Abstract

Reflective sensors involving optical fibers are very popular due to low cost and EMI insensitive. In this paper, a new concept is described regarding proximity sensors based on ball-lensed optical fibers (PSBBOF). Two types of sensors are presented: (1) Type A with one transmitting and four receiving optical fibers and (2) Type B with one transmitting and eight receiving optical fibers. In both PSBBOF types ball-lensed optical fibers are used as a receiving line. Sensitive of both PSBBOF is compared to sensitive of sensors with the same configurations, but involving cleaved optical fibers. All developed sensors were tested at two wavelengths: 850 nm and 1300 nm. As a refractive surface the silicon wafer was used.
