Abstract

CAPTADOR óTICO Um captador ótico que inclui: um bloco giratório instalado em uma base fixa a ser feita de modo giratório; um suporte acoplado de forma integral ao bloco giratório; um carretel de bobina apoiado por um fio pré-determinado do suporte a ser feito de modo móvel; uma placa base fixada à base e colocada entre o bloco giratório e o carretal de bobina; uma lente objetiva instalada no carretel de bobina, para a focagem de uma luz incidente para a formação de um ponto luminoso em um meio de registro; uma bobina de focagem e bobinas de rastreio instaladas no carretel de bobina, servindo como um trajeto de fluxo de corrente para operações de focagem e rastreio; primeiros ímãs e primeiras culatras internas, e externas instaladas na placa base, confrontantes com a bobina de focagem e as bobinas de rastreio, para a produção de campos magnéticos perpendiculares a corrente fluindo através da bobina de focagem e das bobinas de rastreio para a produção de uma força eletromagnética para acionamento do carretel de bobina; um sistema ótico fixo para a irradiação da luz em sentido do meio de registro e recepção da luz refletida pelo meio de registro e então passada através da lente objetiva; um espelho de reflexão para mudança do trajeto de percurso da luz incidente, o espelho de reflexão instalado no bloco giratório a ser disposto entre a lente objetiva e o sistema ótico fixo; bobinas de inclinação servindo como um trajeto de fluxo de corrente, as bobinas de inclinação instaladas em ambos lados do bloco giratório; e segundos ímãs e segundas culatras internas e externas instalados confrontantemente às bobinas de inclinação, para a produção de campos magnéticos perpendiculares a corrente fluindo através das bobinas de inclinação para a produção de uma força eletromagnética para giro do bloco giratório. Portanto, a inclinação do eixo ótico da luz incidente no e refletida pelo disco ótico através do espelho de reflexão e da lente objetiva pode ser ajustada de acordo com a inclinação do meio de registro, de modo que a luz seja perpendicularmente incidente no e refletida pelo meio de registro em todas oportunidades.
