Holography (3 Dimensional imaging)

[@samarjyoti3184]

Seriously the object is this 🗿

[@sprrez]

Lol

[@adritamollik8750]

It was very funny 🤣

[@HeheHom]

I really appreciate how you explained holography from my “instant physics” book; thank you.

[@EngineeringPhysicsbySanjiv]

Sorry but not seen your book.. may be the book that I referred to make this must have referred your book.. I would definitely like to see this book..

[@gabrielkardos4342]

​@@EngineeringPhysicsbySanjivno reply, suspicious? Well executed.

[@gabrielkardos4342]

Just sayin

[@gabrielkardos4342]

​@EngineeringPhysicsbySanjiv thanks for the informative and consise video.

[@AitorKTX]

Hello Sanjiv, Thanks a lot! I have a question. During the recording step, hologram was created (photographic plate) and real object was present. In the reconstruction step, I assume "the real object does not need to be present anymore" is that assumption correct? Thanks a lot!

[@EngineeringPhysicsbySanjiv]

Of course, in the reconstruction real object is not present. 3D image can be viewed any time. but for this we need similar laser beam that was used for constructing the image.

[@AitorKTX]

@@EngineeringPhysicsbySanjiv Great!! Thanks a lot for this clarification

[@melody3741]

Wait a second, your image implies the hologram only shows on the exact point where the laser is shining. Is the laser spread out, or does it stay as a point beam?

[@AroobaKhan-t9p]

Must Must reply... Where the hologramic image is to be formed...???

[@csimalapparikkonam8264]

sir... can you please give a video on spatial frequency filtering?

[@EngineeringPhysicsbySanjiv]

will try.. but it may take time.. because at present i am concentrating on the contents in our syllabus..

[@Strawberry_anxiety]

No

[@momisvlog3465]

Sir I have a question show that for a hologram formed with both the object wave and the reference being plane wave consists of a series of Young's interference fringes having an intensity distribution of cos2 type

[@EngineeringPhysicsbySanjiv]

Its not in scope of our syllabus.. but you can find the answer on the following link in Example 18.1- books.google.co.in/books?id=jStDc2LmU5IC&pg=SA18-PA4&lpg=SA18-PA4&dq=the+hologram+consists+of+a+series+of+Young%27s+interference+fringes+having+an+intensity+distribution+of+the+cos+?+type&source=bl&ots=E0IDKyOYxn&sig=ACfU3U0KUWG2GzqrgRLOmfEdMRHDDYirmA&hl=en&sa=X&ved=2ahUKEwj5ybHmqpryAhVWeH0KHTZHCXQQ6AF6BAgdEAM#v=onepage&q&f=false

[@momisvlog3465]

Thankyou sir

[@EngineeringPhysicsbySanjiv]

@@momisvlog3465 Welcome..

[@heroty8017]

To get Hologram we must use high intensity source?

[@sprrez]

No, it should be a coherent light source which is having same phase.

[@krishnavsaikia9841]

To learn Holography.. I've to do optical engeneering... Isn't it

[@pastuh]

So how Pogs made? They have multiple colors and can be viewed in normal light

[@abhinavprathnakaran6157]

Awesome

[@EngineeringPhysicsbySanjiv]

Thank you

[@sounakbhattacharya9646]

Thank you Sir 🙏 🙏

Sir u forget, who is the father of optical fiber he is indian and u didn't cover him
