In the era of Industry 4.0, intelligence, automation, and efficiency have become the core drivers of manufacturing development. As a critical component of industrial automation systems, the performance and reliability of sensors directly impact overall production efficiency and quality. In recent years, LiDAR sensors have gained widespread adoption in industrial applications due to their high precision, long-range detection, and strong environmental adaptability.

This article focuses on the AS5000 Series fully solid-state array DTOF LiDAR launched by Meiji Sensing, exploring its technological advancements and application prospects in the Industry 4.0 landscape.

I. Evolution and Current State of LiDAR Technology

LiDAR (Light Detection and Ranging) is a technology that uses laser beams to measure distance and detect objects. Since its introduction in the 1960s, LiDAR technology has evolved from mechanical systems to semi-solid-state and ultimately to fully solid-state designs.

• Mechanical LiDAR relies on internal rotating components for scanning. While offering high precision and resolution, it is complex, costly, and less reliable due to mechanical wear.
• Semi-Solid-State LiDAR reduces mechanical parts, enhancing stability and durability, yet still retains some moving components.
• Fully Solid-State LiDAR marks a significant breakthrough, eliminating all mechanical components and adopting electronic scanning technology. This not only enhances scanning speed and accuracy but also significantly reduces costs, making it highly competitive for industrial applications

II. Key Features of AS5000 Series Fully Solid-State Array DTOF LiDAR

The AS5000 Series represents the latest advancements in fully solid-state array DTOF (Direct Time-of-Flight) LiDAR technology. It is based on SPAD (Single-Photon Avalanche Diode) array DTOF combined with FLASH laser technology, enabling direct 3D point cloud data output with detailed object features.

1. Motion-Free Design

One of the most significant innovations of the AS5000 Series is the complete elimination of internal moving parts. Traditional mechanical LiDAR systems are prone to wear and failure due to rotating components, leading to reduced accuracy and downtime. By adopting a fully solid-state design, the AS5000 Series eliminates these reliability concerns, significantly enhancing stability and operational lifespan.
