DarkPulse closes $850K in bridge funding to transform the Brillouin Sensors with distributed fiber sensor solutions

For many years, optical fibers have commonly been used as communication channels where light waves propagate along haul distances. In this situation, the fibers are isolated from the external perturbations (measurands) by means of cabling techniques.

Brillouin scattering (also known as Brillouin light scattering or BLS), named after Léon Brillouin, refers to the interaction of light with the material waves in a medium. By enhancing the environmental influences on the properties of the light that travels into the waveguide, the fibers can be used to detect, monitor, and even measure external perturbations in an integral or distributed format.

Historically, however, Brillouin Sensors have failed due to temperature/strain cross-sensitivity issues and poor resolution. This is inherent with Brillouin optical time-domain analysis (BOTDA) bright pulse systems. Within the last decade, a new approach towards improved spatial resolution was invented, called dark pulsing, that allowed spatial resolutions in the sub-meter range. Without these spatial resolutions, conventional BOTDA sensing systems are only practical for fire detection and large-scale strain changes.

Enter Dark Pulse, a Scottsdale, Arizona-based tech startup that presents a BOTDA system based on dark-pulse scattering that provides improved resolution, accuracy, and acquisition time over conventional BOTDA systems, without the severe limitations on sensing length often imposed by other high-resolution techniques.

The Theoretical validation of the method is given, and experimental results are presented that demonstrate 20-mm resolution strain measurements with an accuracy of ±20, which is the highest spatial resolution yet reported for a BOTDA system.

Today, Dark Pulse announced it has closed bridge funding in the amount of $850,000.00 to retire old notes aid in the demonstration of the Company’s sensor technologies and the hiring of key personnel.

The Company has negotiated and closed a private convertible loan with a fixed conversion price that will allow it to implement its near-term sales-focused goals. The loan will also facilitate the Company’s desire to continue its path to revenues while implementing its strategy to up-list to the OTCQB as part of its future plan to trade on larger markets such as the NASDAQ. Dark Pulse technology is used in pipeline, mine safety, and oil & gas.

Founded in 2018 by Dennis M. O’Leary, DarkPulse is focused on the manufacture, sale, installation, and monitoring of laser sensing systems based on its patented BOTDA dark-pulse sensor technology (the “DarkPulse Technology”) which provides a data stream of critical metrics for assessing the health and security of the infrastructure.

Commenting on the funding, Dark Pulse founder and CEO said: “Dark Pulse has successfully closed bridge funding that we believe will ensure its operations for the next several months.”

O’Leary added: “We believe that the fixed conversion price negotiated compared to the current market price indicates the strength of our position and both short and long-term potential in the markets.” He continued, “The funds will be utilized to retire past notes, fund product demonstrations, and pay for key personnel hires as the Company continues expanding its operating capabilities.”
