Super slim camera developed to record lenticular images

Engineers have developed a camera system which can create images by integrating the light into responsive surfaces instead of a single focused glass lens. The new technology on the camera systems will open doors to producing image receivers on two-dimensional surfaces.

 

Researchers of the California Institute of Technology (Caltech) in the United States have succeeded in recording images on superfine surfaces without the need for a lens, by the help of the technology they call “optical phase array“.

Researchers who produce a thin sensitive surface from silicon photonic material to fulfill the function of the lens have designed a two-dimensional camera working with 64 different light receivers on an 8 to 8 grid system.

Unlike the glass lens, which collects the light in one spot and creates a visual image, each receiving surface in a specific region, without light, reproduces in a similar way as used in radar technology, in a phased array, strengthening the signal in a certain direction and delaying the others.

Project chief researcher, Ali Hacimiri, a Professor at Caltech, noted that the two-dimensional integrated surface fulfilled the function of the three-dimensional lens, while emphasizing that digital cameras will significantly reduce the volume and cost.

The new logarithm in this new slim-camera will allow for a slight change in the manner of organizing the light, allowing for the widest view, from the shortest point of view, to the longest point of view for the shortest viewpoint.

Using a cheap silicon photonics surface only in paper thinness, it is possible to control all the optical properties of an electronic camera without any mechanical movement, lenses, mirrors, or anything else, to create a whole new world of gateways to which image receivers in the form of wallpaper.

Details of this invention were announced at the American Optical Association (OSA) Laser and Electro-Optics Conference and this study was published in “Technical Digest” magazine.
