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.

A camera capable of quickly updating a region of interest (ROI) in its sensor array is provided. The camera is configured to image individual scan lines of a scan imager created as a scan beam is scanned across a subject. A different ROI is defined for each scan line to be imaged. To achieve this, a table of ROI-defining entries is loaded into the camera prior to imaging the scan lines. The ROI-defining entries are used to update the sensor's ROI during the camera's Frame-Overhead-Time. In this manner, the ROI is changed in between the imaging of consecutive scans lines.

Disclosed herein is a high throughput optical scanning device and methods of use. The optical scanning device and methods of use provided herein can allow high throughput scanning of a continuously moving object with a high resolution despite fluctuations in stage velocity. This can aid in high throughput scanning of a substrate, such as a biological chip comprising fluorophores. Also provided herein are improved optical relay systems and scanning optics.

An optical scanner includes a light source to emit irradiation light, a light deflector to scan the irradiation light emitted from the light source in a first scanning direction and in a second scanning direction intersecting with the first scanning direction, a photodetector to detect the irradiation light when the light deflector scans a detection field, and circuitry to turn on the light source in a first irradiation field scanned by the light deflector from the detection field to an end in the first scanning direction and turn on the light source in a second irradiation field scanned by the light deflector from the end in the first scanning direction towards the detection field, and cause an edge of the first irradiation field on the detection field side to move to get close to the detection field from a position away from the detection field.

Examples are disclosed that relate to scanning display systems. One example provides a display device comprising a controller, a light source, and a scanning mirror system. The scanning mirror system comprises a scanning mirror configured to scan light from the light source in at least one direction at a resonant frequency of the scanning mirror, and an electromechanical actuator system coupled with the scanning mirror and being controllable by the controller to adjust the resonant frequency of the scanning mirror.

Digital camera comprising an upright Wide camera configured to provide a Wide image with a Wide image resolution and a folded Tele camera configured to provide a Tele image with a Tele image resolution higher than the Wide image resolution, the Wide and Tele cameras having respective Wide and Tele fields of view FOV.sub.W and FOV.sub.T and respective Wide and Tele image sensors, the digital camera further comprising a rotating OPFE operative to provide a folded optical path between an object or scene and the Tele image sensor, wherein rotation of the OPFE moves FOV.sub.T relative to FOV.sub.W. In some embodiments, a rectangular FOV.sub.T is orthogonal to a rectangular FOV.sub.W. When included in a host device having a user interface that displays FOV.sub.T within FOV.sub.W, the user interface may be used to position FOV.sub.T relative to FOV.sub.W, scan FOV.sub.T across FOV.sub.W and acquire, store and display separate Wide and Tele images, composite Wide plus Tele images and stitched Tele images. The positioning of FOV.sub.T within FOV.sub.W, can be done automatically (autonomously) by continuously tracking an object of interest.
