New 3D Scanning Features

TI DLP® technology offers a wide portfolio of high speed chips for 3D scanning applications, including intra-oral scanning, automated optical inspection (AOI) and solder paste inspection (SPI). All of these scanning applications require programmable structured light patterns. New features were introduced in the 9.x.x version of the controller firmware that adds multi-bit monochrome internal pattern display support and allows the choice to start the pattern set at a non-zero start entry index.

Multi-bit Monochrome Pattern

Internal pattern streaming mode displays 1D pattern data stored in flash. The new firmware enables 4, 5, and 6-bit depth monochrome pattern projection in internal pattern streaming mode. This pattern creates two advantages:

  1. Enables multi-bit pattern displays with higher pattern rates.
  2. Allows storing higher number of patterns within a pattern set.

Non-Zero Start Entry Index

User can now configure the start of pattern set with a non-zero index. This feature helps in displaying the same pattern set content with different colors without having the overhead of fetching the pattern data from memory.
