Background Biospeckle laser technique is an emerging non-destructive, quality detection
tool used for the evaluation of biological samples. It is rapid, easy to operate and …

This paper presents recent development and applications of thermal lens microscopy (TLM)
and beam deflection spectrometry (BDS) for the analysis of water samples and sea ice …

We report on a statistical tool based on partial least-squares regression (PLSR) able to
retrieve single-component concentrations in a multiple-gas mixture characterized by …

Flying insects are of utmost importance in ecology and for human living conditions. Certain
species serve as indispensable pollinators to ensure the availability of food stuffs, while …

Cancer is a life-threatening disease that has claimed the lives of many people worldwide.
With the current diagnostic methods, it is hard to determine cancer at an early stage, due to …

GaSe crystals are promising as nonlinear optical converters in the mid-and far-IR ranges.
However, it is challenging to increase the GaSe surface transmittance of 77% with …

This work presents a compact and sensitive refractive index sensor able to evaluate the
concentration of an analyte in a sample. Its working principle leverages on the changes in …

Laser emits light using an optical amplification process that is based on the stimulated
emission of electromagnetic radiation. Thermal and non-thermal approaches are used in …

Small particles contaminated in hard disk drives (HDD) potentially cause damage to the
device, leading to data loss. Hard disk industries, therefore, pay attention to identifying the …

Optical biosensing systems are commonly developed assembling a source, a light–sample
interaction area, and a detector as distinct stand-alone elements. We present a compact …
