The direct beam and the image scattered beam combine to form an interference pattern that is viewed as a three-dimensional image. The technique for making holograms was invented in 1947 by Dennis Gabor of Hungary, but was not widely used until after the laser was invented in 1960. Salvador Dali used holography to make works of art. ]]></baseNameString></baseName>  </occurrence></topic>  <association>    <instanceOf>      <topicRef xlink:href="#related-terms"/>    </instanceOf>    <member>      <roleSpec>  <topicRef xlink:href="#related-term"/>      </roleSpec>      <topicRef xlink:href="#http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31371214"/>    </member>    <member>      <roleSpec>  <topicRef xlink:href="#related-term"/>      </roleSpec>      <topicRef xlink:href="#http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31431573"/>    </member>  </association>  <association>    <instanceOf>      <topicRef xlink:href="#broader-narrower"/>    </instanceOf>    <member>      <roleSpec>  <topicRef xlink:href="#narrower"/>      </roleSpec>      <topicRef xlink:href="#http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31431573"/>    </member>    <member>      <roleSpec>  <topicRef xlink:href="#broader"/>      </roleSpec>      <topicRef xlink:href="#http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31401998"/>    </member>  </association>  <association>    <instanceOf>      <topicRef xlink:href="#related-terms"/>    </instanceOf>    <member>      <roleSpec>  <topicRef xlink:href="#related-term"/>      </roleSpec>      <topicRef xlink:href="#http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31431573"/>    </member>    <member>      <roleSpec>  <topicRef xlink:href="#related-term"/>      </roleSpec>      <topicRef xlink:href="#http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31371214"/>    </member>  </association>  <association>    <instanceOf>      <topicRef xlink:href="#broader-narrower"/>    </instanceOf>    <member>      <roleSpec>  <topicRef xlink:href="#narrower"/>      </roleSpec>      <topicRef xlink:href="#http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31452776"/>    </member>    <member>      <roleSpec>  <topicRef xlink:href="#broader"/>      </roleSpec>      <topicRef xlink:href="#http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31431573"/>    </member>  </association>  <association>    <instanceOf>      <topicRef xlink:href="#broader-narrower"/>    </instanceOf>    <member>      <roleSpec>  <topicRef xlink:href="#narrower"/>      </roleSpec>      <topicRef xlink:href="#http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31452773"/>    </member>    <member>      <roleSpec>  <topicRef xlink:href="#broader"/>      </roleSpec>      <topicRef xlink:href="#http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31431573"/>    </member>  </association>  <association>    <instanceOf>      <topicRef xlink:href="#synonym"/>    </instanceOf>    <member>      <roleSpec>  <topicRef xlink:href="#non-preferred-term"/>      </roleSpec>      <topicRef xlink:href="#http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31431574"/>    </member>    <member>      <roleSpec>  <topicRef xlink:href="#preferred-term"/>      </roleSpec>      <topicRef xlink:href="#http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31431573"/>    </member>  </association>  <association>    <instanceOf>      <topicRef xlink:href="#synonym"/>    </instanceOf>    <member>      <roleSpec>  <topicRef xlink:href="#non-preferred-term"/>      </roleSpec>      <topicRef xlink:href="#http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31431575"/>    </member>    <member>      <roleSpec>  <topicRef xlink:href="#preferred-term"/>      </roleSpec>      <topicRef xlink:href="#http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31431573"/>    </member>  </association></topicMap>
