The world's first three-dimensional laser intensity correlated imaging engineering prototype by the Shanghai Institue of Optics and Fine Mechanics，China。

Earlier this year, the CAS Shanghai Institute of Optics and Fine Mechanics, Quantum Optics group of love '80' scientists have developed the world's first three-dimensional laser intensity correlated imaging cameras (also called single-pixel abroad dimensional camera), and recently produced the first prototype. although this camera is only a single pixel, but it can easily obtain the subject's holographic image, both in the civil and military fields will flourish(Best News - Breaking News Updates | Latest News Headlines | Photos News).

'80' scientists create 3D camera

According to the Chinese Academy of Sciences Shanghai Institute of Optics and Fine Mechanics, introduced by the scientists that the world's first built the first three-dimensional laser intensity correlated imaging engineering prototype (international peer-also known as 'three-dimensional single-pixel camera'). Learned that the Results from this researcher Han Shensheng led chaired the national '863' project, 'three-dimensional laser imaging technology research association strength' and 'passive optical multi-spectral imaging technology research association strength.' project recently in Shanghai experts organized through the Ministry of Science and acceptance.

Han Shensheng said, the project completed the first international real outdoor scene typical remote sensing intensity associated with three-dimensional laser imaging experiments, and the initial establishment and verification of the microwave imaging associated gaze basic theoretical system.

Concerned about the world's latest technology website 'MIT Technology Review' in early on January 29 this year, first reported Chinese '80' scientists successfully developed in the laboratory of the news cameras, allegedly photographed with this camera can easily obtain the spacecraft holographic images(Military News Best News - Breaking News Updates | Latest News Headlines | Photos News). a signature Gordon Russell's friends quipped: 'With this technology, and soon we will be able to shoot the whole body like a starship!'

Usually we have seen cameras have a unified name - optical imaging, while single-pixel 3D camera did, is the use of light and electromagnetic properties of random fluctuation imaging - namely quantum imaging, commonly known as 'ghost' image.

Conventional optical imaging are reflected in a root object light entering the lens, falling film or electronic components on one spot arranged together to form an image, but the 'ghost' image of nature imagined as a confused by countless photons composed of quantum field and this field will be kept in the photon fluctuations, each state can be calculated. Therefore, to get the image, no longer need to rely on light entering the imaging lens, but only need to rely on energy reflected light detection and Calculation - like ghostly insight into everything we can rely on ideas.

Rendering stealth fighters ineffective

'In Google Maps on the photos, we often see the clouds covered the ground scenery.' Project team members Gongwen Lin introduction, 'but with the 'ghost' imaging methods, will be able to penetrate the clouds a large extent, the ground look. '

Remote sensing imagery is a single-pixel 3D camera is one of the important purposes. According to reports, the project team for the first time in the world a lot sunny, night, clouds, fog and other weather conditions typical outdoor remote sensing imaging experiment. Experimental realization of a wild one kilometer resolution on the order of detection distance 1cm, super-diffraction-limited resolution two times higher than the intensity correlation imaging demonstrated active illumination intensity correlation imaging in three-dimensional imaging capabilities, imaging, detection sensitivity and clouds, fog and other inclement weather conditions and existing remote sensing imaging technology compared to the characteristics and advantages.

Shanghai ray machine in 2012 mid-term project evaluation report shows that the use of single-pixel diameter of only 18mm 3D camera, you can shoot in harsh environments common to 420mm optical telescopes can not shoot the target due to greatly reduce the size and weight small, otherwise require helicopter carrying the remote sensing equipment, and replaced completely after a single-pixel 3D camera can be loaded into a small UAVs.

In addition, the use of 3D holographic imaging camera, the hospital can use ordinary light easy to see the X-rays of human soft tissue injury, disease, radar reconnaissance, will be able to easily distinguish the intrusion detection area is a small bright spot Bird or an aircraft, whether civilian or military field areas, stealth fighter will basically 'failure.'

China overtake the world of quantum optics research

The world's first single-pixel 3D camera's birth, behind without China '80' researchers 'Dream' effort last summer, Chen Mingliang, Lien Rong, XIAOGAN thin compliance Chen Jin Wang and Deng five boys fought in the city, suburban and plateau, a large lake, obtained under various meteorological environmental conditions firsthand beautiful data, validating the world's first application in natural conditions 'quantum camera.'

In light machine in a corner, stood a large container. Unusually, this container was loaded with air conditioning, but also opened a window on the side. Gongwen Lin told reporters that this is their field test of the 'mobile homes': Instrument device is almost filled up all the space, leaving one space, enough 4 people stood huddled together. etc. Remove the instrument, you can have 'half room' for them to rest when on duty in the field, although there is air conditioning, It is the instrument blowing hot and cold too exhausted machines help people - when they saw a simple residential construction sites are the envy.

In order to transport equipment to the test site, they and the local herders together, with two-meter-long stone bar, paved path through different weather conditions in order to obtain a device imaging data, in the highlands of strong sunlight, sun off their skin layer after layer.

1997, Chinese-American scientist Steven Chu to Quantum Optics have won the Nobel Prize in Physics, when he lamented that 'common start' in Chinese counterparts, as many other experimental constraints and funding in this 'race' in the behind. He said, 'China-friendly' is the Shanghai-ray machines in quantum optics lab.

Now, let's turn this laboratory work American counterparts surprised the project leader, Shanghai Institute of Optics and Fine Mechanics Institute researcher Han Shensheng says that when the gap in the past decade has gradually tied. '80' this generation 'Standing on the threshold of an era, there is hope in the new optical system of a place.'

Single pixel camera makes 3D ghost image

TECHNOLOGY 31 JANUARY 13 by PHILIPPA WARR

A single pixel device which can record three-dimensional images has been built at the Shanghai Institute of Optics and Fine Mechanics in China.

Single pixel "cameras" are already capable of of generating two-dimensional pictures through a process known as ghost imaging, but the team in China has used a timed laser pulse to give the system the ability to detect spatial arrangements.

Ghost imaging works by eliminating the need for traditional imaging equipment such as lenses. The target is illuminated using a modulated light source such as a laser. The scattered light is then detected by the pixel and analysed by a computer program which can piece together an image based on how the target has altered the light source.

For the three-dimensional version Wenlin Gong and his colleagues fired incredibly short laser pulses (ten nanoseconds each) at the target and turned the pixel on at specific times to capture only the light reflected from certain distances. The result is a three-dimensionally layered series of two-dimensional images -- a kind of high-tech decoupage known as laser detection and ranging (LADAR).

Being able to exploit lens-free image creation creates a low-cost alternative to expensive imaging systems. According to Technology Review "it is possible to record the equivalent of a five megapixel [5,000,000 pixel] image using just 50,000 pixels".
