Abstract

são aqui descritas técnicas para determinar a posição de um feixe de luz em um dispositivo de conformação de feixe. um recurso pode ser formado no dispositivo de conformação de feixe para afetar pelo menos uma porção de um feixe de luz quando o recurso é iluminado pelo feixe de luz. quando o feixe de luz é direcionado para o recurso no dispositivo de conformação de feixe, um sinal de detecção de recurso pode ser gerado por um detector em resposta à detecção, pelo menos, da porção do feixe de luz afetada pelo recurso que foi iluminado pelo feixe de luz. a posição do feixe de luz no dispositivo de conformação de feixe em um instante de tempo pode ser então determinada com base, pelo menos em parte, no sinal de detecção de recursos.
