Abstract
"MéTODO PARA CONTROLAR A DISTRIBUIçãO DA INTENSIDADE DE UM CAMPO DE LUZ ESPACIALMENTE PARCIALMENTE COERENTE A UMA DISTâNCIA FINITA A PARTIR DA FONTE OU NO CAMPO DISTANTE". Um método é introduzido para modelar a distribuição da intensidade e melhorar a qualidade de um feixe emitido por meio de uma fonte espacialmente parcialmente coerente com a ajuda de um elemento ótico difrativo periódico (704). Elementos difrativos periódicos não são adequados para modelar campos de luz espacialmente coerentes no sentido descrito na invenção devido ao surgimento de fortes efeitos de interferência construtiva, mas a coerência espacial parcial dos campos de luz emitidos por meio de fontes multimodais suprime esses efeitos. A invenção pode ser aplicada para moldar as distribuições de intensidade emitidas por lasers, diodos emissores de luz, ou fibras óticas seja a uma distância finita da fonte (703) ou no campo distante. A invenção é particularmente vantajosa na modelagem e na melhoria da qualidade de feixes que emanam de lasers eximer de alta energia, lasers semicondutores, diodos emissores de luz de cavidade de ressonância, ou arranjos de lasers ou de diodos emissores de luz (702, 705).
