Aspen Systems proposes a novel highly sensitive imaging and visualizing detector of eye-safe coherent Middle Infrared (MIR) Radiation (2 - 5 microns). The detector can operate at room temperature with noise-equivalent power NEP < 10 {super -12} WHz (super -1/2}, response time tau < 2.0X10 {super -7} s and an active aperture of few square centimeters. In the detector, the middle infrared images a ...

Aspen Systems proposes to develop a Er+3:Yb+3 doped double clad fiber laser amplifier with an output power of 10 W. The active core enclosed by a large rectangular inner cladding is end pumped with a beam from a laser diode array delivered by a bundle of rectangular core fibers preserving the brightness. This active fiber is periodically re-charged, using efficient side couplers, with a system o ...

Aspen System proposes an innovative technology for correcting the phase of a high power laser beam delivered via a multimode fiberoptic. The proposed system has an architecture lending itself to a broad variety of applications that range from ladars to medical catheters. Keeping the commercial applications in perspective, the laser source and other bulky components are positioned at the back-e ...

Various diesel reforming methods have been tried to develop an efficient and reliable means of providing hydrogen to fuel cell power systems promising high efficiency and low pollution. The most difficult obstacle has been coking up of reformers. Aspen proposes to solve the coking problem through an approach based on two proprietary technologies: catalytic diesel cracking and hydrogen separati ...

To meet the challenge of impermeable barrier coatings for honeycomb composite structures, Aspen Systems, Inc. proposes the program "Novel Liquid Crystal Thermosets for Barrier Coating Binder Matrices". Designed from the molecular level, these new materials are based on room temperature, solventless processable, orderable, low molecular weight, liquid crystalline (mesophasic) structures with flexi ...

Aspen Systems proposes to develop a multichannel, bidirectional, off-axis optical slip ring connector capable of establishing communication between two rotating surfaces. The novel design utilizes commercial off-the-shelf components providing high bandwidth (THz) with enhanced sensitivity and improved reliability. Since data transmission across the rotating interface is performed in free space t ...

Aspen Systems proposes to develop a novel process to increase the strength of sapphire at elevated temperatures. The resulting increase will alleviate strength losses in high performance IR seeker systems such as THAAD and Standard Block IV. The Aspen process will uniformly implant silicon atoms within the sapphire window material. This will in turn pin the crystal lattice resulting in a structure ...

The intent of this program is to develop workable concepts that will result in commercial and military high performance, covert, low cost, adaptable antennas in gain, coverage, and a variety of equipment applicability for hand held use. Ideally, the program will result in a technology capable of significantly foreshortening antennas (4:1) while maintaining low losses, hemispheric coverage, novel ...

The program objective is to develop novel designs, techniques, and structures to synthesize apertures capable of efficient operation over broad frequency ranges and functions. Conventional apertures are narrowly focused, application specific, and basically single point design. To decrease the cost of antennas, a more universal building block design is required. It would provide a significantly ...

The overall goal of the proposed effort is to develop a fusion process that integrates SAR and hyperspectral sensor data in order to overcome the current performance limitations of single sensor automatic target cueing. In the Phase I effort, we will define a concept of operation for SAR/hyperspectral automatic target cueing. The nature of the imaging domains of SAR and HS sensor as well as the ...
