Since the advent of the COVID-19 pandemic, face-to-face outreach has been gradually replaced
by dissemination through social networks. However, the use of social networks for outreaching is not easy since there is an important risk of biasing the communication by converting it into an exclusively one way channel. In this contribution, we explain how a transmedia perspective can transform a regular activity, as a photo contest for the International Day of Light 2021, into an interactive comprehensive and functional event in Twitter, Instagram and Twitch.

Low-cost interrogation system for dynamic sensor applications using a resin based fiber Fabry Perot filter

In this paper a low-cost interrogator for dynamic sensor applications is proposed. The scheme is based on the edge filtering technique, where the slope of a resin based Fabry-Perot (FP) filter is used to actively filter the power of a narrowband laser. The interrogator is composed of a laser, circulator, photodetector, Arduino board and laptop. The system was first characterized and then, the measurement of a pulse wave signal was performed by embedding the FP sensor in a 3D printed elastic membrane and reading the signal through the proposed interrogator.

Balanced differential common-path interferometer with low cyclic error and no zero-drift

In the interferometry-based optical metrology of length, many sources of error of concern could be mitigated at the very foundation, i.e. with the careful design of the interferometer's optics.We report on an optical arrangement for a differential common-path plane interferometer with symmetric, coaxial and balanced arms robust against the geometric errors and thermo-mechanical effects. The experimental results indicate excellent performance with periodic errors lower than 0.1 nm and the long-term zero drift stability with fluctuations better than a nanometre over several days.
