Researchers at Penn State are developing a new type of imaging that does not require a lens and uses reconfigurable particle-based masks to take multiple shots of an object. The technology i...
“A picture is worth a thousand words”: a famous quote about knowledge dissemination but also literally true. The documentation of cultural heritage (CH) monuments is carried out by measurements and ph...
Immersive technologies like Virtual or Augmented Reality (VR/AR) are lately becoming more and more popular in wide range of scientific applications. These technologies provide the most immersive way t...
Imagine a hand-held environmental sensor that can instantly test water for lead, E. coli, and pesticides all at the same time, or a biosensor that can perform a complete blood workup from just a singl...
Ge/Si avalanche photodiodes with record high gain-bandwidth and sensitivity for communication wavelength and high data rate, 10Gbps and 40Gbps, is demonstrated. These devices can be monolithically int...
Digital Cinema is a promising application that utilizes high-speed optical networks to transfer super high definition images. The networks are primary used for distributing packet data of digital cine...
A series of novel wide range displacement sensors based on polarized light detecting technology is presented. The sensors include a displacement-current comparator and a servo comparison displacemen...
Using newly developed PLZT-based OBS core node, low-loss Ether-frame transmission with application-layer connectivity is demonstrated over 92-km 2-hop field testbed. Recent progresses in developing OP...
By observation of cicada ovipositor’s movement, we found that tensile strength and hardness of sheath material are effective against cicada attack.. And also, we have newly designed the optical drop c...
We report the 1.27 μm AlInAs APD with high responsivity of 0.93 A/W and wide bandwidth of 8.3 GHz at a multiplication factor of 10 optimized for 10G-EPON (OLT).
A review is made of the principle and recent development of free-electron lasers (FELs) with emphasis on applications in the infrared wavelength region. Technologies of FEL generation have become matu...
The hadronic cancer therapy is more attractive than the surgery for localized tumor. However, the hadronic radiotherapy seems not to be easily spread out, because it needs huge capital investments as ...
The hybrid hologram screen, or HHS for short, is a system that enables the display of auto-stereoscopic images. Two of its main advantages are that the size of the view zone can be controlled, and tha...
A practical OCT imaging system for ophthalmology became commercially available only five years after the first demonstration of OCT. OCT is thus an epoch-making technique in optics. In such developmen...
High performance laser welding process for thick materials was developed under the photon national project. In the heavy industries thick materials were required to weld with high quality without weld...
