can you tell me something new happened in optics area recently?
Sure, here are a few recent developments in optics:
1. Researchers at the University of Rochester have developed a new type of lens that is flat, lightweight, and able to focus light with high efficiency. This technology could potentially replace bulky traditional lenses in a variety of applications, such as cameras and telescopes.
2. Scientists at MIT have created a new type of material that is both transparent and electrically conductive. This material, made of a thin layer of copper and a layer of silicon dioxide, could be used in a variety of applications, including touch screens and solar cells.
3. Researchers at the University of California, Berkeley have developed a new type of microscope that uses infrared light to image structures within biological tissues. This technology could potentially allow for non-invasive imaging of living tissue at high resolution.
4. Scientists at the University of Glasgow have developed a new type of laser that is more efficient and powerful than traditional lasers. This technology could potentially be used in a wide range of applications, including medical treatments and industrial manufacturing.
5. Researchers at the University of Sussex have developed a new type of hologram that can display multiple images when viewed from different angles. This technology could potentially be used in a variety of applications, such as security and entertainment.
/home/admin/Developments/HIK Inspire V2.0/Common/include/tconfig.h:166: error: explicit specialization in non-namespace scope ‘class TConfig’ template<> ^
这个错误是因为在类的非命名空间作用域中使用了显式模板具体化(explicit specialization)。在C++中,显式模板具体化必须在命名空间作用域中完成,因为它们是模板的一部分,而不是成员函数或成员变量。
要解决这个问题,可以将显式模板具体化放在命名空间作用域中,或者使用其他方式完成类模板的特化。例如,可以使用成员特化(member specialization)或偏特化(partial specialization)来完成模板特化。具体来说,成员特化和偏特化的语法如下所示:
```
// 成员特化
template <>
void TConfig::member_function_name<specialized_type>(args...) {
// function implementation
}
// 偏特化
template <typename T>
class TConfig<T*> {
// class implementation
};
```
通过使用成员特化和偏特化,可以在类的非命名空间作用域中完成模板特化,从而避免了这个错误。
