Optical MIDO – Multiple Inputs - Digital Output – device

Coherent Optical Multiple-Input Multiple-Output communication

We propose and demonstrate the Coherent Optical Multiple-InputMultiple-Output (COMIMO) communication technique. In analogy to the spatial diversity in wireless communication, the concept exploits the modal diversity, inherent in a multi-mode fiber (MMF), to transmit independent data channels through a single fiber without the need for wavelength division multiplexing. Central to the MIMO concep...

Multiple-input-multiple-output Multispot-diffusing in Optical Wireless Communication

In Optical (infrared) wireless communications. The main concern is power efficiency. Multi spot diffusing multiple input multiple output (MSD-MIMO) system configuration offer an attractive solution for indoor application. In this configuration transmitter generated multiple narrow beam of light that get uniformly spread over a reflection surface accessible to a service area and can be turn on a...

Multiple Input Multiple Output Indoor Optical Wireless Communication System

Indoor optical wireless communication systems offer a huge potential to provide high speed data transmission for various indoor applications like in flight entertainment, video transmission and other multimedia services. These systems use LEDs as the source which can transmit and receive data by flashing light at a speed which is undetectable to the human eyes. In this paper we review the deplo...

Multiple - Input Multiple - Output ( MIMO ) Optical Wireless Communications

Optical Scatter Imaging with a digital micromirror device.

We had developed Optical Scatter Imaging (OSI) as a method which combines light scattering spectroscopy with microscopic imaging to probe local particle size in situ. Using a variable diameter iris as a Fourier spatial filter, the technique consisted of collecting images that encoded the intensity ratio of wide-to-narrow angle scatter at each pixel in the full field of view. In this paper, we r...
