Microwave Inspection Nondestructive Imaging Array

Completed Technology Project

Project Description

Microwave Inspection Nondestructive Imaging Array, Phase I
To address the NASA need for advanced NDE sensor technologies for structural materials, Physical Optics Corporation (POC) proposes to develop a new Microwave Inspection Nondestructive IMaging Array (MINIMA), based on the novel integration of new compact near-field microwave imaging and optical sensors and comprehensive control and analysis software. The fusion of microwave and optical sensors provides a new capability to identify surface locations for further inspection and carry out those inspections with the ability to see through nonconducting parts. The highly integrated system design utilizes onboard position tracking and imaging sensors to track, register, and overlay microwave sensor data and optical imagery to precisely pinpoint defect data with respect to the actual part location and even other mechanical CAD models. In Phase I, POC plans to design the MINIMA system, define subsystem requirements, and develop algorithms for data fusion and registration based on modeling and simulation. We will assemble, test, and demonstrate a proof-of-concept prototype in a laboratory environment and include a short description for Phase II prototype. In Phase II, POC will refine the MINIMA design and develop an improved prototype for testing. We will develop full reports of development and test results along with a plan for applying the prototype to applicable structures. More »
