Prior to this, the desire to generate such a so-called "small concave imaging" required a large number of cameras and sensors, which must be installed around the vehicle in the automotive industry. Thanks to this new approach, researchers have been able to use sensors to produce cameras that reflect super-wide areas like the eagle eye. In addition to the automotive industry, researchers are also looking into the future of smartphones or medical applications.
What is the experience of having an "Eagle Eye"? Probably it is a quick distinction between surgeons and spies who look similar. Thanks to a new camera, the eye works the same way as the eagle eye, although it is not as good as a grain of salt. Using spy tools as a reference, scientists began researching microlenses a few years ago, and the new version improved the field of view and focus of the lens.
According to the report of Approaching Science, the latest version created by researchers uses 3D printers for injection molding, and its performance is no different from Hawkeye. The camera uses four lenses, each of which is set to a different focal length and mounted on an image-reading microchip that compiles the data from four lenses into a single image. These microlenses work by mimicking the principle known as foveal foveal vision, allowing many capturers to see a wide field of view at low resolution while focusing on a single object with high resolution.
The reason why humans can acquire such power is because of our fovea, a small concave on the back of our eyes, filled with cone-shaped cells that can perceive color, which is the only place where light directly illuminates the cone. The eagle has a lot of cones, so its central recess is deep, which is why people use the "eagle eye" to describe the omnidirectional vision.
However, this chip still has some limitations: its resolution is too low, for some special types of surgery, the chip is still too bulky. It takes a certain amount of time for each individual lens to be printed in 3D. However, once these restrictions are resolved, these miniature lenses will likely enter our blood vessels or be used as ultra-small unmanned reconnaissance aircraft to monitor criminals.
The so-called portable projector, also known as pocket projector, mainly through the 3M LCOS RGB three-color projector and decoding technology, the traditional huge projector is compact and portable, making the projection technology closer to life and entertainment.
Advantages compared with traditional projectors:
1. Small size, light weight, easy to carry.
2. Low calorific value and low noise.
3. The price is relatively cheap.
4. Most models support wireless connection through software projection.
Applicable fields:
1. Replace some functions of TV: some machines can have built-in CMMB function, or can be directly connected to the set-top box to put TV, which can be used as a 21-inch TV during the day and a 60-100-inch TV at night (Note: Because of lumen and resolution issues, lumens during the day If the degree is not enough, it must be projected at a close distance) to achieve the effect of home theater; it is convenient to move and break through the traditional film and television space. Even if you are on the mountain, you can also share today's TV series, movies, and MTV with your lover.
2. Business trip: Portable projectors are easy to carry because of their small size and light weight. When you need to display computer content or mobile phone content, you only need to connect the portable projector to achieve the demonstration effect.
3. Private space: For dormitory beds or small private spaces, in the absence of a computer, you can use a portable projector to project the content of your mobile phone to watch video pictures, etc., without staring at the mobile phone at close range.
