About pinhole collimeter

  1. Jul 28, 2011 #1
    hello friends i would like to know about how to design a pinhole collimeter for soft xray detectation
    i have some question about this
    i know that for specific wave length of light aparture of pin hole should be 1.9sqrt(focal lenght x wave length of light)

    but i wave to know if i place 10 detectators at 10 cm focal length in array and i have subject distance is about 50cm and subject is circular in diameter of 50cm so what would be the spatial resolution of the camera
    if any one know about this please tell or suggest the way that i can go forward in this regard

    thankyou.
