Light Acquisition

Light Acquisition

In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Generating Electromagnetic Radiations

Generating Electromagnetic Radiations

The German physicist Heinrich Hertz (1857–1894) was the first to generate and detect certain types of electromagnetic waves in the laboratory. Starting in 1887, he performed a series of experiments that confirmed the existence of electromagnetic waves and verified that they travel at the speed of light. Hertz used an alternating-current RLC (resistor-inductor-capacitor) circuit that resonated at a known frequency and connected it to a loop of wire. High voltages induced across the gap in the...

Maximum Power Transfer

Maximum Power Transfer

Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.
By substituting the entire circuit with...

Photoluminescence: Applications

Photoluminescence: Applications

Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...

Photoelectric Effect

Photoelectric Effect

When light of a particular wavelength strikes a metal surface, electrons are emitted. This is called the photoelectric effect. The minimum frequency of light that can cause such emission of electrons is called the threshold frequency, which is specific to the metal. Light with a frequency lower than the threshold frequency, even if it is of high intensity, cannot initiate the emission of electrons. However, when the frequency is higher than the threshold value, the number of electrons ejected...

Area of Science:

Optical Communications
Computer Engineering
Illumination Engineering

Background:

Indoor visible light communication (VLC) systems require uniform power and illumination for reliable performance.
Achieving uniform distribution is challenging due to transmitter configurations and signal propagation.

Purpose of the Study:

To propose an evolutionary algorithm-based optimization scheme for uniform received power and illumination in indoor VLC.
To analyze the impact of transmitter optical intensity adjustments on system performance.
To investigate the influence of receiver field of view on optimization outcomes.

Main Methods:

An evolutionary algorithm was employed to dynamically adjust the relative optical intensity of transmitters.
Simulations were conducted for three distinct distributed lighting configurations.
Key performance indicators such as received power dynamic range, illuminance uniformity ratio, root mean square delay spread, and bandwidth were evaluated.

Main Results:

The optimization scheme reduced the dynamic range of received power to approximately 40.0% of the peak value.
Illuminance uniformity ratio improved significantly, reaching up to 0.70.
The impact on root mean square delay spread and bandwidth was found to be negligible.

Conclusions:

The proposed evolutionary algorithm effectively enhances illumination and power uniformity in indoor VLC systems.
Dynamic adjustment of transmitter intensity is a viable strategy for improving VLC performance.
Receiver field of view is a critical parameter influencing the success of the optimization process.
