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.

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.

A drive apparatus includes an actuator, an engaging body configured to frictionally engage the actuator, and an optical-path-changing member configured so as to be magnetically linked to the engaging body, and configured to change the direction of an optical path. The actuator causes the engaging body to move in a first direction and in a second direction opposite to the first direction. The optical-path-changing member moves due to being biased by the engaging body when the engaging body has moved in the first direction, and the optical-path-changing member moves following movement of the engaging body due to magnetic attraction when the engaging body has moved in the second direction.

A mechanically resonant system exhibits a resonant mode frequency response. A conductor is included on a resonant member within the mechanically resonant system. A current in the conductor causes a modification of the resonant mode frequency response when in the presence of a magnetic field. The modification of the resonant mode frequency response may include an offset in the natural frequency of the mechanically resonant system.

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.
