The proposed effort is to build a high resolution, high speed spatial light modulator (SLM) to be used in infrared (IR) spectral projectors. An IR spectral projector produces programmable spectra by dispersing light onto a programmable array, currently digital micromirror devices (DMDs), which either transmit or block selected components of the light. the light is then recombined to form complex s ...

Two, complementary techniques are proposed that are deployable on dropsondes or mobile measurement platforms and measure the scattering coefficient of atmosphere aerosols. The Phase I activity will be a proof of concept study that evaluates the relative strengths and weaknesses of the two measurement systems and combines a detailed analysis of the optical and electronic systems with a laboratory ...

New innovative technology for the visually impaired has been developed by NIST. If commercialized, it would provide refreshable tactile graphical information to the visually impaired, enabling them to compete on a more equal footing in the workplace and the education system.

A novel chemical vapor deposition (CVD) based step-flow epitaxy process is proposed for controllable growth of SiC nanowires with high polytype integrity. SiC nanowires will be grown in a modified commercial high-temperature CVD reactor, used by industry for growing high-quality SiC epitaxial thin films. Different polytypes of SiC nanowires will be grown by choosing appropriate substrate materials ...

Identify and study candidate architectures for supporting and cooling massive (~5 Kg) arrays of transition edge sensors, achieving hold times for one week at temperatures below 100mK.

Giant Grouper (E. lanceolatus) is one of the most desirable marine fish in the world. Its robust nature, tremendous growth rate, superb quality flesh and high value make it ideal for open ocean aquaculture. Phase I research marked the first time this species has been reared in the hatchery outside of Southeast Asia. Broodstock nutrition, spawning seasonality and lunar periodicity were defined. ...

The work proposed will provide a demonstration of feasibility and specific design recommendations for building an elevated-temperature resonating crystal balance with nanogram sensitivity. The approach will build upon existing technology commercialized by Masscal for operating a QCM in a temperature-controlled calorimeter. Precise temperature control and new types of crystal sensors will be used t ...

This proposal introduces the Detecting Intrusion from Network Anomalies (DINA) system, which uses data mining tools to automatically detect anomalous behaviors that can be related to undesired intrusion and/or attacks upon computer networks, as well as other use patterns which may indicate behaviors which are non-hostile but still problematic. The application will make use of Ensembles of Decision ...

The 1588 Precision Time Protocol (PTP) protocol has significant advantages for relative time synchronization on wireless networks.

VIPA etalons are simple, compact devices that offer many times more dispersion than gratings and are finding increasing application where higher spectral resolution is needed. Current VIPA fabrication methods limit efficiency, spectral resolution, filter response, and spectral bandwidth. Precision Photonics proposes to use its enhanced optical fabrication capabilities to build advanced VIPA protot ...
