Each month, NTB highlights tech briefs related to a particular area of technology in a special section known as Technology Focus. Here's an Insider look at the April focus on Sensors. Wearable Environmental and Physiological Sensing Unit Developed at NASA™s Ames Research Center, the wearable environmental and physiological sensing unit (WEPS) is a prototype of systems to be worn by emergency workers to increase their level of safety. The WEPS includes sensors that measure a few key physiological and environmental parameters, a microcontroller unit that processes the digitized outputs of the sensors, and a radio transmitter that sends the processed sensor signals to a computer in a mobile command center.

High Performance Multi-Sensor for Non-Stop Biological Monitoring A Fiber Optic-Based Integration System (FOBIS) has been developed that may be capable of in-situ, real-time biological monitoring, and is based on a single fiber optic system. A compact, multi-functional device, the FOBIS incorporates three working units (a Micro-Flow Cytometer, a Micro-Photometer, and a Micro-Sensor) into a compact, space-worthy package with small, low-cost, rugged packaging and field applicability.

Filter Function for Wavefront Sensing Over a Field of View

Optical performance is more balanced when data from more field points are used. A filter function has been derived as a means of optimally weighting the wavefront estimates obtained in image-based phase retrieval performed at multiple points distributed over the field of view of a telescope or other optical system. When the data obtained in wavefront sensing and, more specifically, image-based phase retrieval, are used for controlling the shape of a deformable mirror or other optic used to correct the wavefront, the control law obtained by use of the filter function gives a more balanced optical performance over the field of view than does a wavefront- control law obtained by use of a wavefront estimate obtained from a single point in the field of view. (The terms “wavefront sensing,” “image-based,” and “phase retrieval” are defined in the immediately preceding article.)
