small linear actuators to dither relative positions of the laser array and collimating optics, shifting FOV coverage at fine angular increments. The distributed modular architecture places multiple independent transmitter modules around a vehicle perimeter. Opsys Tech's 2022 filing describes actuator coupling causing sub-mm lateral displacement to scan FOV without full mechanical rotation.
Sub-mm actuator displacementFMCW Coherent Detection Architectures
FMCW LiDAR uses frequency-chirped laser sources and coherent optical mixing to extract both range and instantaneous radial velocity from a single measurement. These systems offer inherent immunity to pulsed interference and ambient light. Northrop Grumman's 2024 filing describes a spiral phase plate resonator that steers an FMCW beam over a full 360° FOV by tuning laser frequency, with no mechanical scan required.

Top Assignee Patent Record Counts
Opsys Tech leads with 20+ records — more than double the next highest assignee — indicating strong portfolio concentration in distributed flash and actuator-scan SS-LiDAR.
Innovation Maturity Phases (Filing Activity)
Dense filing activity concentrated between 2019 and 2026, reflecting the field's transition from research prototypes toward production-ready automotive-grade systems.
Where Solid-State LiDAR IP Is Being Filed
Among retrieved results, CN leads in record count with approximately 30 records, followed by JP (approximately 25 records), KR (approximately 10 records), and EP (approximately 5 records). China's dominance reflects both domestic filers — Hesai, Robosense, Huawei — and major foreign assignees such as Opsys Tech and Infineon filing aggressively in CN. Japan is notably active as a PCT national phase jurisdiction, hosting filings from Opsys Tech, Velodyne, Innoviz, and Northrop Grumman.
Opsys Tech Ltd. is the single highest-volume assignee with at least 20 distinct records across KR, JP, CN, and EP jurisdictions. This covers Flash, actuator-scan, distributed modular, multi-wavelength, and noise-adaptive architectures — the most concentrated IP portfolio in the dataset. Innoviz Technologies Ltd. (Israel) accounts for at least 8 records, all focused on adaptive light-flux scanning, signalling deep specialisation. According to EPO filings data, photonics and sensing are among the fastest-growing patent technology areas in Europe.
Notable Chinese domestic filers include Hesai Technology (Shanghai) filing dual-FOV solid-state LiDAR architectures in CN (2025), and Suteng Innovation Technology (Robosense America) with VCSEL/SPAD co-integration. Huawei Technologies contributes a PCT filing on SPAD-based LiDAR with adaptive aperture control (2024, WO). This signals China's transition from technology consumer to technology originator in LiDAR — a dynamic tracked by PatSnap's IP analytics platform across multiple high-tech sectors.
Innovation is not evenly distributed: in this dataset, Opsys Tech alone accounts for a disproportionate share of records, suggesting strong patent portfolio concentration in the distributed flash/actuator-assisted SS-LiDAR segment. R&D teams entering this space should conduct freedom-to-operate analysis with particular attention to FOV-overlap-based selective detector activation and actuator-dithered scan claims.
Emerging Directions in Solid-State LiDAR (2024–2026)
Among records dated 2024–2026 in this dataset, six frontier directions are apparent — from multi-wavelength resolution improvement to photonic chip-scale integration.
Multi-Wavelength Point Cloud Generation
Opsys Tech's 2026 EP filing and its KR counterpart use interlaced beam profiles at two wavelengths to sub-divide angular resolution beyond what a single wavelength source can achieve — a software-optics co-design approach to resolution improvement without denser arrays.
Metasurface & Flat Optics Integration
Robosense America's 2025 CN filing integrates metasurface-based optical elements into the beam steering, emission, and collection path — enabling thinner, lighter, and potentially lower-cost optics than conventional refractive elements.
Real-Time Performance Degradation Detection
Innoviz Technologies' 2026 CN filing applies statistical analysis across multiple scan cycles to identify volumetric scattering targets indicating environmental conditions (rain, fog, dust) and trigger system-level alerts — a functional safety layer built into the LiDAR processing pipeline.
Dual FOV / Dual-Range Tiered Architectures
Hesai Technology's 2025 CN filings describe solid-state LiDAR with two distinct transmitter subsystems — one covering wide FOV at moderate range, a second covering narrower FOV at longer range — sharing a single receiver, allowing independent optimization without cost-scaling linearly with each capability.
Where Solid-State LiDAR Is Being Deployed
The dataset spans five major application categories. Automotive ADAS dominates, but UAV, infrastructure, industrial, and multi-sensor fusion applications are each represented by distinct patent clusters. The NHTSA has identified LiDAR sensing as a critical enabling technology for Level 3+ autonomous driving safety standards.

Solid-State LiDAR Technology — key questions answered
Solid-state LiDAR systems eliminate macro-mechanical rotation by integrating beam steering, light emission, and photodetection into compact semiconductor modules. Unlike traditional rotating LiDAR assemblies, SS-LiDAR uses semiconductor-based, MEMS, or fully integrated optical components to achieve greater reliability, reduced form factor, and lower long-run cost.
