SkyWave is a desktop application by InnovationForesight that uses AI-based wavefront sensing (AIWFS) to analyze telescope optics. You feed it a defocused star image ...

Appotronics has introduced a new Laser+LCoS optical engine for augmented reality, utilizing a laser light source to achieve extreme miniaturization for all-day wearable AR devices. Appotronics’ ...

Treatment concept During static arc delivery, the patient is placed in an upright position and rotated to the planned treatment angles; the beam is switched off during rotation and only delivered in ...

For the application of continuously adjustable optical fiber delay lines, a large delay range can increase the instrument’s measurement range. Increased insertion loss of components will reduce the ...

The collimator is an essential part of the fiber optic rotary joint design. This study proposes the Large-Beam Fiber Collimator (LBFC) with a double collimating lens and a Thermally Expanded Core (TEC ...

Reliable and accurate calibration for a four-quadrant detector (QD) is a prerequisite for high-accuracy laser auto-collimation measurements. However, the calibration accuracy is limited largely by the ...

Optical see-through (OST) augmented reality head-mounted displays are quickly emerging as a key asset in several application fields but their ability to profitably assist high precision activities in ...

Abstract: The alignment method based on moiré imaging has been wildly used for its high accuracy of physical measurement, which utilized the phase of moiré fringe to measure the relative linear ...

Noncontact, depth-resolved, optical probing of retinal response to visual stimulation with a <10-μm spatial resolution, achieved by using functional ultrahigh-resolution optical coherence tomography ...
