Custom CMOS Image Sensor with Multi-Channel High-Speed Readout Dedicated to WDM-SDM Indoor Optical Wireless LAN

چکیده
Visually-assisted optical indoor wireless local area network (LAN) is promising not only for high-speed but for offering intuitive user interface. Free-space optical communications (FSOC)(Jahns, 1994) are a key technology to create image-based ultra-fast wireless communication systems of the future. Compared with radio-frequency (RF) electromagnetic waves, the outstanding features of free-space light in terms of wireless communications are two-dimensional imaging with lenses as well as much higher frequency (> 100 THz), spatial and wavelength parallelism, and security. I believe that fusion of imaging and free-space optical communications can dramatically improve usability of indoor wireless LANs (Barry, 1994; O'Brien, 2005; Nonaka, 2006).

Indoor Non-directed Optical Wireless Communications - Optimization of the Lambertian Order
For an indoor non-directed line of sight optical wireless communication (NLOS-OWC) system we investigate the optimized Lambertian order (OLO) of light-emitting diodes (LEDs). We firstly derive an expression for the OLO from a conventional Lambertian LED model. Then, we analyze the indoor multi-cell NLOS-OWC channel characteristics including the optical power distribution and the multipath time ...

متن کاملA High-Sensitivity Oversampling Digital Signal Detection Technique for CMOS Image Sensors Using Non-destructive Intermediate High-Speed Readout Mode
This paper discusses the possibility of a high-sensitivity digital signal detection technique using frame oversampling and a CMOS image sensor with non-destructive high-speed intermediate high-speed readout mode. Simulation results show that the frame oversampling is very effective to reduce output amplifier noise and quantization noise of ADC.
