　Key Features and benefits:

1. Fast, programmable image mode rate

(1) Real-time acquisition of 3D scanned data of moving objects

(2) Optimize scanning speed and accuracy of multiple objects and environments using adaptive pattern sets

2. Digital switching using a reliable MEMS reflective micro-mirror

Effectively suppresses the system's sensitivity to color, distance, motion and environment, thereby improving system performance without the influence of time and temperature

　　main reference devices;

1.dlp4500nir: Digital micro-mirror device (DMD)

The Dlp4500nir digital micro-mirror Device (DMD) can be used as a spatial light modulator (SLM) to quickly, accurately and efficiently manipulate near-infrared (NIR) light to produce the desired pattern. Due to its high resolution characteristics in a compact package size, Dlp4500nir DMD is often combined with a single unit detector to replace the expensive INGAA array detector design for a high performance, cost-effective portable solution.

The key point of this device is that up to 3 high-resolution video and Imaging Coprocessors (HDVICP2). Each coprocessor is capable of performing a single 1080p60-h encoding or decoding, or multiple encoding and decoding of a lower resolution or frame rate. In addition, multi-channel HD to HD or HD to SD code conversion and multi-encoding can also be done. With the ability to simultaneously process 1080P60 data streams, the tms320dm816x device becomes a powerful solution for today's demanding HD video applications.
