A UNIVERSAL ELECTRICAL ILLUMINATOR.

Darkfield Micromanipulation with an Ultropaque Illuminator Recently

second. The other ciliates studied obviously have a much lower speed of coordinating impulse. These values are so far below the velocities of true neural impulses that it is not possible to consider a "neuromotor" factor in the coordination of these Protozoa. Further investigations are in progress along the lines indicated here and will be reported in detail. The writer is indebted to Dr. W. M....

A Broadband Laser Illuminator for Active Hyperspectral Imaging

We have been investigating the use of supercontinuum (SC) laser technology to provide active illumination for shortwave infrared (SWIR) hyperspectral sensors in order to extend their operational window into the night and heavy overcast periods. Unlike a lamp, light from a broadband laser illuminator (BLI) can propagate long distances through the atmosphere while maintaining its spatial coherenc...

Interferometric array illuminator using polarized beams

A two -dimensional non-observable square array illuminator using four polarized beams from two interferometers in tandem is reported. The array pattern could be scanned over large longitudinal distances without loss of distortion. Fringe visibility of interferograms has been studied as a function of polarization of the interfering beams. The expressions for the array patterns and the fringe vis...

A Universal Newborn Hearing Screening in Iran

Objectives: In September 2002 University of Social Welfare & Rehabilitation Sciences established a pilot universal newborn hearing screening program in two crowded maternity hospital in Tehran. Our objective was to assess the feasibility of implementing universal newborn hearing screening in IRAN. Methods: Between September 2002 and March 2004 a total of 7718 newborns were screened for heari...
