FIGURE 1. The transparent zebrafish embryo enables paired patch clamp measurements of spinal neurons and locomotory muscle cells. Two chevron-shaped repetitive segments of tail muscle are shown. The two patch clamp recording electrodes are shown for an individual motoneuron and muscle cell. Only one electrode is visible in the field because placement of the electrodes during formation of whole-cell recording mode is done under very high magnification.

A diagram shows NIST’s ion trap used for reversible “quantum squeezing” to amplify and measure ion motion. The ion (white ball) is confined 30 microns above the trap surface by voltages applied to the eight gold electrodes and the two red electrodes. Squeezing--that reduces the uncertainty of motion measurements--is achieved by applying a specific signal to the red electrodes. The ion is moved by applying another type of signal to one of the gold electrodes. Then the squeezing is reversed, and the blue electrodes generate magnetic fields used to decode the amplified motion measurements.

LASER World of PHOTONICS 2019: Inspiring

The depth and diversity of photonics technologies and products on display is an exciting reminder of the pivotal role of the world’s leading photonics tradeshow.

$A nonperiodic pinhole-based photon sieve widens the display angle of a lensless digital dynamic holographic display produced by a liquid-crystal-based spatial light modulator (SLM). At top, a dynamic holographic display without the nonperiodic photon sieve has a narrow viewing angle. At bottom, a holographic display with the nonperiodic photon sieve, which diffracts light at a high angle, has a larger viewing angle. The pinhole array in the sieve is made nonperiodic to avoid creating periodic arrays of diffraction artifacts. The researchers note that the holographic objects to be displayed need to appear within the shaded regions to prevent clipping.$

Large-scale simulations demonstrate that chaos is responsible for stochastic heating of dense plasma by intense laser energy. This image shows a snapshot of electron distribution phase space (position/momentum) from the dense plasma taken from PIC simulations, illustrating the so-called 'stretching and folding' mechanism responsible for the emergence of chaos in physical systems.
