Figure.26.4.presents.a.microscope.image.of.the.edge.of.the.multi-core.iber.that.is.being.
illuminated.at.a.wavelength.of.632.nm..The.probe.presented.in.Figure.26.4.has.about.5000.
cores,.but.the.actual.spatial.resolution.even.with.this.number.of.cores.might.be.larger.due.
to.super.resolution.processing,.which.is.to.be.elaborated.in.the.next.section..Thousands.
of.individual.light.channels.transmitting.spatial.information.at.wavelength.of.632.nm.are.
shown.in.Figure.26.4..Each.channel.is.basically.a.different.pixel.in.the.constructed.image.
As. previously. mentioned,. the. fact. that. each. pixel. is. transmitted. individually. and.
that. the. endoscope. is. basically. a. multi-core. iber. rather. than. a. multi-mode. iber. allows.
the. generation. of. an. image. that. is. insensitive. to. the. bending. of. the. iber.. This. is. a. very.
important.property.since.in.endoscopy,.the.device.will.go.into.the.body.and.it.might.often.
be.bent.during.the.medical.procedure.
