This tutorial presents a guided tour of laser feedback interferometry, from its origin and early
development through its implementation to a slew of sensing applications, including …

Raman microscopy systems are becoming increasingly widespread and accessible for
characterising chemical species. Microfluidic systems are also progressively finding their …

The Meter model (a four-parameter model) captures shear viscosity–shear stress
relationship (S-shaped type) of polymeric non-Newtonian fluids. We devise an analytical …

The progress on laser feedback interferometry technology is reviewed. Laser feedback
interferometry is a demonstration of interferometry technology applying a laser reflected from …

Optical rangefinders based on Self-Mixing Interferometry are widely described in literature,
but not yet on the market as commercial instruments. The main reason is that it is relatively …

We present an overview of the applications of self-mixing interferometer (SMI) to tasks of
interest for mechanical engineering, namely high-resolution measurement of linear …

Optical feedback interferometry (OFI) sensors are experiencing a consistent increase in their
applications to biosensing due to their contactless nature, low cost and compactness …

The novelty of Self-mixing interferometry is represented by the combination of high accuracy
and contactless operation with compact, very-low-cost and user-friendly setup. This paper …

We demonstrate a flow-meter sensor using a bare laser diode (LD) as a self-mixing
interferometer and no additional lens nor optical component. The diode is placed directly on …

Precise monitoring of fluid flow rates constitutes an integral problem in various lab-on-a-chip
applications. While off-chip flow sensors are commonly used, new sensing mechanisms are …
