About PSI
Phase Sensitive Innovations
Phase Sensitive Innovations (PSI) is a privately owned company specializing in millimeter wave (mmW) imaging technology, systems and components.
Millimeter-wave Imaging
Millimeter-wave imaging has the unique potential to penetrate through poor weather and atmospheric obscurants to create high-resolution ’see-through’ images.
Our Mission
To produce high-quality, reliable millimeter wave imaging systems and photonic components that serve to fuel the growing needs and requirements of growing markets.
Products
In addition to millimeter wave imaging some of the other applications for our technology include; 5G Cellular Networks and Cellular backhaul at 28 GHz, 37 GHz, 39 GHz and 64 GHz as well as millimeter wave test instrumentation and autonomous or assisted vehicles as a Radar & Lidar enhancement.

All of our integrated modules are entirely manufactured in-house and custom-built to meet our clients’ specifications
Phase Sensitive Innovations leverages years of research and development in RF Photonics to bring several discrete components to market. See our standard offerings below. For custom solutions fitting your individual needs, browse our Services or Contact us directly with queries.
