【文字介绍】

"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).
Official evaluation module for the second-generation 3D Time-of-Flight (3D ToF) sensor from Texas Instruments. The Camera Development Kit (CDK) showcases the high-performance QVGA (320 x 240) resolution 3D ToF OPT8241 with its companion ToF controller OPT9221.

The OPT8241 CDK provides the three-dimensional location of each pixel, enabling accurate depth maps for 3D dimensioning, robotic navigation, 3D gesturing, and building automation. The CDK is highly configurable and allows the user to customize the performance of the solution to a given application.
