Laser rangefinders have numerous NASA and non-NASA applications, including navigation, landing hazard avoidance, automated rendezvous and docking, air and missile defense, infantry and artillery target designating, tank and infantry fighting vehicle fire controlling, surveillance through foliage, cloud-height measurement, and production monitoring in industries as well as commercial and law enforcement, etc. Existing laser rangefinders cannot meet some of the advanced performance requirements including wide field of view (FOV) for situation awareness, high angular resolution for detailed target shape discrimination, and fast response for transit event or moving objects tracking, as well as low weight, volume and power requirements, etc. For NASA's lunar exploration missions, lunar roving vehicle with features of automated path planning, automated driving, and obstacle avoidance are of interest for making planetary surface missions more reliable, safer, and affordable. New Span Opto-Technology Inc. proposes herein a novel laser rangefinder architecture with non-mechanical scanning foveal aperture providing wide FOV 3-D scene profile for situation awareness and high resolution 3-D profile of region of interest for object tracking. System packaging is rugged, compact and light-weight. Phase I research will establish the model, demonstrate the feasibility, and recognize challenging issues of the proposed concept through model analysis and bench top experiments.

Mapping awareness of battlefield is increasingly valuable for many military mission planning and activities, particularly in complex urban and mountainous terrain. Currently available two-dimensional (2D) visualization techniques have limit capacity to achieve understanding of full dimensionality of the battlefield. Rewritable 3D holographic storage is promising for updatable 3D display applications. Based on our encouraging preliminary study on reversible nonvolatile holographic storage, New Span Opto-Technology Inc. proposes herein a novel large-area 3D updateable holographic display (UHD), capable of reversible recording and nonvolatile reading based on a novel bi-photonic holographic technique without using high-voltage electrical field across the polymer film. The proposed technique exploits one laser source for both coherent recording and reading processes. The Phase I research will focus on feasibility studies of the proposed UHD concept by recording reversible holograms and reading the stored information without volatility using azobenzene photorefractive polymer films. In Phase II, we will improve the system design and construct and characterize a 300 x 300 mm prototype true 3-D display system. We will study the functionality of the prototype system through demonstration of high diffraction efficiencies, wide viewing angles, fast writing times, long persistence of hours or more, controllable erasure with thousands write/rewrite cycle capability.

Multispectral imaging sensors are needed to identify activities and connections associated with proliferation of weapons of mass destruction. Electronically tunable optical filters enable multispectral imaging with no moving parts. However, for some applications such as transient events or moving targets, current filters do not provide sufficiently fast response time, high throughput, large aperture, and wide spectral coverage. This project will develop a multispectral imaging sensor that is capable of dynamically random access of spectral center and flexible setting of spectral bandwidth. Using a fast spatial modulating device, a fast transition time between spectral channels can be achieved. With the proposed architecture, it will be inherently easy to realize sensors of large aperture, high throughput, and wide spectral range. Phase I will conduct technical analysis and design, and construct a preliminary bench-top experimental setup to demonstrate critical technologies and the feasibility of the proposed concept. Commercial Applications and other Benefits as described by the awardee: The spectrally-agile multispectral imaging sensor should find military applications in urban warfare, threat analysis, land mine detection, chemical analysis, monitoring of terrestrial and atmospheric conditions, and the discrimination between manmade and naturally occurring materials. Commercial applications should arise in precision farming (monitoring crop yields, health, disease management, irrigation); the marine and coastal environment (phytoplankton detection, coastal mapping, ocean color, river deltas, iceberg tracking); natural hazard and pollution monitoring (oil spills, floods, forest fires, volcanoes); oil, gas, and mineral exploration (collection of geologic and structural terrain information, assist in planning field work); medical diagnostics such as photodynamic therapy; and spectroscopic medical image processing.

To address the U.S. Navy¡¦s solicitation for shipboard compliant high energy storage system, New Span Opto-Technology Inc. proposes to develop Advanced Hybrid Electrochemical Energy Storage (AESES) technology. The AESES is comprised of a foamed aluminum oxide ceramics anode and a conductive polymer cathode. The anode is made highly porous for higher capacitance. The cathode is made of an aligned pattern of polyaniline nanofiber arrays covalently bonded with the substrate, with high current and ion conductivity and lower internal resistance, resulting in high energy and power density of AESES. The device is engineered with an operation potential of 20-60 Volts and a total capacitance of 5-20 Farads. The AESES will have energy density ƒ® 150 Wh/Liter (~24J/cm3), power density up to 2,000 W/Liter lasting ƒ® 5 min, cycling life ƒ® 10,000 times, at environmental temperature up to 150 F (60 ¢XC). In Phase I we will demonstrate the feasibility of the AESES concept by fabricating a prototype module, capable of being incorporated into a power electronics and ship interface module. The comprehensive performance of the AESES module will be evaluated. The Phase II development approach and schedule that contains discrete milestones for product development will be provided.

Wide field-of-view imaging sensors with high spatial and spectral resolution ability have extensive applications in military and commercial fields. Current methodology of employing FLIR or video imaging sensors to search and acquire potential targets is time consuming since the operator must continuously scan the area of interest in a wide view field and zoom in a local area to acquire the target details. The format size of existing imaging arrays cannot support high-resolution imaging and wide field-of-view simultaneously. Furthermore, spectral information is also significant for applications such as spectral discrimination in target identification, camouflage detection, and environmental monitoring. Several prototype hyperspectral systems have been produced, each with its own strengths and weaknesses. There is a demand to develop an electronically controlled spectral- and spatial-foveated multi/hyperspectral sensor that is dynamically programmable to achieve variable spectral/spatial resolution in user defined regions of the image. New Span Opto-Technology Inc. proposes herein a compact optical configuration that is capable of simultaneously providing panoramic monitoring and high spatial and spectral resolution in areas of interest without mechanical scanning to facilitate instant hyperspectral imaging for improved surveillance and identification capability. Phase I will establish the model and demonstrate the feasibility of the proposed architecture.
