Sophisticated wavefront sensors are critical in high-precision optical metrology across a range of fields, including ophthalmology, astronomy, and semiconductor inspection. These systems depend on ...

A new depth sensor claims to address the limitations of standard indirect Time-of-Flight (iToF) sensors by enabling depth sensing up to 30 meters, or four times more than standard iToF sensors, all ...

Abstract: In this paper we discuss the ability of Shack-Hartmann wavefront sensor to be used in the closed loop adaptive system. For sure we do not discuss the possibility of wavefront sensor to ...

I have been using this package for quite a while to simulate various spot patterns for the Shack-Hartmann wavefront sensor. While doing that, I also generated the focal_grid and propagated the ...

I have a few queries regarding this part of the code. The array x is defined as (pupil_diameter, pupil_diameter) with a step size of lenslet_diameter. But shouldn't it be (-radius, radius) as the ...

In wavefront characterization, often the combination of a Shack-Hartmann sensor and a reconstruction method utilizing the Cartesian derivatives of Zernike circle polynomials (the least-squares method, ...

Abstract: Wavefront sensing is important in many optical measurement systems and adaptive optics. The speed of the wavefront sensor determines the achievable temporal resolution of dynamic ...
