Hyperspectral
Imaging System Through Holographic Polymer Dispersed Liquid Crystals (H-PDLC)
Switchable Filters
The ability to capture visual data at a high-fidelity rate along the electromagnetic spectrum, and interpret it, is an emerging technology known as Hyperspectral imaging; this technology allows us to understand our world at a deeper level. Using Holographic Polymer-Dispersed Liquid Crystals (H-PDLC) filters mounted onto a camera, an enhanced vision system can be created to analyze data in a broader range than just the visible spectrum, reaching into both the infrared and ultraviolet light. The use of expanded vision can be integrated into industries such as environmental monitoring, biotechnology, machine vision, and much more. For example, forest fires have managed to cause irreversible damage in many parts of the world. Through an advanced hyperspectral image system, specialists can capture images in the infrared to detect the heart of these fires to best attack it, and due to the physical properties of liquid crystals, the filters can be switched off instantly to capture images in the visible spectrum at the same instance. The capability to create an advanced imaging system allows for more data to be collected to help make more effective decisions in fields such as vision-systems, autonomous vehicles, and crop production.
