Optical devices are frequently being used in medical applications to image lesions and malignancies, assist with surgical procedures. The advances micro-electro-mechanical systems (MEMSs) optics led the fabrication of flexible endoscopes as small a few millimeters diameter. design sub-millimeter sized optical fiber scanner is presented this paper. proposed consisted vibrating that carried laser...
