Hello Friends, Last time I have discussed holography and written that it is a two-stage process. The first stage is the recording of the hologram
Last time I have discussed the basic definition of holography and hologram. Today I will discuss the process with the help of which hologram is
The word holography originates from the Greek words “holos” (complete) and “graphos” (writing). Thus, it is the technique to record the complete picture of an
Lasers have applications in almost every field like medicine, industry, communication, and science and technology. These applications are due to the directional, coherent, and monochromatic
In my earlier articles I have discussed the basics of Q-switching and three of its techniques known as mechanical shutters, rotating reflector method and passive
