  • Forum Post: Re: what is the light intensity delivery threshold for DMD

    ShengWang8120
    Thank you for the information. We will expand laser beam to about 1cm^2, even though the femtosecond laser still make very strong peak flux to DMD (the peak flux we need is around the order of 100000W/cm^2). The laser pulse is about only 100 femtoseconds long, then after about 10 nanoseconds drak duration...

    I also calculate the average power of what you are describing to be at about 1W/cm^2, which if the beam were continuous at this power is within the ability of the DMD to dissipate. This agrees with your numbers. The DMD should be able to handle the load; I estimate each pulse in the operation you...

  • Forum Post: Separating the projector module from processor

    matt kenyon
    For my research I am trying to separate the pico projector processor board from the DMD projector module. What do you think is the maximum distance between DMD module and processor board? Does anyone know the part number/name of the socket connecting the processor board and DMD module?

    Hi there, I've read all of the new docs (1505 datasheet, etc), and have spent a great deal of time with a few Picos on a specific project, I have a recommendation. Suggestion: In future Pico eval kits, it would be fantastic to expose the 1505's CPU I/F to the developer. Currently, it's...

    DLP technology is well known for powering office and classroom projectors, HDTVs and digital cinema solutions. Soon after DLP chips were commercially introduced, developers and researchers began requesting access to DLP technology to help fuel their innovative ideas. Several of those ideas were in areas...

    For use in an industrial structured light application, it is required to control the state of the individual pixel output color and brightness in the PICO.

  • Forum Post: DLP-Link projector issue

    Mathew Orman
    Dear Sir or Madame, I have just found out that DLP-Link does not work on all projectors. Projectors do not use checker board 3D content and operate at 120 Hz. The problem is lack of 3D content sync resulting in random pseudo stereoscopic scene projection. It looks as if DLP-Link implementation...

    Hi, I would like to use the DMDs unique speed and precision for a spatial light modulator application. The DMD will be placed into the fourier plane. Unfortunately it seems that the DMD chips are not particularily flat, the wavefront distortion is on order 10 fringes , as can be measured interferometrically...

    I have been reading this forum looking for others that have tried using infrared laser light, specifically CO2 laser light about the 10.6 um wavelength, and have not found what I am looking for. From what I can gather, the 0.55 XGA Series 450 DMD does not handle NIR light, but the 0.17 HVGA DDR Series...

    Hello, we are developing a very high speed structured light illumination system. The 4000Hz binary pattern given by the DLPC3000 controller is not fast enough for our needs. The miccromirrors switching time is only a few microseconds, which is very great. The speed bottleneck seems to be the DMD...
