ADTF3175 from Analog devices is the industry’s first high-resolution module for 3D Depth sensing applications. The  ADTF3175 uses indirect Time-of-Flight (iToF) tech module for 3D depth sensing and vision systems. The ADTF3175 features an infrared light source with optics, laser diode and driver, and a receiver path with a lens and an optical band-pass filter that makes integrating the module into a product cheaper and faster. It offers high accuracy of +/-3mm and is intended for a wide variety of applications ranging from healthcare, industrial automation, logistics, augmented reality, etc.

The ADTF3175 enables cameras and sensors to perceive 3D space in one megapixel resolution. It offers designers a scalable, fully engineered, and calibrated depth system that can be integrated into 3D sensing and vision systems, eliminating the need to design specialized optics or address electromechanical integration challenges. This in turn speeds time to market by simplifying the complex sensor design process.

The module features a robust design which is suitable for use in outdoor environments. Moreover, to enable sensing in a wide range of lighting conditions it employs Lumentum Operation’s triple junction vertical-cavity surface-emitting laser (VCSEL) technology for light detection and ranging (LiDAR) and 3D sensing applications.

“We are thrilled to work with ADI on solutions for the industry’s most demanding and highest resolution 3D sensing applications, ranging from extended reality to industrial applications like robotics, intelligent buildings, and logistics systems,” said Téa Williams, Senior Vice President and General Manager of 3D Sensing at Lumentum. “Our 10W VCSEL arrays allow ADI to enable more capable sensing and vision systems that can operate under a wide range of lighting conditions and thereby removing environmental obstacles to broader and more rapid machine vision deployment.”

The ADTF3175 features a flash memory for calibration and firmware storage plus power regulators to generate local supply voltages. It comes pre-programmed with several operating modes that are optimized for long and short range. The company plans to release open-source reference design for the module, it will also include all of the required drivers and access to ADI’s sophisticated depth processing capabilities. Which will simplify integration of the module to any system.
