  • Patent number: 10261347
    Abstract: A technique facilitates control over optical transmittance and, in some applications, the technique may be carried out without using moving mechanical parts. A system may comprise a light source and an optical fiber line, e.g. a plurality of optical fiber lines, in optical communication with the light source. An electrochromic device is positioned along each optical fiber line and may be selectively operated via electrical inputs to control optical transmittance along the corresponding optical fiber line. When plural optical fiber lines are employed, the corresponding plurality of electrochromic devices may be operated to also provide control over optical path selection. In fluid analysis operations, at least one sample chamber for receiving fluid samples may be positioned along a corresponding optical fiber line to enable analysis of light directed into the fluid sample as controlled by the corresponding electrochromic device.
