A compact, reliable, efficient and inexpensive cryocooler requiring less than 1 kW of power for 2W of cooling at 10 Kelvin is being developed and will be demonstrated. This performance is at least twice as efficient as the best current state-of-the-artfor small low-temperature cryocoolers. The proposed technical approach, whose technical feasibility and suitability for space-based applications h ...

This SBIR effort will develop advanced mode-matching structures for highly efficient electro-optic amplitude modulators in potassium titanyl phosphate (KTP). The intended application for these modulators is in intra-satellite fiber-optic data buses andother satellite communication and data-handling systems. The overall goal of this effort is the fabrication of electro-optic modulators featuring l ...

This program addresses a revolutionary low cost manufacturing technology of digitally switchable fiberoptic true time delay manifold for high performance phased array antenna. By using an improved electro-optic material system, the proposed integrateddevice will provide sub-microsecond high reconfigurable speed. Our approach is sate-of-the-art in design and closely coupled with proven volume fi ...

X-ray imaging is an important technique which is used in variety of applications such as nondestructive evaluation, radiology in medicine, astronomical observations, X-ray diffraction for materials studies, and others. The ability of X-rays to penetratedeep in to matter allows investigation of interior components with possibility of real-time dynamic studies. However, while significant advances ha ...

Target discrimination is one of the critical components of the midcourse phase processing in providing effective missile defense. Currently, detailed models that use an elaborate discrete Bayesian network predict the sensor phenomenology for each possibletarget type and sensor. The predicted sensor phenomenology is compared to the observed phenomenology, and the target type estimate is updated. ...

With the appropriate processing algorithms, surface-based radar has the potential to discriminate reentry vehicles from other threat objects in the presence of clutter, which is a critical part of the BMD problem. Discrimination is based on resolving theobjects in range, and characterizing each object's shape and motion. The algorithm we propose is the model-based approach, which applies a hypot ...

Quantum mechanics predicts that quantum two-level systems - qubits - can provide fundamentally new modes of information processing due to possible existing in an arbitrary coherent superposition of quantum states. A practical realization of quantuminformation processing requires obviously isolated quantum systems that act as qubits.ALTAIR Center proposed a novel practically realizable physical sy ...
