  • Forum Post: Where DISCOVERY1100 or DISCOVERY 3000 starter KIT could be purchased

    Eugene Braginets
    Hi All, Could somebody please direct me - when I can see actual prices for DLP Discovery 1100 or DLP Discovery 3000 systems, and accordingly buy it. Reason is one - price for Discovery 4000 seemed to be to high for us awhile.... ;( Thanks! PS: We're - small company building projection system...

  • 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?

    Eric Johnston
    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...

    Blake
    I'm considering DLP micromirrors for an application requiring fast switching speeds for the entire array. I need all the mirrors to be able to switch back and forth between on and off states at rates of < 1 microsecond. I understand this will require global resets to update all the mirrors...

    MarcM
    Hello. I work for Stewart Filmscreen and recently I have been questioned by a few dealers about the differences between these 2 units. The main concern is that our dealers have 'heard' that the dark chip 3 is designed more for dedicated theater environments, and the Dark Chip 4 is intended...

    Hello, we're planning to upgrade our product design based on DLP. We need to increase the illuminating intensity. According to the specification, vis DMD recommended 25W/sq cm use continuous wave(400nm-800nm), but for our design we used an LD laser(405nm) as light source. I just wondered what...

    Francis Esmonde-White16623
    I have a discovery 4000 kit with the .55 XGA chip. I'm controlling the DMD through Matlab via the .OCX (ActiveX) file provided. Overall, it's an amazing piece of technology. Fortunately, there are built-in Matlab functions that allow me to call the .OCX routines to control the DMD without rebuilding...

    Francis Esmonde-White16623
    Hi Martha, Like you, we have too many images to pre-generate all the bin files. However, I don't think that your method of sweeping through pixels one-at-a-time is the way to go. You are probably doing some kind of compressive sensing, and there are much better algorithms than reading one pixel...

    Jinyang, Are you controlling the DMD through ActiveX or are you directly communicating with it through the DLL? I get a "Catastrophic Failure" error code when I try to get the DMD to communicate with Labview through ActiveX. Am I missing something??? Here is the block diagram for my small...

    Nick Conway
    After exhaustively exercising my Discovery 4000 1080p board, I can't seems to get rid of stuck vertical lines of pixels (maybe a line every 50 pixels is stuck? its unclear since I've yet to map my DMD to a camera and there are only lines on the right half of the display). I've attempted to...

    Hey Fizix, We are currently using a 760nm Super-luminescent Light Emitting Diode (SLED) as a input light source to do spatial light modulation. But the experimental result was totally out of my expectation. After reflected by DMD with all pixels being turned on ("ONE"), the output beam can't...

    Jack, The DMD with the largest dimension micromirror is the .7 XGA (1024x768) which is available for the DLP Discovery 4100 kit. This DMD has a mirror pitch of 13.6 um. This DMD is available with a NIR window anti-reflection coating. See this link for transmission curves: http://focus.ti.com/analog...

    Hello Peter, Welcome to the DLP & MEMS E2E forum. The flat state of a DMD mirror is not an operational position. When a DMD is operating, each mirror is in either the +12 degree or -12 degree tilt position - unless the DMD is parked. In the parked condition, all of the mirrors will be in a...

    In fact, we use DMD as 3D measure, the current DMD(HVGA) resolution is a little small, VGA size is the best for our product.

    Hello, We are very interested in DLP technology and we want to add the projection function into our system.

    Hiren, I can not answer this question, because it is not clear what the question is. It may be possible to use DMD for IR calibration, but more specific information about the task is needed. Could you say more about the need, or the ideas for doing this IR calibration? Best regards, Pascal

    Pascal DLP
    Hiren, Thank you for explaining a little more. What wavelength or range of wavelengths are you concerned with? The mirrors of DMD devices are aluminum - with the reflectivity profile which is characteristic of aluminum - which is good in the near IR. However, there are two further limitations for...

    Markus, Thank you for explaining further. Also, thanks for the link - it is very helpful. As for the comparison of a laser mirror vs a DMD, the linked article does show a contour map of a DMD which is very interesting - taken by a " phase shifting interferometer". It is not clear whether...

If you need a replacement for one in your projector, you should contact the manufacturer of the projector directly...
