Super-resolution Optical Imaging

VALUE PROPOSITION Conventional microscopes rely on making a spatial measurement of light, which are diffraction limited. Traditional scanning microscopy approaches obtain a spatial image by scanning across known locations. The wavelength of light becomes the limiting factor in achieving better spatial resolution. It would be advantageous to have a...

A Gating Grid Driver for Time Projection Chamber

Executive SummaryTime Projection Chambers (TPCs) are uniquely useful in analyzing nuclear reactions and resulting particles. These devices rely on fast gating systems to allow or deny entry of particles into the detection area; without which they would not be functional. MSU researchers have developed a novel gating grid driver system for TPCs. Due...

Ultrafast Square Pulses

Executive SummaryIt is desirable in many applications to precisely control the output pulse shape for high speed and high power laser systems. A flat top, fist rise and fast fall pulse is a desired pulse shape. In the case of a bandwidth-limited Gaussian pulse, the peak of the pulse is near the threshold but the rest of the pulse is well below the...
