Abstract: An imaging system configured to transform a lateral scan motion into axial refocusing, thus enabling aberration free remote focusing. In one embodiment, the imaging system provides aberration free remote focusing by causing a beam of light to be scanned over a stationary mirror having a variable height in the scan direction, thereby causing the beam of light to be defocused in an axial direction in the return direction (e.g., the direction of propagation for the reflected beam of light). By configuring the back-reflected light resulting from the lateral scan component as described herein, a pure axial scan motion may be obtained at the rate of the employed (lateral) scanning technology (e.g., a GSM). This capability allows the imaging system of the present inventive concept to leverage rapid lateral scan technologies to produce rapid axial displacement of the axial focus of the beam of light.
