Development of the Interferometric Refractive Index Sensor (IRIS) data acquisition subsystem.
Laser atmospheric propagation performance is a function of optical turbulence. The Interferometric Refractive Index Sensor (IRIS) is a nodal instrument that directly measures the refractive index structure parameter of air in the local surrounding volume. The prototype IRIS design consists of two identical Michelson interferometer optical trains that are spaced ten inches apart and share a common laser source. This instrument is in development to provide near-real-time remote monitoring on optical turbulence in operationally relevant environments. Presented here is an overview of the current hardware and software design for the data acquisition subsystem in collaboration with Space and Missile Defense Test Center (SMDTC), University of Alabama Huntsville (UAH) and the High Energy Laser Measurement Support (HELMS) laboratory. The data acquisition hardware features a compact-portable design, and the software user interface is coded to collect and process data with low-latency.
