Abstract

We present a high resolution and high frame rate (HRHF) Lissajous scanning. The Lissajous scanning was achieved by the selection rule of scanning frequencies, i.e., optimizing the greatest common divisor of transverse driving frequencies and the sum of transverse driving frequency ratios. HRHF Lissajous fiber scanner provides 10 fps with 89.5 % fill factor at driving frequencies of 1000 Hz and 1210 Hz, unlike conventional Lissajous scanners. This new method offers the highest fill factor during the shortest period to provide a new direction for real-time high resolution laser scanning. HRHF MEMS Lissajous scanners can be applied for an endomicroscopy and a pico projector.
