Luna Technologies' Optical Distributed Sensor Interrogator, ODiSI, is a new sensing product capable of providing fully distributed temperature and strain measurements data by using optical fiber as a continuous sensor. The ODiSI gathers data along the entire surface and allows the user to redefine the sensing point post processing. These features, not available with traditional static point sensors, provide advantages to industries where precise temperature and strain measurements are necessary for structural or mechanical testing.

Fiber optic sensor technology now provides more insight into the performance, tolerances, and failure mechanisms of structures and vehicles and is being used more widely as demands for lighter, stronger, and safer structures continues to grow.

Designed with the most advanced fiber optic sensing technology, Luna's revolutionary ODiSI (Optical Distributed Sensor Interrogator) provides industries such as aerospace, automotive, energy, and other composites industries a sensing solution that is rich in data, lightweight, robust, easy to install, and does not require expensive Fiber Bragg grating fiber.

"We are very excited about the announcement of our new sensing product," said Luna's CEO, My Chung. "We believe the ODiSI will raise the bar for test and measurement standards across multiple industries and enable our customers to optimize mechanical designs, decrease maintenance, and deliver next generation products."
