DLP Technology - Maximum Distance Range for Structured Light

Other Parts Discussed in Thread: DLP2010NIR, DLP4500NIR, DLP4500

Hi All,

we are developing an active vision SWIR system (Short Wavelength Infra-Red) with an illuminator at 1550nm that projects structured light (dotted matrix or something like). The area that we have to enlighten is about of 10 meter x 10 meter; the maximum distance between illuminator and the area is about 14 meter.

Is it possibile to create such structured light for our application or area/distance above mentioned is too big for DLP technology?

If it is possible, please can you suggest your best solution and evaluating kit?

Thanks in advace for your support,

Savino

    Hello Savino,

    Welcome to the DLP E2E Forum.

    DLP technology could still work, but how well depends on several things including the level of accuracy you wish to obtain, the amount of ambient light at or near 1550nm and your sensor capabilities.   We have two DLP chipsets specified for 1550nm, the DLP4500NIR and the DLP2010NIR. The DLP4500NIR is a physically larger array compared to the DLP2010NIR. In addition, it is available in the thermally enhanced FQD package. The larger array and thermally enhanced package would be beneficial in maximizing the possible illumination on your target object that is 14 meters away.

    The TI Design for DLP 3D Machine Vision is a good resource to continue your research. It is based on the DLP4500 visible wavelength chipset.

    Regards,

    Eric
