Members News: Built A Plenoptic (Lightfield) 4 Dimensional Microscope: Dec 29, 2012.

Recommended Posts

pleecan

I have been experimenting with Lytro LightField Technology for a number of months now....

The Technology was developed at Stanford. I studied the Harvard LightField Microscope design and had a Eureka moment yesterday as I understood the concepts in the Harvard prototype and solved an optics problem and on

On Dec 29, 2012, I constructed a Plenoptic Microscope for myself and it works :

The system is capable of resolving smaller than 10 micron resolution:

Here is a test calibration slide... each division is = 10 microns

An example of the images that it can record is as follows.

I have a new toy to play with.

Ummm... how did you get the fly to stay still for the photo! :P Neat toy you got there Peter. You should start looking for Ostracods in the Arkona matrix now.

This is amazing! Possibly your technological Magnum Opus? :goodjob:

That's a wonderful (and useful) technological application. I will have fun teasing my graduate student daughter. She rushed to get a Lytro camera when they became available. I don't believe she has made the innovative strides you have!

Dave, Chas and Snolly: Thanks for the good wishes... I am so excited with this new technology... this morning I am experimenting with Dark Field microscopy on Plenoptic microscope... it may be a first.... I got an image and will post later on....

Thanks Tim!

This is a first.... Dark Field Microscopy applied to Plenoptic Microscope... think this is real cutting edge stuff :D .

Found this neat work from Stanford:

This research let to formation of Lytro.

Hi Peter,

I'm liking the new change of perspective feature of the Lytro images. That has intersting potential for microscopy. How does the camera perform with thicker, more 3d, slide mounted material?

Hi john: I have also built reflective light non transmission Plenoptic macro set up... works fine.

The world of microscopy is really magic and it seems you have got it into your blood :wub::wub:

You have made me see you coming from the next eon... :o

Thanks Astron! The future is plenoptic imaging... the technology is still in its infancy. I have been suggesting various things to the Lytro people and they are listening with various implementations..... via firm upgrades in the last couple of months including a PC version of the software.

Just got word that Lytro will not support scientific use of their camera nor are they interested in supporting scientific use:

Pitty... I will go it alone without Lytro's help.

Hi Peter,

Gah! Companies like this can be very frustrating at times. Keep up the good work regardless! You are already taking amazing pictures with the camera and I'm sure you will only get better with it.

Thanks John.... I mange to get Bright Field , Dark Field and Reflective Light Plenoptic Microscopy to work..... The power if Lytro is not the consumer market but rather the scientific and industrial sector.... the common Joe on the street does not need advance camera designs .... The Lytro people have implemented a bunch of suggestions so far but the fact that they have no interest to scientific applications is a real shame. Raytrix is catered to scientific and industrial application but costs thousand of dollars ... not affordable to the common consumer.....

Oh by the way I submitted to Nikon micrograph competition with Plenoptic Dark Field shot....... under the make and model of the microscope used... I filled in home made my design :D .
