About Our Technology

We have developed an advanced optical sensing device designed to measure and monitor fluid surfaces. Utilising digital holography and digital processing, our device provides real-time 3D profile reconstructions of transparent liquids, thin films, and other reflective surfaces.

This technology is adaptable to various scenarios, from room temperature to cryogenic environments, making it ideal for a wide range of industrial applications.

The Challenge

Mapping fluid interfaces and surfaces in both space and time is a complex task due to their diverse physical and chemical properties. Industries such as food production, semiconductor fabrication, adhesive and bonding, and automotive manufacturing face significant challenges in ensuring the quality and integrity of products like surface coatings, liquid samples and thin films.

Traditional monitoring methods often involve invasive techniques, small coverage area, and are limited by the conditions of the working environment, making real-time, non-destructive measurement challenging.

Our Solution

Our optical sensing device addresses these challenges with a streamlined hardware setup using off-the-shelf optical components and a fast machine vision or scientific camera. The sensor's modular design ensures portability and allows operation in both visible and infrared spectrums. It dynamically probes areas using a low-power expanded laser beam, ensuring safety and compliance with standard health and safety requirements.

We employ a proprietary signal-processing algorithm to digitally process interference patterns and live-stream the 3D profile. This algorithm can be optimised for specific applications, achieving optimal performance in controlled environments with reduced noise and resolving signals down to 10 nanometres.
