“…Light technology has been through a long evolution since more than a century ago marked by the invention of incandescent light and a halogen lamp [ 6 ]. Laser subsequently emanated and profoundly explored into a more complex integration such as in the development of helium-neon laser as the first gas laser at Bell Labs [ 7 ] and the semiconductor laser diode at General Electric using GaAs material [ 8 ].…”

The notion of surface plasmon resonance (SPR) sensor research emerged more than eight decades ago from the first observed phenomena in 1902 until the first introduced principles for gas sensing and biosensing in 1983. The sensing platform has been hand-in-hand with the plethora of sensing technology advancement including nanostructuring, optical technology, fluidic technology, and light source technology, which contribute to substantial progress in SPR sensor evolution. Nevertheless, the commercial products of SPR sensors in the market still require high-cost investment, component, and operation, leading to unaffordability for their implementation in a low-cost point of care (PoC) or laboratories. In this article, we present a comprehensive review of SPR sensor development including the state of the art from a perspective of light source technology trends. Based on our review, the trend of SPR sensor configurations, as well as its methodology and optical designs are strongly influenced by the development of light source technology as a critical component. These simultaneously offer new underlying principles of SPR sensor towards miniaturization, portability, and disposability features. The low-cost solid-state light source technology, such as laser diode, light-emitting diode (LED), organic light emitting diode (OLED) and smartphone display have been reported as proof of concept for the future of low-cost SPR sensor platforms. Finally, this review provides a comprehensive overview, particularly for SPR sensor designers, including emerging engineers or experts in this field.

The radiating power with sine waveform is required for modulated infrared thermography nondestructive testing. Sine voltage was applied by former authors for deriving sine power waveform. The theory mode of infrared lamp is proposed. According to numerical solution and FFT analysis, high frequency components are included in the radiating power waveform, when sine voltage is set to drive the lamp. A light intensity sensor was utilized for monitoring the real-time radiating power, and a close-loop power tracking system was constructed. Fractional order sliding mode controller was selected in the tracking system, for its robustness and flexibility property. The reachability of the controller is proved and the calculation formulas of reach time are given. In experiment, the tracking results with both PID and sliding mode controller were derived. Lower tracking overshoot and better robustness was derived through the sliding mode controller, compared with the PID counterpart.

The present work is a focus on getting selectivity of the products using intense heat and employing borax vacant orbitals for catalysis. A DC‐arc‐type reactor was used for the pyrolysis of waste polyethylene. The third point of its novelty is utilization of the solar energy as arc through photovoltaics and indoor use of solar energy for high‐temperature heating. The combined action of high temperature, faster heating, and vacant orbital catalysis is intended for the product enhancement, selectivity of the process, and efficient management of the waste plastics. The process involves photovoltaic transformation of sunlight into electrical energy followed by storage in lead acid battery and discharge of heat in the form of arc. A graphite rod was used for the arc in the reactor. The high temperature and faster heating pyrolyzed the waste polyethylene into oil, fuel gas, and char. The reactor's efficiency was found to depend upon the rod length and time. The product gases were analyzed by chemical tests while the oil was analyzed using GC–MS. The gaseous product was highly combustible. The oil density (0.7 g/cm3) was found in gasoline range. The chemical tests indicated that the gas contains alkanes, alkenes, alkynes, and hydrogen gas.
