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.
