The camera does not need a lens

01.02.2014

Rambus specialists have developed a CMOS image sensor that allows you to make cameras without lenses. As stated, the development will significantly reduce the cost and reduce the size of digital cameras by eliminating the lens, which accounts for a significant part of the cost and size.

In short, the new structure allows the main functions of the camera to be realized only by the sensor and the signal processor. To do this, a CMOS type sensor is endowed with certain optical properties. Note that the theoretical part of the study has already been confirmed by practice.

It is expected that reducing the cost and size of digital cameras will significantly expand their distribution. In particular, it will be possible to produce and use disposable cameras.

The developers note that new cameras need a rather complex signal processing scheme. In some cases, for example, for real-time video processing, the performance of this scheme must be relatively high. However, Rambus believes there are a number of applications where the benefit of eliminating optical components outweighs this overhead. In addition, the company estimates that the annual rate of growth in the specific performance of signal processing circuits is 150%, which is incomparably higher than the indicator of optical components, equal to 5%.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Miniature internal combustion engine 18.01.2002

A group of engineers from the Massachusetts Institute of Technology (USA), together with specialists from other universities and companies, is developing a miniature internal combustion engine that can replace batteries and accumulators in the future.

The dime-sized engine operates on the principle of a gas turbine driven by a stream of hot gases. It is capable of generating 20 W of power at a rotor speed of 2,4 million rpm. All the tiny components are made in the same way as computer components, and their production will not require large expenses. When developing the engine, the creators had to overcome numerous technical difficulties associated with the need to ensure acceptable (micron) surface accuracy, as well as the problem of removing a large amount of heat generated by the engine.

The developers are confident that a workable miniature engine will be assembled in two years, but commercial models will appear no earlier than 2010.
