A focus scan type imaging device for imaging a target object in a sample that induces aberration proposed. The device includes: a light source unit for emitting a beam; an optical interferometer for splitting the beam emitted from the light source into a sample wave and a reference wave, and providing an interference wave formed by interference between a reflection wave that is the sample wave reflected from the sample and the reference wave; a camera module for imaging the interference wave; a scanning mirror disposed on an optical path of the sample wave of the optical interferometer and configured to reflect the sample wave to cause the sample wave to scan the sample; a wavefront shaping modulator disposed on the optical path of the sample wave of the optical interferometer; and an imaging controller configured to operate in a phase map calculation mode and in an imaging mode.

Examples are disclosed herein related to controlling a scanning mirror system. One example provides a display device, comprising a light source, a scanning mirror system configured to scan light from the light source in a first direction at a first, higher scan rate, and in a second direction at a second, lower scan rate, and a drive circuit configured to control the scanning mirror system to display video image data by providing a control signal to the scanning mirror system to control scanning in the second direction, and for each video image data frame of at least a subset of video image data frames, combining the control signal with an adjustment signal to adjust the scanning in the second direction, the adjustment signal comprising a low pass filtered signal with a cutoff frequency based on a lowest resonant frequency of the scanning mirror system in the second direction.

Devices disclosed herein feature a Wide camera with a Wide field of view (FOV.sub.w), a folded Tele camera with a Tele field of view (FOV.sub.T) smaller than the FOV.sub.w and including an optical path folding element (OPFE). The device may be configured to rotate the OPFE to thereby shift FOV.sub.T relative to FOV.sub.w in response to recognition of an object or subject of interest detected in FOV.sub.w or FOV.sub.T. The device can have high resolution in this overlapping FOV either by fusing the Wide and Tele images or by capturing and saving the Tele image.

Optical systems including lens assemblies and methods of imaging fields of view using such optical systems are disclosed. An optical system for imaging a two dimensional field includes a first lens assembly, a first scanning mirror, a second lens assembly, and a two dimensional image sensor. The first lens assembly has a first transform function whose output is within 0.1% of f.sub.1*(c.sub.1*θ.sub.1+(1−c.sub.1)*sin(θ.sub.1)) for any ray of light that traverses the first lens assembly from a center of an entrance pupil of the first lens assembly at an angle θ.sub.1 relative to an optical axis of the first lens assembly. f.sub.1 is a focal length of the first lens assembly, and −0.5<c.sub.1<2.
