This Small Business Innovative Research Phase I project will demonstrate the feasibility of using a new type of adaptive receiver as part of a low-cost laser ultrasonic inspection system for manufacturing inspection and process control. Our goal is toproduce a very high detection sensitivity, while maintaining the capability to compensate for mechanical vibrations and atmospheric turbulence that ...

DESCRIPTION (provided by applicant): The long-term goal of this project is to create an efficient, unique, and versatile laser instrument that will have applications in a large range of surgical procedures including dermatology, laryngology, otology, and ophthalmology. In the near-term, these instruments will act as efficient replacements for Er:YAG and Er:YSGG lasers used in several dermatologica ...

To reduce weight and improve fuel efficiency, composites are being using in aircraft construction at an accelerating rate. The presence of material defects in these composite structures can lead to disastrous failure under flight loads. Many classes of these defective regions are undetectable by conventional NDI techniques such as ultrasonic probing. A revolutionary new inspection technology in ...

To reduce weight and improve fuel efficiency, bonded composites are being used in aircraft structures. Once a structure is assembled, there is no conventional NDI method available to assure that the strength of the bond is adequate for service. This program will develop processing heads and inspection techniques that will 1) allow the NDI of joints in remote locations accessible only through sma ...

DESCRIPTION provided by applicant The emerging light based imaging technique of acoustic resolution photoacoustic endomicroscopy AR PAEM enables visualization of subsurface tissues with microscopic resolution at depths of many millimeters AR PAEM images provide crucial information regarding microvasculature morphology and tissue physiology blood oxygenation For cancers originating in ...

DESCRIPTION (provided by applicant): Physical Sciences Inc. (PSI) proposes to develop a new adaptive optics imaging approach to high- speed 3D-retinal mapping with enhanced Fourier Domain Mode-locked (FDML) swept-source technology. PSI is currently engaged in ongoing development of high performance, high resolution multimodal adaptive optics (AO) retinal imagers. Such systems resolve and quant ...

PSI PROPOSES A PHASE I EFFORT TO DESIGN A CUSTOM SCANNING APPARATUS THAT, WHEN ASSEMBLED IN PHASE II, WILL INCREASE THE DATA DISPLAY RATE OF THE NOSC THREE-DIMENSIONAL VOLUMETRIC DISPLAY BY AT LEAST ONE ORDER OF MAGNITUDE ABOVE ITS CURRENT CAPABILITIES. IN ADDITION, THE APPRATUS WILL PROVIDE A MULTI-COLOR CAPABILITY TO THE CURRENT MONOCHROME DISPLAY. DISTINCT COLORS WOULD FACILITATE DISTINCTION OF ...

This SBIR Phase I proposal proposes to develop a versatile ballistic-proof laser eye protection (LEP) device which can be integrated with any currently fielded magnified optics (i.e., M145 MGO, M150 RCO, M151 SSS, etc.), and easily modifiable to integrate with future optical systems. The proposed device is made from a novel quasi-solid-state material composite consisting of micro-size liquid dropl ...

This proposal is to develop a non focal plane laser protection device for the Army and other DoD agencies. The device will be composed of single-crystal plates with hidden reflective/diffraction gratings, which can be revealed with exposure to strong pulsed or continuous laser, and a reversed-mode polymer-stabilized-cholesteric-texture (PSCT) light switch. This proposed device can change from a hi ...

IMPROVEMENTS OF LASER-HEATED THERMOLUMINESCENCE THAT ARE DESIGNED TO MAKE DOSIMETRY OF MIXED GAMMA-FAST NEUTRON FIELDS FEASIBLE WILL BE IMPLEMENTED AND TESTED. THESE ADVANCEMENTS IN LASER HEATING TECHNOLOGY ARE EXPECTED TO INCREASE THE FAST NEUTRON THERMOLUMINESCENCE SENSITIVITY SUFFICIENTLY TO MAKE TLD OF FAST NEUTRONS A CONVENIENT METHOD FOR ROUTINE PERSONNEL DOSIMETRY. THIN LAYER DOSEMETERS WIL ...
