title: Additive manufacturing of a monolithic optical force sensor based on polarization modulation.
abstract: One of the specific interests of optical sensors is their compatibility with harsh environments. The polarization modulated force sensor we propose offers this advantage, in addition to low cost and ease of manufacturing thanks to its acrylate 3D printed monolithic design. All the polarization control is indeed achieved using the geometry of a single component making unnecessary future alignments. The complex geometry of the transducer is obtained thanks to the 3D printing process. This process and the resulting material optical properties are described. The sensor concept and the fabrication method are experimentally investigated. A monolithic force sensor in the required range of 20 N is exhibited for application in the field of MR-compatible robotics. The potentiality of 3D printing for optical application in the design of the force sensor is illustrated.
