ADI Company Launches the First High Resolution Module for 3D Depth of Field Measurement and Vision System

     Analog Devices, Inc. (ADI) announced the launch of the first high-resolution, industrial quality, indirect time of flight (iToF) module for 3D depth measurement and vision systems. The new ADTF3175 module enables cameras and sensors to perceive 3D space with a resolution of 1 million pixels, and provides iToF technology with an accuracy of up to+/- 3mm, which can be used for machine vision applications such as industrial automation, logistics, medical health and augmented reality.

     ADTF3175 provides designers with an expandable, well designed and calibrated depth of field system that can be integrated into 3D detection and vision systems without the need to design special optics or solve electromechanical integration challenges, thus speeding up the time to market by simplifying the complex sensor design process. This reliable and durable high resolution module is designed for operation in various environmental settings. It uses Lumentum Operations LLC's advanced three junction vertical cavity surface emitting laser (VCSEL) technology and can be tested under various lighting conditions. Lumentum Operations LLC is a leading VCSEL array supplier of light detection and ranging (LiDAR) and 3D detection applications.

     T é a Williams, senior vice president and general manager of 3D testing at Lumentum, said: "We are pleased to cooperate with ADI to provide solutions for demanding and high-resolution 3D detection applications in the industry. Our scope of cooperation ranges from expanding reality to industrial applications such as robots, intelligent buildings and logistics systems. Our 10W VCSEL array helps ADI achieve more functional detection and vision systems, which can operate under various lighting conditions, so as to eliminate environmental barriers and achieve wider and more extensive Rapid machine vision deployment. "

     The ADTF3175 has an infrared illumination source with optics, laser diodes, and drivers, and a receiver path with lenses and optical band-pass filters. The module also contains flash memory for calibration and firmware storage, and a power regulator for generating local power supply voltages. A variety of operation modes are preset in the module, which are optimized for long distance and short distance.

     Tony Zarola, senior director of ToF of ADI, said: "Machine vision needs to achieve a leap, so that smaller and more subtle objects can be perceived faster in an industrial environment that is usually full of harsh conditions and multiple interferences. ADTF3175's excellent resolution and accuracy enable vision and detection systems (including industrial robots) It can better understand the space where it is located, and ultimately improve the production efficiency, so as to undertake the task requiring higher accuracy. The introduction of this module will help fill a large gap and accelerate the deployment of next-generation automation solutions and key logistics systems. "

     The ADTF3175 module will be attached with an open source reference design for the entire system, all necessary drivers, and the available ADI complex depth of field processing functions. ADI also provides guidance on how to obtain Class 1 eye safety certification for final products.
