3 Description

The OPT8320 time-of-flight (ToF) sensor is part of the TI 3D ToF image sensor family. The device is a high-performance, highly-integrated, complete system-on-chip (SoC) for array depth sensing, consisting of a versatile timing generator (TG), an optimally designed analog-to-digital converter (ADC), a depth engine, and an illumination driver.

The programmability of the built-in TG offers the flexibility to optimize for various depth-sensing performance metrics [such as power, motion robustness, signal-to-noise ratio (SNR), and ambient cancellation]. The built-in depth engine computes the depth data from the digitized sensor data. In addition to the phase data, the depth engine provides auxiliary information consisting of amplitude, ambient, and flags for each pixel and the full-array statistical information in the form of a histogram.
