*Tiny Lenses Capture Very Big View*
	Engineers from the University of Wisconsin-Madison have created the 
first-ever flexible, Fresnel zone plate microlenses with a wide field of 
view — a development that could allow everything from surgical scopes to 
security cameras to capture a broader perspective. The advance centers 
on a method for creating tiny lenses, each the size of a grain of salt, 
embedded within a flexible plastic polymer. This approach allowed the 
researchers to bend an array of multiple lenses into a cylindrical 
structure. An array of these miniscule lenses, each no larger than a 
head of a pin, can capture an almost complete panorama, producing images 
from a 170-degree field of view.

*New Electron Microscopy Method Sculpts 3-D Structures at Atomic Level*

	Electron microscopy researchers at the Department of Energy's Oak Ridge 
National Laboratory have developed a unique way to build 3-D structures 
with finely controlled shapes as small as one to two billionths of a 
meter. The new technique demonstrates how scanning transmission electron 
microscopes, normally used as imaging tools, are also capable of 
precision sculpting of nanometer- sized 3-D features in complex oxide 
materials. By offering single atomic plane precision, the new technique 
could find uses in fabricating structures for functional nanoscale 
devices such as microchips.

*Onion-Like Layers Help New Nanoparticle Glow*

	A new, onion-like nanoparticle could open new frontiers in bioimaging, 
solar energy harvesting and light-based security techniques. The 
particle's innovation lies in its layers: a coating of organic dye, a 
neodymium-containing shell, and a core that incorporates ytterbium and 
thulium. Together, these strata convert invisible near-infrared light to 
higher energy blue and UV light with record-high efficiency, a trick 
that could improve the performance of technologies ranging from 
deep-tissue imaging and light-induced therapy to security inks used for 
printing money.

	*Using Low Light Level CMOS Sensors to Augment Thermal IR Security and 
Surveillance Systems*

Sponsored by PHOTONIS

Available on Demand

Unfortunately, for security and surveillance applications, thermal 
cameras do not offer the insight that a visible day camera can provide. 
They also cannot provide complete scene understanding in situations such 
as thermal cross over times or when there is minimal 
target-to-background thermal differential. Learn how low light CMOS 
cameras can augment scene understanding and threat recognition to 
enhance critical recognition details.

	*High Performance, 1.5 µm, CW and Pulsed Fiber Lasers*

Sponsored by OFS

Available on Demand

In this Tech Talk we present recent results on high power continuous 
wave sources using Raman fiber lasers. Furthermore, high power, single 
mode Raman fiber lasers can be used as a pump source for Er-doped fiber 
amplifiers. Next generation fiber design together with Raman fiber laser 
pumping enables ultra-large area fiber lasers for all-fiber fusion 
spliced sources of high energy and high peak power pulses in the 1.5 
micron wavelength region.

	*Pleora Technologies* (Ottawa, Canada) has introduced an evaluation kit 
that helps manufacturers assess image sensor performance to speed the 
design of advanced medical and scientific imaging systems. The new kit 
provides a fully assembled sensor evaluation board based on Pleora's 
field-proven iPORT™ NTx-U3 Embedded Video Interface and the CMOSIS 
CSI2100 Image Sensor. By simply installing the supplied software, and 
connecting the evaluation board to a USB 3.0 port on a laptop or desktop 
PC, designers can perform image reconstruction, reformatting, and 
high-speed recording functions to assess image sensor performance.

	*Lumics GmbH* (Berlin, Germany) has developed a proprietary diode laser 
driver board that is optimized for the Lumics LuOcean™ "Mini" series. 
This brand-new driver board uses cooling by free convection only, and 
offers full digital access to all functions of the laser module. For 
customers in the medical field, diode protective features like automatic 
shut down in case of overheating or turning off the laser diode after 
error/interlock are crucial. Data read-out can be done via a standard 
RS232 programming interface. The associated LuOcean™ Mini modules cover 
wavelengths from 793 – 1940nm and offer power levels from 7W up to 70W 
out of fibers with 105 µm to 600 µm fiber core size.

	*LASER COMPONENTS* (Bedford, NH) provides everything needed for the 
input coupling of light using adjustable couplers to transmission via 
optical fiber assemblies to output coupling using focusable collimators. 
Input couplers are used to couple collimated light into an optical 
fiber. The inner optic can be adjusted along three axes to allow laser 
beams with Ø ≤ 10 mm to be focused on optical fibers with a core 
diameter between 100 µm and 2000 µm. The maximum power of the laser beam 
to be coupled is up to 150 W. For optimal power transmission, the optics 
are also coated; three wavelength ranges between 400 nm and 1300 nm are 
available.
