Small Form-factor Structured Light Pattern Generator Reference Design for Portable 3D Scanners

TIDA-080001

Design files

Overview

This 3D scanning reference design enables faster development of portable 3D scanner and machine vision applications using structured light triangulation technique where DLP® technology is used to project highly flexible patterns on an object. This design uses the DLP® Pico™ 0.2-inch TRP WVGA DMD (DLP2010) with the DLPC3470 display and light controller. The compact physical size of the DLP2010 is well-suited for portable equipment where small form factor and low power is important. This reference design comes with an example light engine design which includes electronics and optics along with software to generate different light pattern sets used in 3D scanning designs. The same electronics design can also be used with DLP2010NIR DMD which is useable for NIR light sources accommodating wavelengths ranging from 700 nm to 2500 nm. With high-speed and programmable patterns possible with DLP technology, designers can achieve high-speed 3D image reconstruction at micron-level resolution that is useful in a broad set of applications such as 3D cameras, facial recognition biometrics, 3D dental scanners, robotic vision and factory automation.

Features
  • Features DLPC3470 display and light controller and fully integrated DLPA2005 PMIC/LED driver
  • Electronics design supports both DLP2010 and DLP2010NIR – visible and NIR wavelength 
  • DLP2010, DLP2010NIR - 854 × 480 array of aluminum micrometer-sized mirrors in an orthogonal layout with flexible and precise light control
  • Used in DLP2010EVM-LC layout
  • Capability to display monochrome and RGB patterns with flexible triggers for camera control 
  • Includes a production-ready optical engine with programmable LED driver ( 0 to 650 mA)
  • PC software GUI to send any types of patterns to the light engine

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
