Integration of a portable MEMS-based double clad PCF (Photonic crystal fibers) endoscopic imaging probe for nonlinear optical microscopy
Nonlinear optical microscopy by using nonlinear optical effects such as two-photon absorption and second harmonic generation (SHG) exhibits advantages of an inherent sectioning ability, relatively deep optical penetration, and direct visualization of intrinsic indicators within biological tissue. However, in order to perform in vivo nonlinear optical imaging in the internal organs, the development of an endoscope probe is essential to deliver, steer and collect optical beam.
In order to further obtain in vivo 2D images, a portable endoscope probe with a 2D MEMS scanning mirror integrated is built based on the same nonlinear optical system. The mirror is integrated with the fiber, an Al coated prism and the GRIN lens to form a forward imaging probe capable of bi-directional scanning. With the MEMS mirror being used as the scanning unit and the GRIN lens to produce a fast scanning focal spot, the compact and portable endoscope has great potential for in vivo applications.
