Hi Alistu,
thank you so much for replying.
Actually i saw this system in a research paper published in Springer. but i was not convinced with the working of this system.there it is shown as an improvement of the system which uses a laser array, in order to reduce its complexity, the author used a single laser.
i wanted to further optimize this system. so should i continue with this system or should i use the array only??
i have attached the paper for your reference. please have a look once and suggest the i should work on this or not.
