DLP LightCrafter 3000 and 4500, which one should I choose in DFP experiment?

Dear all,

Now I can buy a DLP LightCrafter to carry out my DFP (digital fringe projection) experiment. It is only possible to buy one of them between DLP LightCrafter 3000 and 4500. From my point of view, one of the biggest difference between them is the resolution and brightness. The DLP LightCrafter 4500 has superior brightness than 3000 and so I wonder to know that does it can completely substitute the DLP LightCrater 3000. In other words, dose DLP LightCrafter 4500 have all the functional that DLP LightCrater has. If so, I can only choose the DLP LightCrafter 4500.

 

Further, I am not sure about that the DLP LightCrafter 3000 has enough brightness even the DFP experiment is carried out in dark room for the specialty of our experiment. Our experiment is to measure the object in water with glass tank size approximately 30cm*30cm*20cm. In this case, I think the measured image will be very dark if the DLP LightCrafter 3000 is used, due to scattering and absorption of water and glass. Is it safer to use DLP LightCrafter 4500 in this case.

 

Overall, my questions are that dose DLP LightCrafter 4500 can completely replace the DLP LightCrafter 3000 and does DLP LightCrafter 3000 have enough brightness to measure the object in water.

 

Great thanks.

  • Hello Xinjun,

    If your care about is brightness and resolution, i would definitely recommend DLP LightCrafter 4500.

    Apart from the resolution and brightness. few things you should be aware about  both the platforms -

    1. High speed refresh for pre-loaded data , LightCrafter 4500 give upto 48 binary patterns worth of memory where as LightCrafter 3000 it is 96.

    2. In DLP LightCrafter  4500 for a pattern sequence occupying > 48 binary patterns; the max speed is determined by the time taken for loading the 24-bit pattern from flash to frame-buffer. This time is any where b/w 70ms to 200ms. Where as in case of DLP LightCrafter > 96 binary pattern, it starts from 20ms onwards.

    3. If the Pattern data is is sent real-time via RGB video interface, the new DLP LightCrafter 4500 has advantage, since it supports pixel clock upto 150MHz and Video frame-rate upto 120Hz full resolution 912x1140.

    I hope this helps in making your decision better.
