Abstract

"INTERFERÈMETRO E PROCESSOS DE MEDIçãO DAS PROPRIEDADES óPTICAS DE UMA AMOSTRA E DE MUDANçAS EM UMA CONDIçãO AMBIENTAL QUE AFETE AS PROPRIEDADES óPTICAS DE UMA AMOSTRA". Proporciona-se um processo e aparelho para medir as propriedades ópticas de amostras de massa. Um feixe de laser de sonda é alimentado em duas subdivisões do aparelho, uma subdivisão de referência e uma subdivisão de medição, ambas as quais contêm fibras ópticas para conduzir as luzes de laser. A subdivisão de medição inclui uma área de espaço livre para montar uma amostra a ser testada. O feixe de sonda é direcionado à amostra no espaço livre. A amostra também recebe luz no espaço livre, ao invés de receber através da fibra óptica, de um segundo laser de bomba. A interação da amostra com o laser de bomba afeta as propriedades ópticas da amostra. Esta mudança nas propriedades ópticas pode ser detectada por comparação dos sinais de saída das subdivisões de medição e de referência."INTERFERÈMETER AND PROCEDURES FOR MEASURING OPTICAL PROPERTIES IN A SAMPLE AND CHANGES IN AN ENVIRONMENTAL CONDITION THAT AFFECTS THE OPTICAL PROPERTIES OF A SAMPLE". A method and apparatus for measuring the optical properties of mass samples is provided. A probe laser beam is fed into two subdivisions of the device, a reference subdivision and a measurement subdivision, both of which contain optical fibers to guide the laser lights. The measurement subdivision includes an area of free space to mount a sample to be tested. The probe beam is directed to the sample in the free space. The sample also receives light in the free space, instead of receiving it through the optical fiber, from a second pump laser. The interaction of the sample with the pump laser affects the optical properties of the sample. This change in optical properties can be detected by comparing the output signals from the measurement and reference subdivisions.
