Special Issue Information

Dear Colleagues,

It is our pleasure to announce a second volume of this Special Issue devoted to instruments based on photonics technology and devices. Photonics has been widely recognized as a Key Enabling Technology (KET), and is expected to drive the development of a new class of advanced instruments in a wide area of challenging applications, as it can provide new disruptive approaches in current established technological solutions, with an anticipated high global market impact.

The purpose of this Special Issue is to identify diverse and promising photonic technologies at a sufficiently high maturity level to enable the development of advanced instruments. The versatility of photonics technology allows its adaptation in many different application areas, such as telecommunications, sensing, aeronautics, biomedical, defense and security, demonstrating the advantages of photonic implementation and its unique capabilities over other competitive technologies.

Photonics technology and industry is rapidly developing into an interdisciplinary field combining active research in a number of fields ranging from novel materials, metamaterials, nanotechnology, advanced processing techniques, environmental control and packaging to specialty electronic or even all-optical instrumentation. This mixture has a direct effect on the operational requirements and associated complexity of instrumentation, consequently setting certain restrictions to the wide deployment of photonics as there is an adequate standardization level in is still lacking in several cases.

Therefore, despite photonics' versatility and unique capabilities, the development of instruments is still at the initial stage for several cases, leaving thus an area of open issues for further fundamental and applied research that we seek to indicatively cover in this thematic Issue.

We invite contributions in the form of expert comprehensive reviews or research articles dealing with photonics technology focused on instrumentation in connection to current or emerging applications. The scope is to create a well-balanced collection of papers that will help to map the penetration of photonics instruments in various application areas and identify the perspectives and open challenges for future development.

Contributions are expected to deal with, but are not limited to, the following areas:

  • Photonic active and passive devices;
  • Fiber and waveguide photonic devices and instruments;
  • Photonic sensors;
  • Remote photonic instruments;

The measurement system proposed in this paper, using a measuring arm and line structured light, has a wide range of applications. To improve the scanning efficiency, the system outlined in this paper uses two single-line structured lights to form crosshair structured light, which we combine with a measuring arm to form a comprehensive scanning measurement system. The calibration method of Zhengyou Zhang and a calibration board are used to complete parameter calibration of the sensors and cameras, as well as hand–eye calibration of the measuring arm. For complex curved-surface objects, this system extracts the cross-line structured light optical center location, which suffers from ambiguity. Therefore, we introduce the use of periodic control of the two line structured light sources in order to resolve the light extraction polysemy. Our experimental results indicate that the proposed system can effectively satisfy the function of crosshair structured light scanning of large, complex surfaces. Full article

A low-cost medium-power carbon dioxide (CO2) laser system is designed, constructed, and characterized to produce coherent, monochromatic laser radiation in the infrared region. The laser cavity is simulated and designed by using ZEMAX optic studio. A switch-mode high-tension pump source is designed and constructed using a flyback transformer and simulated using NI Multisim to study the voltage behavior at different node points. A prototype cooling system/chiller is designed and built using thermo-electric coolers (TEC) to remove the excess heat produced during laser action. Various parameters, such as pumping mechanism, chiller stability, efficiency, output power, and current at different applied voltages, are studied. The chiller efficiency at different output powers of the laser is analyzed, which clearly shows that the chiller’s cooling rate is good enough to compensate for the heat generated by the laser system. The center wavelength of the carbon dioxide laser is 10.6 μm with an FWHM of 1.2 nm simulated in the ZEMAX optic studio. The output beam penetration through salt rock (NaCl), wood, and acrylic sheet (PMMA) at various output powers is analyzed to measure the penetration depth rate of the CO2 laser. Full article

We present a concept that enables the determination of the complex refractive index of attenuating media from two critical angles, measured sequentially at two interfaces between a single sample and two different prisms. The proposed method is general in that it applies with s and p polarisation states, thus it is suited for the characterisation of isotropic as well as anisotropic media. Uncertainty analysis indicates that relative error in the determination of the real (imaginary) index can be less than 10−4 (in the order of 10%), respectively. Full article

In the realm of space exploration, solid rocket motors (SRMs) play a pivotal role due to their reliability and high thrust-to-weight ratio. Serving as boosters in space launch vehicles and employed in military systems, and other critical & emerging applications, SRMs’ structural integrity monitoring, is of paramount importance. Traditional maintenance approaches often prove inefficient, leading to either unnecessary interventions or unexpected failures. Condition-based maintenance (CBM) emerges as a transformative strategy, incorporating advanced sensing technologies and predictive analytics. By continuously monitoring crucial parameters such as temperature, pressure, and strain, CBM enables real-time analysis, ensuring timely intervention upon detecting anomalies, thereby optimizing SRM lifecycle management. This paper critically evaluates conventional SRM health diagnosis methods and explores emerging sensing technologies. Photonic sensors and fiber-optic sensors, in particular, demonstrate exceptional promise. Their enhanced sensitivity and broad measurement range allow precise monitoring of temperature, strain, pressure, and vibration, capturing subtle changes indicative of degradation or potential failures. These sensors enable comprehensive, non-intrusive monitoring of multiple SRM locations simultaneously. Integrated with data analytics, these sensors empower predictive analysis, facilitating SRM behavior prediction and optimal maintenance planning. Ultimately, CBM, bolstered by advanced photonic sensors, promises enhanced operational availability, reduced costs, improved safety, and efficient resource allocation in SRM applications.

Is Raman spectroscopy applicable for analytical purposes? Although Raman spectroscopy is a commonly used technique for analyzing sample characteristics and has numerous benefits, it still has several significant limitations that hinder the current tendency to produce the same results regardless of location, equipment, or operator. Overcoming these drawbacks may help to further the development of personalized medicine, diagnosis and treatment, the development of work protocols, and the pursuit of consistent and repeatable performance across all fields. Interlaboratory studies are currently the best way to do this. In this study, we reviewed the interlaboratory studies on Raman spectroscopy conducted to highlight the importance of moving to quantitative analysis in controlled environments. The advantages of Raman spectroscopy, including its high molecular specificity, short spectrum acquisition time, and excellent component identification capabilities, were clearly stated in all experiments. The Raman spectroscopy lab is taking small steps toward analytical applications by figuring out how to accurately predict concentrations in the relevant range of concentrations, developing and verifying the technology, and producing homogenous samples for those investigations.
