Sony Electronics has introduced the AS-DT1, a state-of-the-art LiDAR depth sensor, designed to deliver high precision in compact devices. Measuring just 29mm on each side and weighing a mere 50 grams, this innovation is said to be the smallest and lightest sensor in its category. Leveraging Sony’s expertise in miniaturization, the sensor aims to redefine depth measurement capabilities in space-constrained applications.

The AS-DT1 utilizes Direct Time of Flight (dToF) technology, which calculates distance by measuring the time it takes light to travel to an object and reflect to the sensor. At the heart of the device is a Single Photon Avalanche Diode (SPAD) sensor, enabling it to gather distance data across multiple points with high accuracy. This allows the sensor to measure objects in three dimensions, length, width, and depth, even in scenarios with low contrast or low-light conditions. It is also designed to perform effectively both indoors and outdoors, with a range of up to 40 meters indoors and 20 meters in bright external conditions.
Who is this for? The AS-DT1 targets industries requiring precise spatial data in compact setups. This includes robotics, where autonomous mobile robots use sensors to navigate warehouses or industrial facilities safely. Its lightweight and robust aluminum housing makes it ideal for drones, which benefit from reduced weight and extended flight durations. Other potential users include retailers and event organizers, as the sensor can help track customer flow or object placement in dynamic indoor environments.
What could that be used for?
The AS-DT1 addresses the challenge of accurately measuring hard-to-detect surfaces, such as low-reflectivity objects, where traditional sensors might fail. By making these measurements reliable, it could enable significant advancements in robotics, logistics, infrastructure inspection, and automation. For instance, in warehouse automation, the sensor’s ability to calculate precise distances could improve collision avoidance systems, enhancing safety and efficiency. Additionally, its capacity to operate under adverse conditions, such as bright sunlight, solves issues faced by drones during outdoor inspections.

Set to enter the market in spring 2026, the sensor could represent a significant technological shift in several fields that rely on precise depth sensing. Its potential to streamline operations, reduce risk, and expand the range of feasible automation applications aligns with broader trends toward intelligent systems and robotics innovation. A prototype will debut at the Xponential trade show in Houston this May, offering a glimpse at the future of compact LiDAR technology. Whether inspecting infrastructure or navigating bustling storefronts, the AS-DT1 is designed to enhance precision and unlock new possibilities in technology-driven environments.
