3 Description
The OPT8241 time-of-flight (ToF) sensor is part of
the TI 3D ToF image sensor family. The device
combines ToF sensing with an optimally-designed
analog-to-digital converter (ADC) and a versatile,
programmable timing generator (TG). The device
offers quarter video graphics array (QVGA 320 x 240)
resolution data at frame rates up to 150 frames per
second (600 readouts per second).
The built-in TG controls the reset, modulation,
readout, and digitization sequence. The
programmability of the TG offers flexibility to optimize
for various depth-sensing performance metrics (such
as power, motion robustness, signal-to-noise ratio,
and ambient cancellation).
