Introducing the AS-DT1: The Smallest and Lightest LiDAR Depth Sensor by Sony Electronics

Sony Electronics Unveils AS-DT1 LiDAR Depth Sensor

In a groundbreaking announcement, Sony Electronics Inc. has introduced the AS-DT1—dubbed the world's smallest and lightest LiDAR depth sensor. Measuring only 29mm x 29mm x 31mm and weighing just 50 grams, this remarkable device is designed for precision measurement applications where space and weight are critical.

What Makes the AS-DT1 Stand Out?

The AS-DT1 is more than just a compact sensor; it integrates advanced optical lens technology sourced from Sony's machine vision cameras. This innovative design enables its use in a variety of lightweight devices, including drones, robotics, and industrial applications. The sensor's miniaturization is a game-changer, making high-precision measurements accessible in a compact form factor that previously seemed unattainable.

Superior Measurement Capabilities

This miniature sensor utilizes 'Direct Time of Flight (dToF)' technology, enhancing accuracy with fast measurements and high distance resolution. It features a proprietary dToF ranging module equipped with a Single Photon Avalanche Diode (SPAD) sensor, which allows it to measure distances accurately in three dimensions: length, width, and depth.

One of the key advantages of the AS-DT1 is its ability to accurately gauge distances to low-contrast and low-reflectivity objects—situations where traditional methods often struggle. This makes it perfect for complex environments like retail stores, where the presence of various fixtures and individuals can be challenging.

High Precision and Long Measurement Range

The AS-DT1 provides accuracy for both indoor and outdoor applications. It can effectively measure distances at 10 meters with a margin of ±5 cm, which significantly enhances operational efficiency across various use cases. The range extends to an impressive 40 meters indoors and 20 meters outdoors, even under high ambient light conditions, making it ideal for inspecting infrastructure like bridges and highways.

Compact, Lightweight, and Durable Design

Built using a robust aluminum alloy, the AS-DT1 strikes an exceptional balance between lightweight design and durability. This attributes allows seamless integration into autonomous mobile robots and drones, both of which have strict limitations regarding size and weight to optimize performance.

The AS-DT1 is expected to be publicly showcased at the Xponential event in Houston, Texas, occurring from May 20 to 22, 2025, with availability anticipated in Spring 2026. Attendees can witness the prototype and learn firsthand about its transformative capabilities.

Why This Matters

As industries increasingly leverage automation and robotics, the demand for high-performance, compact sensors continues to rise. The AS-DT1 not only meets this demand but sets a new standard in LiDAR technology, offering solutions that will benefit a variety of sectors, including logistics, manufacturing, and even food service.
