Product Pickup Sensor Module Analog Devices

Many people looking for a ToF sensor probably have the following reasons: "I feel that the resolution and accuracy of conventional sensors are not enough," or "I want a sensor that is easy to incorporate into my company's applications in order to minimize the design work."

Here we introduce the ADTF3175, a high-precision ToF sensor module from Analog Devices that boasts a high resolution of 1 megapixel and can be directly embedded in a variety of devices. Improve the performance of your applications with this high-performance, versatile ToF sensor module.

Issues with conventional ToF sensors

ToF sensors, which measure the distance to an object, are used for a variety of functions, including SLAM (self-localization and mapping), collision avoidance, gesture control, and 3D scanning. Conventional ToF sensors are used in consumer products such as smartphones and game consoles, and have encountered the following challenges when developing applications that place importance on accuracy and performance:

Lack of resolution and precision makes it difficult to accurately measure small objects
The detection range is narrow, so multiple sensors must be installed.
The accuracy of image processing AI cannot be improved due to the low resolution of the data
When designing optical components from the chip, there are many things to consider and it takes time and effort.

In particular, applications that demand high reliability, such as industrial machinery, robots, and security systems, require ToF sensors with higher accuracy and resolution.

So, I would like to introduce you to Analog Devices' ToF sensor module "ADTF3175". With the industry's highest class resolution and high depth accuracy, it can be used in a wide range of applications, including industrial applications. Because it is a module type, it is easy to incorporate and realizes design efficiency. Let's introduce its features.

In terms of performance, it has three main features.

High resolution 1 megapixel

It achieves a groundbreaking high resolution of 1 megapixel (1024 x 1024). Since it can acquire high-definition data, it is possible to capture the shape, size, and movement of an object more accurately. This expands the range of processing that can be realized, and enables the consideration of high-performance systems that were difficult to achieve with conventional ToF sensors.

High depth accuracy over the entire depth range of ±5mm

It supports a depth range of 0.4 to 4m, with a depth accuracy of just ±5mm, which is highly accurate. It can clearly detect objects up to 4m away. It can perform stable measurements under various distance conditions. It also has the advantage of being easy to design, as the accuracy is consistent across the entire depth range.

Wide viewing angle of 75° x 75°

The sensor achieves an advanced wide viewing angle of 75 ° × 75 °. The wide detection range allows applications that require monitoring of a wide area to be handled with fewer sensors. This simplifies the design and reduces sensor costs.

Examples of features that can be explored with the ADTF3175

The ADTF3175 can be used to improve the performance of a variety of applications, including:

Precise gesture control: Recognizes even the movements of your fingertips for fine-grained control
High-precision 3D scanning: Scanning complex shapes such as boxes placed at an angle or cylindrical objects is now possible
Precise robot arm operation: Accurate recognition of small parts and randomly placed parts, improving the precision of the arm
Accurate picking control: Identify similar shapes to improve the accuracy of the picking device

Precise robot arm operation with ToF camera

High-precision 3D scanning with ToF camera

Ready-to-install sensor module

Another feature of the ADTF3175 is its ease of integration into applications. The ADTF3175 is provided as a sensor module and can be implemented in applications as is. Optical components such as imager lenses and laser diodes are integrated and calibrated for multiple resolution modes. Accurate data can be obtained simply by connecting the terminals, which simplifies component selection and optical design and significantly shortens development time.

In addition, an evaluation kit is provided, and you can try out the performance immediately by simply connecting it to a PC via USB. You can quickly evaluate data and operation without spending time on setup. An SDK is also available, and the necessary documents and codes are published on GitHub. By utilizing these tools, you can develop efficiently.
