In the Phase I period, Sentient upgraded its DigitalClone for Additive Manufacturing (AM) technology and successfully demonstrated and validated its ldquo;Process modelrdquo; and ldquo;Microstructure modelrdquo; for simulating metal AM processes. Sentient has partnered with University of Nebraska ndash; Lincoln for model validation.Specifically, Sentient has implemented a new ldquo;Process modelrd ...

This proposal addresses, for the first time, the demonstration of integrated mid-infrared sources based on waveguiding in a bonded solid-state laser material and periodically poled nonlinear material. A focused femtosecond laser beam allows for precisely localized modification of the refractive index of a material, therefore enabling to create waveguiding structures. The offeror has demonstrated f ...

In Phase I, we have begun development of an advanced nanometer coordinate measuring machine (ANCMM; pronounced rsquo;a?-kem) to complement the metrology probe and complete the metrology solution.nbsp; The ANCMM will enable larger, lower cost, and higher quality freeform and aspheric optics, bridging the present gap between commercial coordinate measuring machines (CMMs) and interferometry, and, fo ...

The OptiPro Nanometric Probe is a spectral chromatic interferometer that can measure the displacement to a surface, such as an astronomical telescope mirror, with outstanding performance.nbsp; Indeed, in Phase I we designed and built a Probe that demonstrated 0.48nm repeatability (one sigma).nbsp; When scanned across the surface of the mirror a full topographical map of the surface ndash; and its ...

SeeQC is developing cryogenic multiplexing readout circuitry for superconducting sensor arrays. Our design and advanced multi-layer Niobium fabrication process enable us to make a compact SQUID based readout for large scale superconducting bolometer arrays.Arrays of superconducting transition edge sensors (TES) are frequently deployed in instruments for far infrared (IR) astronomy, particularly fo ...

Many new revolutionary concepts have emerged recently as viable pathways to invent next generation high performance structural components. With the emergence of additive manufacturing (AM) and its rapid advances for metals and alloys, practical realization of these concepts is imminent. However, the lack of microstructure-informed structural analysis and design tools is a critical gap in the field ...

This proposal innovates an ultrafast laser welding (UFLW) system and processes that provide epoxy-free bonding of optical and mechanical components suitable for lidar sources in the space environment. This proposal responds to SBIR subtopic S1.01 Lidar Remote Sensing Technologies, aiming at improving instrumentsrsquo; compactness, reliability, lifetime, and long-term performance. It will develop t ...

Safe airspace and operations depend on accurate weather data to make critical decisions, plan fleet asset taskings, schedule cargo or people movements, and meet client expectations.nbsp; More reliance on automation means there are less nodes in the workflow where humans can identify anomalies in data.ResilienX is proposing to develop a Weather Sensor and Data Monitor (WSDM) service that we will in ...

C-C material systems have high strength:weight ratios at high temperatures, making them well suited for future hot structure designs.nbsp; However legacy C-C solutions are subject to poor through thickness propertiesnbsp;(for 2D laminates), or manufacturing speed and capacity issuesnbsp;(for Cartesian billets.)nbsp; These issues are often compounded for tubular or conical geometries.nbsp;nbsp;nbsp ...

Several presentations were given at NASArsquo;s 2019 Mirror Tech Days that highlighted the shortcomings of current mirror-fabrication technologies, particularly as they relate to demanding missions such as LUVOIR and HabEx.nbsp; Many of the mirror deficiencies, such as areal density, surface figure error, stiffness, and surface figure changes over temperature, can be traced ndash; either directly ...
