Laser Based Transmitter And Receiver

We have started accepting articles by online means directly through website. EFY was launched inand is counted amongst the leading publications in the fields of electronics and technology—across the globe. Transmtiter do laser torch based voice transmitter and receiver full report have the circuit diagram of laser transmittter transmitter and wireless laser communication receiver. This electronic media starting from satellite communications had invented new dimensions in the field of wireless communication, research in these areas created a new concept of communication by means of lasers, no one ever expected this kind of development in communication strategies and its always a raising question that how we communicate by implementing lasers, in our project we give a detailed answer about how transmiyter communicate with others by using laser technology.
