Top 5 Best Uses and Benefits of OCR Technology
Technology is one of the important factors, which shapes rapidly changing digital environment as it changes many aspects of our life. One technology that revolutionized the field of human-textual interaction is optical character recognition (OCR). OC.....»»
A "quantum leap" at room temperature: Ultra-low noise system achieves optical squeezing
In the realm of quantum mechanics, the ability to observe and control quantum phenomena at room temperature has long been elusive, especially on a large or "macroscopic" scale. Traditionally, such observations have been confined to environments near.....»»
Synthetic fibers and tire abrasion found to have the strongest impact on corals
Corals feed on plankton that they catch from the seawater. Due to the increasing pollution of the oceans, they also ingest tiny plastic particles. Sometimes, the corals are unable to expel the microplastics from their bodies. Instead, they store it i.....»»
A new optical metamaterial makes true one-way glass possible
A new approach has allowed researchers at Aalto University to create a kind of metamaterial that has so far been beyond the reach of existing technologies. Unlike natural materials, metamaterials and metasurfaces can be tailored to have specific elec.....»»
New research reveals mechanisms of stiffening in paper pulp, could lead to improved recyclability
One of the problems with paper recycling is that the fibers stiffen during the dewatering and drying processes, also known as hornification. The same thing happens to dishcloths, for example; they stiffen over time. New research can now explain the m.....»»
New InP-based modulator with record-high bit rates could help move more data faster
As data traffic continues to increase, there is a critical need for miniaturized optical transmitters and receivers that operate with high-order multi-level modulation formats and faster data transmission rates......»»
Optical invention mirrors the image processing power of a human eye
On a cold, sunny day, you're driving on a rural road, surrounded by snow-covered fields. In an instant, your eyes process the scene, picking out individual objects to focus on—a stop sign, a barn—while the rest of the scene blurs in the periphery.....»»
When nanoplastics are not what they seem: Release of oligomers from polyester textiles
Plastic household items and clothing made of synthetic fibers release microplastics, particles less than five millimeters in size that can enter the environment unnoticed. A small proportion of these particles are so small that they are measured in n.....»»
Submonolayer biolasers: Lower gain, higher sensitivity
Designing sensitive and single-use biosensors for early diagnosis remains a major challenge. Scientists in China have invented submonolayer lasers on optical fibers as ultrasensitive and disposable biosensors......»»
Multi-dimensional multiplexing optical secret-sharing framework with cascaded liquid crystal holograms
Information security has become particularly crucial under the background of the big data era. Optical secret-sharing schemes encrypt information and physically divide it into different shares. Information can only be decrypted by cascading a suffici.....»»
New E. coli strain will accelerate evolution of the genes of your choice
Strain eliminates the trade-offs of a high mutation rate. Enlarge (credit: Rodolfo Parulan Jr.) Genetic mutations are essential for innovation and evolution, yet too many—or the wrong ones—can be fatal. So researcher.....»»
Progress on chip-based spontaneous four-wave mixing quantum light sources
