Thermochromic sensors provide an intuitive and real‐time solution for monitoring the local
temperature with naked eyes. Conventional thermochromic sensors often utilize either …

Speckle patterns are a powerful tool for high-precision metrology because they enable
remarkable performance in relatively simple setups. Nonetheless, researchers in this field …

Sensors that measure their motion with respect to the surrounding environment (ego-motion
sensors) can be broadly classified into two categories. First is inertial sensors such as …

Current biometric modalities include fingerprint, palm, voice, face, gate, iris and even DNA
recognition. Another known biometric technique involves subject identification using retinal …

Here, we report a fiber-optic point-based sensor to measure temperature and weight based
on correlated specklegrams induced by spatial multimode interference. The device is …

Images of laser scattering patterns generated by bacteria in urine are promising resources
for deep learning. However, floating bacteria in urine produce dynamic scattering patterns …

Absorption spectroscopy is widely used to detect samples with spectral specificity. Here, we
propose and demonstrate a method for enhancing the sensitivity of absorption spectroscopy …

We report on recent advances in the use of inexpensive polymer optical fibres (POFs) for
sensing applications in avionics. The sensors analysed in this manuscript take advantage of …

Since light propagation in a multimode fiber (MMF) exhibits visually random and complex
scattering patterns due to external interference, this study numerically models temperature …
