Super-resolution Fluorescence Microscopy

Super-resolution Fluorescence Microscopy

Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...

Light Acquisition

Light Acquisition

In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Area of Science:

Optoelectronics
Wireless Communication
Image Sensing Technology

Background:

Complementary Metal-Oxide-Semiconductor (CMOS) image sensors are ubiquitous in mobile devices and cameras.
Utilizing these sensors as visible light communication (VLC) receivers offers a promising avenue for integrated communication systems.
Significant challenges exist in adapting CMOS image sensors for reliable VLC reception.

Purpose of the Study:

To propose and demonstrate a functional VLC link employing a standard mobile-phone camera as the receiver.
To achieve data transmission rates surpassing the inherent frame rate limitations of CMOS image sensors.
To analyze and mitigate the unique challenges associated with using CMOS image sensors in a VLC context.

Main Methods:

Analysis of CMOS image sensor characteristics: rolling shutter, pixel exposure overlap, frame-to-frame processing gaps, and blooming.
Development of synchronization and demodulation techniques tailored for image sensor-based VLC.
Implementation of file format conversion, grayscale conversion, strategic column matrix selection to avoid blooming, and polynomial fitting for threshold determination.

Main Results:

Successful demonstration of a VLC link utilizing a mobile-phone camera.
Achieved data rates higher than the CMOS image sensor's frame rate.
Bit-error-rate (BER) evaluations met the forward error correction (FEC) threshold, indicating reliable data transmission.

Conclusions:

CMOS image sensors can be effectively repurposed as VLC receivers, even at high data rates.
The developed synchronization and demodulation methods successfully address sensor-specific limitations.
This research paves the way for novel, low-cost VLC applications leveraging existing mobile hardware.
