DLP2000: Using smallest TI DMD for structured light applications

Part Number: DLP2000
Other Parts Discussed in Thread: DLP2010, , DLPC3430

Hello

I'm a BSc student working on a paper regarding in-situ structured light applications for 3D reconstruction.

when i browse through all documents (found so far), i cannot find an answer to the question,
why are the smallest DMD that TI has in their product portfolio not mentioned in conjunction with
structured light applications e.g. www.ti.com/.../dlpt021c

are there technical limitations?
is it due to the low resolution?
are the lenses of the available optical engines just too distorted?
illumination issues?
lifetime expectations?
max frequency?
or is it just marketing?
why are the larger DMD's better suited? even diamond pixel orient.

has anyone experience e.g. already tried to create the stripes for 3D scanning with a
DLP2000/DLP2010 device? if so, is phase shift possible too?

would be glad to step into a rapid proto using one of the evm's available.

thanks in advance for your answers

Andy

  • Andreas,

    Welcome to the E2E forums, and thanks for your interest in our DLP technology.

    The applicability of a DMD for sensing applications can be dependent on not just the DMD, but the chipset itself. For example, the DLPC3430 controller (a display controller, part of the DLPC343x family), which supports the DLP2010 DMD, does not provide pixel accuracy necessary for machine vision applications. Video algorithms which provide substantial benefits for display applications don't translate as well to sensing patterns.

    We are actually rolling out a new family of chipsets (The DLPC347x family) which supports sensing applications for our smaller pico DMDs. A product preview page for it can be found here:
    www.ti.com/.../DLPC3470

    Please let me know if you have further questions. Stay tuned for more information on these upcoming chipsets.

    Best Regards,
    Philippe Dollo
