Design and development of signal sensing equipment for measuring light transmission efficiency of POF fabrics

Abstract

An attempt has been made to design the light signal sensing equipment with microcontroller AT89C52 based circuit using 02n5777 optical receiver for measuring the light transmission efficiency of poly(methyl methacrylate) based plastic optical fibre (POF) and then to develop POF integrated woven fabrics using three different methods, namely sequential work, handloom and powerloom using 0.25 mm, 0.5 mm and 1.0 mm POF. The signal transferring efficiency of the handloom, powerloom and sequential integrated woven POF fabrics is analysed using the microprocessor designed with optical receiver for bullet wound detection. The signal loss percentage of these fabrics has been studied and reported using the red LED, white light LED (SPL) and laser light LED with input voltage of +5 V. These POF integrated woven fabrics are having good scope for the development of signal transferring garment for defence personnel, telecommunication and data transferring purpose.
