who um so my my lab specialise is in uh making um hard i'm serving hard imaging
00:00:08
problems uh for example we've we've design the smallest uh endoscope the size of the hair
00:00:14
to look at that sells uh in the body or we
00:00:16
designed um uh displays for men to the virtual reality
00:00:21
so rather than giving you a hodgepodge of what we've done i wanted to
00:00:25
illustrate a little bit what's uh what we do with one example
00:00:29
example of shows is a um use a a tool for optimal g.
00:00:34
uh so uh last year of them are just came to to see us to see if we can sort of a heart problem
00:00:41
so the problem is this if you have uh the retina that you can see a here
00:00:47
and the recognise composed of of um many cells hundreds of cells
00:00:52
and the importance sells uh for example the gangly in
00:00:55
this uh there are a line the top of the retina
00:00:58
another for the receptors that convert a photons to electrical
00:01:02
and so if you wanna um uh uh see what's happening so inside the idea is technology and actually in the last twenty years
00:01:08
a lot of technology is being developed to look into the i if you have problems
00:01:13
so for example this is healthy retina when you see the four yeah and you can
00:01:17
see a cat in in in that that's dimension you could see different layers
00:01:22
so if you have a a an accident for example or a mac to the generation we have this
00:01:27
type of of of uh problems in the in the uh and uh in the fall here
00:01:33
there you can see with this technological or c. t. uh it's so every
00:01:36
half of them are just as this uh this type of instruments
00:01:40
however i'm currently of time or just tell us uh that by half
00:01:46
the cells in the in the writing a cat can just not be seen
00:01:51
and the reason is that the the cells are transparent because the light goes through the the cells
00:01:56
it'll reflect light so it's very difficult to uh image than individual
00:02:01
um so they came to us with this hard challenges is it possible to develop technology to actually see
00:02:06
uh uh uh these these cells that are transparent and can be seen have never been seen
00:02:11
in view so this is not the sort of of challenges we will look at
00:02:14
uh and see we can solve with the technology developed in the past
00:02:18
so we actually this is um what he looks like um when
00:02:23
you actually caught and i and and lay down and die
00:02:26
the the cells that's what again instead looks like she's never been observed in in the in the real thing people ah
00:02:34
so we developed this is a technology that uh is different in the sense that in this example here
00:02:39
will when it's not through the through the uh to the i thirty pupil rather through the skin
00:02:45
of of the i. so it's unconventional was typically every instrument look uh look you
00:02:49
have to look straight to the to mention here we look a sideways
00:02:54
so the advantage of this method uh is that it's a reflex lights in the back of the eye
00:02:59
and is a light uh is not uh the the spectral light is not going back into the instrument
00:03:05
so it's as if you have a source of light that is directly coming from the back of the yeah
00:03:10
so with this uh they days we actually used technology uh uh that would develop for looking at
00:03:16
at uh at cells interest but in a transparent
00:03:20
um environment and we actually now able to
00:03:26
uh to see these cells and why why's it interesting for tomorrow just because if
00:03:30
you can see the cells of or not to be able to see before
00:03:34
you can uh maybe uh that's the the the disposition that you can
00:03:37
if you can measure how many cells you have count them
00:03:40
maybe you can uh uh see uh uh foresee problems like mac or
00:03:44
the generation if you can see cells of supporting visible receptors
00:03:48
so these are dying and we don't know why so if we can measure the cells above then maybe it
00:03:52
is it your back to be done uh or so this is the type of images we get
00:03:58
and uh these are haven't been seen before in because of this sort
00:04:02
of a a hodgepodge of technology with european in in years
00:04:05
we've now able to to measure this sells a directly in applying this technology
00:04:11
uh and work with the butt of the largest soul um uh that's uh typically we develop technology
00:04:17
uh where people come with a with a specific problems uh and then uh we find patterns and
