Optical-based biosensors could improve how the poultry industry detects diseases, viruses and pathogens in both production and processing environments.

“What interferometry gives you is something that’s very sensitive,” Andre Tatar, product manager, Salvus LLC, said at the 2022 Poultry Tech Summit. “Another great thing about this technology is that it’s very adaptable.”

The technology involves the use of a laser light source, a wave guide and an optical detector and could replace the need for sampling tests run in the lab by trained technicians.

What interferometry is

Imagine that you and a friend are standing ten feet away from each other while you throw rocks into a pond. Interferometry measures where the two water ripples meet, Tatar noted.

“Eventually, you’re going to see some waves that are forming where the stones hit the water. And then, you if you wait a little bit longer, eventually these waves will interfere. Once they interfere, it creates a whole new set of waves and measuring these waves is interferometry,” he explained.


The handheld detection technology is portable, meaning that it can easily and reliably identify contaminants, such as diseases, viruses and pathogens, wherever needed in poultry production and processing operations.

Interferometric sensing for the detection of chemical and biological targets in the poultry industry was originally developed at the Georgia Tech Research Institute. Salvus is currently looking for partners to help bring the technology to market. 

Attend the 2023 Poultry Tech Summit

The Poultry Tech Summit is the only event of its kind that connects researchers and entrepreneurs with poultry sector technology experts, financiers, venture capitalists and producers looking for new projects and investments to fund. Since its 2018 inception, this unique conference has facilitated and fast-tracked many pioneering ideas into adoption for the benefit of the poultry supply chain.

Details on the 2023 Poultry Tech Summit will be released in Spring 2023.
