Hyperspectral Imaging Shines Light on Ancient Mexican Text
Researchers at the Bodleian Libraries have used hyperspectral imaging to reveal never-before-seen pictographic scenes from a rare precolonial Mexican codex that has been hidden underneath a layer of gypsum and chalk for 500 years. Until now, no other technique has been able to unveil the concealed pictorial narrative in a noninvasive manner.

Direct-Drive Laser Fusion Experiments Move Toward Target Ignition
Conditions capable of producing a direct drive laser fusion yield that is five times higher than the current record for laser fusion energy yield have been demonstrated. The work, which shows the use of direct-drive laser fusion to compress fuel to about half the pressure required to ignite it, represents an advance in a national research initiative to develop fusion as an energy source.

Ultrahigh-Resolution Microscope Images Whole Cells in 3D
A novel superresolution nanoscope allows 3D imaging of an entire mammalian cell and its cellular constituents at a resolution that is 20 to 50 times higher than conventional microscopy, with imaging depth improved approximately tenfold over state-of-the-art iPALM and 4Pi-SMSN implementations. Until now, resolving details at this level was only possible using electron microscopy, which requires samples to be treated.

Laser Identifies Size, Shape of Materials for Quicker Optical Design
When optical diffraction was used to analyze the structure of a photonic crystal, researchers found that it created a characteristic light pattern that corresponded exactly to the number of scattering microscopic particles in the sample. The ability to determine the precise number of scatterings in optical materials has previously been done using electron or atomic-force microscopy only. A novel method for determining the properties of optical materials, done without the use of expensive microscopy tools, could help speed the design of optical devices.

Laser Measurement Best Practices: How to Avoid Choosing the Wrong Power/Energy Sensor
Tue, Sep 27, 2016 1:00 PM - 2:00 PM EDT
Sensors are critical for accurate laser measurement, yet they are often selected based on the wrong criteria. In this webinar, Ophir-Spiricon sales engineer Dick Rieley will discuss laser measurement best practices and will guide you through key factors in the sensor selection process, including beam diameter, beam density values, cooling requirements, and exposure duration. Choosing the wrong laser sensor can result in a damaged sensor and invalid measurements of the laser’s performance. Join us for this free webinar on sensor selection, to be sure that you make the right choice.
