Technology research and development in such areas as next-generation atomic clocks, quantum information processing with trapped ions, and atomic spectroscopy is impeded by the lack of commercially available laser sources that meet the required specifications of wavelength tuning range, output power, frequency-stability and reliability. Arete Associates is developing frequency-stable Optically Pump ...

The characterization of biologically relevant polymetric materials is a major focus of the bioinstrumentation industry. Of particular interest is the rapid, direct sequencing of DNA through a nanopore as well as the characterization of other biopolymers. Although progress has been made with nanopore sequencing, some fundamental instrumental and system issues have so far kept the method from realiz ...

In recent years, there has been increasing concern about the role of man-made sound on the marine environment. For this effort, we propose developing an intuitive software interface for sound propagation modeling. This will be based on software developed at HLS Research, Inc. for similar applications. The software will use existing propagation modeling codes that have a long history in the unde ...

There is a need to advance the state of the art low power, portable autonomous underwater hydrophones for recording fish spawning calls and other marine acoustics. Affordable and reliable autonomous underwater vehicle (AUV) mountable hydrophones that can detect such signals in the presence of AUV motor noise are required. A system that includes software to automatically determine fish size, type ...

During the Phase I SBIR project Optical Physics Company (OPC) investigated a three axis interferometer instrument which measures the one dimensional linear translation and the two-dimensional angular deflection in pitch and yaw of a 7 mm mirror 18-23 cm away. Lab demonstrations both before and during the Phase I effort showed performance parameters better than NIST requirements. The Phase I effort ...

The SeaTagTM project proceeds in Phase II to implement and test a family of micro observation stations that go beyond the concepts of traditional electronic data logging animal tags. These will include functions such as communication between SeaTagTM devices to obtain data from many animals when one tag is recovered or transmits. Deployment methods are extended to mounting on predators to monito ...

Laser Technology Inc. (LTI) proposes a Phase II SBIR research project to further develop a Compact Shearography System, Analysis Method and Software for micro-crack detection in concrete. There is an urgent need to detect and characterize fine cracks in concrete that form because of various damage mechanisms including alkali-silicate reaction, delayed ettringite formation or frost damage. Fine s ...

Development of the basic EMAT based transverse rail defect detector has progressed toward finished form, as envisioned in the original solicitation. This modification is intended to produce a demonstratable version of a 2-rail detection system with automated signal interpertation. The objectives of this work are to: a. Further develop the system into a functioning 2-rail detection system, as ori ...
