1. A device for in vivo tissue diagnosis, the device comprising:
a cantilever beam;
an indenter comprising a first end connected to the cantilever beam and an indenter tip at a second end opposite from the first end of the indenter;
a light source configured to provide light;
a plurality of optical fibers disposed on the cantilever beam, the light provided by the light source traveling through the plurality of optical fibers;
a light sensor configured to sense the light provided by the light source;
a main housing in which the cantilever beam is disposed;
a lens disposed adjacent to the light sensor;
an illumination tube disposed adjacent to the lens; and
an electronic unit that comprises the light source, a spectrometer, and a microprocessor,
the electronic unit being disposed at a first end of the main housing,
the light sensor being disposed at a second end of the main housing opposite from the first end of the main housing,
the main housing comprising a hole through which the indenter protrudes,
the indenter tip being a spherical indenter tip,
the plurality of optical fibers comprising an excitation optical fiber and an emission optical fiber disposed in the indenter,
the indenter tip comprising a first hole through which light from the excitation optical fiber exits and a second hole through which light is collected by the emission optical fiber,
the light sensor comprising a dichroic mirror,
the light source being a laser light source,
the cantilever beam extending in a first direction,
the indenter extending away from the cantilever beam in a second direction perpendicular to the first direction,
the cantilever beam comprising an elastic material,
the electronic unit being configured to perform spectroscopic measurements of tissue during use,
the plurality of optical fibers further comprising an optical fiber configured for spectroscopy measurements, and
the device being a handheld device.
