  • Modular scatterometer with interchangeable scanning heads
    Patent number: 5196906
    Abstract: An optical measurement device produces quality light scatter measurements using Bidirectional Reflective Distribution Function (BRDF) techniques to analyze data generated from an accurate, portable, relatively inexpensive scatterometer. The scatterometer is provided with interchangeable scanning heads, each scanning head being equipped with ROM data storage containing certain configuration information about the scanning head. The use of the interchangeable scanning heads allows the present invention to make measurements of light scatter for a wide variety of applications and samples under a variety of environmental conditions where scatter measurement has previously not been feasible.
