A 2023 investigation introduced a subaperture superposition technique for Shack–Hartmann sensors that robustly improves the signal-to-noise ratio when observing faint objects, facilitating more ...

The seismic signature of a fireball meteoroid event can be used to tell whether the fireball fragmented or remained intact as ...

While roboticists have introduced increasingly advanced systems over the past decades, most existing robots are not yet able ...

The Auto Lensmeter LM-1800PD / 1800P features Hartmann Sensor with 108 multiple measurement points. It is user-friendly and has tiltable LCD with 5.7-inch touch color panel. The LCD monitor ...

A meta-lens array-based Shack-Hartmann wavefront sensor enhances phase measurement by increasing sampling density and angular resolution, advancing optical wavefront sensing with metasurface ...

ST. LOUIS – June 30 marks Arch 630 Day, celebrating the Gateway Arch’s unique dimensions and history in St. Louis. Arch 630 Day honors the historic monument and its dimensions, which stand at ...

We provide a multi-sensor dataset containing red-green-blue (RGB)-D and motion tracking data from sequential human-to-human object handovers. We recorded 12 pairs of participants executing shelving ...

The proposed sensor exhibits the features of low power consumption, noncontact force sensing, and miniaturization. Therefore, this sensor could be applied to movable objects, e.g., tension sensing for ...
