A fibre-optic sensor for measuring a physical quantity, such as a pressure, force, acceleration or tilt, includes an optical fibre having a measurement section for measuring a strain in the fibre, and first and second structural members. The optical fibre is connected to a first fibre connection section of the first structural member and to a second fibre connection section of the second structural member. The first and second connection sections are arranged on opposite sides of the measurement section, such that at least the measurement section is suspended between the first and second fibre connection sections. At least one of the structural members is movable relative to the other in dependence of the physical quantity that is measured. The structural members are made from materials having different coefficients of thermal expansion such that a temperature induced strain in said optical fibre due to a temperature change is reduced.

Embodiments herein describe systems, methods, and devices for determining reticle temperature based on reticle shape measurements. The system can include an illumination path configured to direct radiation onto a patterning device and a detection path configured to direct a portion of the radiation after the portion interacts with the patterning device onto a detector configured to output a signal representative of the portion of the radiation beam. A controller can receive the signal and determine information about a physical characteristic or alignment of the patterning device and use this information to estimate a load temperature of the patterning device. The controller or another controller can use the estimated load temperature to compensate for temperature-induced magnification of the patterning device. The controller or another controller performs the compensation by adjusting the positioning of a stage or lens of the system.
