3D time-of-flight (ToF) sensors provide fast, 3D vision systems for machine vision, robots, building-automation systems, and augmented-reality systems. Along those lines, Analog Devices packed its 3D ToF platform into a compact module, the ADTF3175 (Fig. 1).

1. The evaluation platform contains a ADTF3175 module 3D time-of-flight sensor.

In the video, Erik Barnes shows off the power-efficient, 1-Mpixel, 3D TOF sensor in the company's eval module. The module is built into a custom, handheld capture system.

The ADTF3175 chip has 1k × 1k resolution with a 75-degree field of view (Fig. 2). The imager lens integrates a 940-nm bandpass filter. It has a 4-lane, 1-Gb/s MIPI CSI-2 interface and 2-/4-wire SPI interface. Depth range spans from 0.4 to 4 m with a depth accuracy of 3 mm.

I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.

I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
