Title: A Compact, Low Cost, Handheld Sensor for Non- Destructive Material Case Depth Verification
Agency: DOD
Contract: N68335-12-C-0001
Award Amount: $796,673.00


In this SBIR program, AlphaSense, Inc. teamed with the Center for Non-destructive Evaluations at Iowa State University to develop a compact, low cost handheld sensor for non-destructive material case depth verification. In phase I, we have proven the feasibility of using an alternating current potential drop (ACPD) sensor for non-destructive measurements of case depth. Phase II will be focusing on the optimization of the sensor system to improve its performance in terms of sensitivity, measurement accuracy and inspection time. Additionally, we will implement a compact, portable, relatively inexpensive and field testable prototype. Furthermore, we will develop methods to automatically extract the gear alloy type and case depths based on the measurement data.
