measuring the length of the hair follicle under the skin

[mbyka]

This is my new curiosity guys!!!

Is there such a device known?
a device will be able to measure the length of hair follicles under the skin! will graphically display or display the value in mm

How can I view the follicles  under skin? with/on a glcd or tft lcd?

With what kind of technology does such a procedure provide successful results?
subcutaneous imaging technologies

(MR) magnetic resonance
ultrasound
lidar
xray
or another device belonging to technology that I haven't met yet.

Is there anyone who owns the original service manual for these devices? or a site address where I can download?
maybe there is free (open source) viewing software or something!

I want to meet/learn with such technologies ,with the right theoretical and practical knowledge.

You cannot even imagine how much I would like to be able to benefit from the experiences of experienced people who have developed projects on such devices / technologies ...

Why?

[mbyka]

what does it mean this question?

i want to add usefull extra powerfull function for my skin care device...

[solutions]

What are you doing with the information? What "function"?

[bobcat1]

Hi ,

It is possible but complicated , to do this you will need a high resolution ultra sound scanner or a high resolution thermal imager and a budget of million's to develop a product base on this ideas.....

All the best

can high resolution ultra sound scanner detect and show the hair undir skin?
i was know this kind devices are good for human flesh and bone to detect ,show and analyze

  high resolution thermal imager,As the name suggests, these devices are devices that can detect temperature differences.
designing such a device to measure the length of the hair under the skin? thought-provoking !!

I wish such a devices had the original service manuals and I could see its electronic circuit diagrams.

Ultrasound is impossible

[mbyka]

What are you doing with the information? What "function"?

I produce devices used in the field of beauty and cosmetics, skin care devices, laser hair removal devices and so on.
I wanted to make the length of the hairs under the skin visible before and after the session (is it possible?) I'm investigating this.

[solutions]

So, you don't want the length of the hair, you want the depth of the tip of the hair below the skin surface?

[mbyka]

yeahh, yes.

[devetka]

Not sure how will ultrasound work considering cross section of the hair is very small, but in theory you should have some of the soundwaves return, you would have to experiment with different frequencies as standard 35-45kHz might not be high enough.

I'd personally try to attack this with light and photocell. I'd measure how different wavelengths all the way from ultraviolet to infrared are absorbed by the skin where no hair exist vs where there is hair and where there is hair at different length and then try to compare that. It works pretty good for oximeter for e.g. it uses 2 leds at different wavelengths and single photocell, one wavelength is more absorbed when there's oxygen, and the other one more absorbed when there's no oxygen.. ( https://medicine.uiowa.edu/iowaprotocols/pulse-oximetry-basic-principles-and-interpretation ) ... you could try to make experiment with bunch of different light sources to see how will different depth hair affect it

Why?

maybe better than contemplation navel fluff.

devetka;

Frankly, the theoretical ideas that crossed my mind were the same.
for viewing;
1-I will take electrical signals to transfer to a GLCD as shown in the figure.
2-Or using an ir or uv camera (if available) and working on a color tft screen (a kind of image processing) using a sbd board working with a linux os, making a software with qt and pyhton or with c ++.

But it is very important that this device is really successful. It should not be a fake device with fake information.
The most critical part in this project is the detector and how the signals coming from this detector should be processed (by which method).

Where should I start or what software and tools should I use for image processing with qt and phyton or c ++.
Can anyone knowledgeable about this issue help me?

"You should learn to use this program and the following tools.
Or maybe there are ready-made package programs, open source code. "

sorry i could not see what do you mean?

[devetka]

@mbyka, unfortunately I have no experience in image processing so can't help other than "lot of developers use openCV" and that most dermatology instruments I seen use light and camera. You can get some camera with IR filter removed (there are some ready made for rpi), shine different light frequencies and look at the image and try to figure out if you can deduct something from that. As for tools, I'd start with rpi, C/C++ and opencv

[PICker]

I think this paper may help you

[mbyka]

to be honest i found it too
after i read this papers i saw i need the dedector design details and dedector signals processng method what?

thank you

I don't know if this will help, but:

My wife had Non-Hodgkin Lymphoma three times. (!st time systemic, 2nd time ocular, but without breast cancer and the 3rd time she developed a tumor over the motor cortex of her brain.) She survived. The drugs they game her really messed with her endocrine system. So, she grew some facial hair (NOT something to bring up.) So, I took her to a dermatologist here in the US for treatment and here's what I found out:

LASER is no good unless the hair is black. The LASER transmits heat to the hair follicle. it takes many visits and is very expensive over time. The LASER is ineffective against white hair. The white hair scatters the light and the follicle doesn't heat. I work in the medical field and they recommend I grasp the hairs with hemostats (locking forecepts) and pull the hairs out of the skin. It takes time, but is the most effective. When you remove them, it is just like in the books - the hair is attached to a follicle and is about one-forth of an inch under the skin.

I thought about using tape to do it quickly, and my wife offered to castrate me. So I pay attention to her. I hope this helps.

First of all, I wish you a very, very healthy days

There is also a "needle epilation" device for white hair in its production.it is a bit of a laborious task.but it is effective.
Maybe you've heard of it. You can try it if you want (if still needed)

all I care about is the hair under the skin..and being able to measure their height / length (display on a screen)

You can try with ultrasounds

thank you PICke
 also have this document too.
the google !!
but any orginal service manuals(for discover tecnic of elektronic circuit) and also comunucation topology with main board and dedectör ) ..i could not find.

[PICker]

I found the first document in the databases of my University, the second one also as full text on the net.
Unfortunately I was unable to find something different from a technological point of view
I'm sorry it wasn't useful to you, I hope someone can help you and you can solve the problem.

[mbyka]

thank you so much, i will continue try to do somethings...

[PICker]

I checked over 300 abstracts and found only one potentially interesting article even though I don't think it solves your problems yet. I think your project is really innovative.

[mbyka]

Whereas I was thinking that somebody must have done something ... I guess I'll be the first !! if I can.

Have you looked at this paper https://pubmed.ncbi.nlm.nih.gov/21070465/#:~:text=Results%3A%20The%20mean%20length%20of,extends%20down%20to%201.8%20mm.
