Abstract: A method and a stereoscopic apparatus configured to determine an exposure time period for capturing images. The apparatus comprises at least one image capturing device for capturing pairs of images; a processor configured to: calculate a texture-signal-to-noise ratio (TSNR) metric based on information derived from a pair of captured images; calculate an image saturation metric based on that pair of captured images; calculate a value for an exposure duration that will be implemented by the at least one image capturing device when another pair of images are captured; provide the value of the calculated exposure time period to each at least one image capturing device; and wherein the at least one image capturing device is configured to capture at least one image of the target while implementing each the respective calculated value of the exposure time period provided to the corresponding one of the at least one image capturing device.

Abstract: A projector includes a first laser source projecting a first laser beam, a second laser source projecting a second laser beam at an angle with respect to the first laser beam, and a mirror reflecting the first and second laser beams. Circuitry controls the mirror to simultaneously reflect the first and second laser beams in a first scan pattern to form a first image having a number of scan lines greater than two times a horizontal resonance frequency of the mirror divided by a desired frame rate of the first image. The first laser beam forms a first angle of incidence with the mirror and the second laser beam forms a second angle of incidence with the mirror, the second angle of incidence being equal to the first angle of incidence summed with the angle of the second laser beam with respect to the first laser beam.

Abstract: A probe, including an ablation element which is configured to perform ablation of tissue. The probe also includes an ultrasonic transducer, located in proximity to the ablation element, which is configured to transmit acoustic radiation force impulses (ARFIs) to the tissue, and to measure a displacement of the tissue in response to the ARFIs so as to monitor the ablation of the tissue.

Abstract: Disclosed herein is a circuit for determining failure of a movable MEMS mirror. The circuit includes a mirror position sensor associated with the movable MEMS mirror and that generates an analog output as a function of angular position of the movable MEMS mirror. An analog to digital converter converts the analog output from the mirror position sensor to a digital mirror sense signal. Failure detection circuitry calculates a difference between the digital mirror sense signal at a first instant in time and the digital mirror sense signal at a second instant in time, determines whether the difference exceeds a threshold, and indicates failure of the movable MEMS mirror as a function of the difference failing to exceed the threshold.
