Differential wavefront curvature sensor

In this paper, a wavefront curvature sensor is presented. This sensor is based on the measurements of the differentials of wavefront slopes, where the wavefront slope measurements can be achieved by a Shack-Hartmann sensor. A ShackHartmann sensor with three output collimated beams will be introduced with a lenslet array installed in each beam. By shifting two of the Shack-Hartmann grids in the ...

Hartmann-Shack sensor ASIC’s for real-time adaptive optics in biomedical physics

Hartmann-Shack wavefront sensors are widely used to measure wavefront aberrations. Their applications in biomedical physics are mainly in the fields, where lasers are used for diagnostics or treatment, especially in opthalmology. In a number of applications, e.g. retina scanning, the imaging performance is limited by temporal aberration fluctuations. A fast Hartmann-Shack sensor in combination ...

Coherent laser phase retrieval in the presence of measurement imperfections and incoherent light.

Phase retrieval is a powerful numerical method that can be used to determine the wavefront of laser beams based only on intensity measurements, without the use of expensive, low-resolution specialized wavefront sensors such as Shack-Hartmann sensors. However, phase retrieval techniques generally suffer from poor convergence and fidelity when the input measurements contain electronic or optical ...

Adaptive optics widefield microscope corrections using a MEMS DM and Shack-Hartmann wavefront sensor

We demonstrated the used of an adaptive optic system in biological imaging to improve the imaging characteristics of a wide field microscope. A crimson red fluorescent bead emitting light at 650 nm was used together with a ShackHartmann wavefront sensor and deformable mirror to compensate for the aberrations introduce by a Drosophila embryo. The measurement and correction at one wavelength impr...

Evaluating the effect of transmissive optic thermal lensing on laser beam quality with a shack-hartmann wave-front sensor.

We examine wave-front distortion caused by high-power lasers on transmissive optics using a Shack-Hartmann wave-front sensor. The coupling coefficient for a thermally aberrated Gaussian beam to the TEM(00) mode of a cavity was determined as a function of magnitude of the thermally induced aberration. One wave of thermally induced phase aberration between the Gaussian intensity peak and the 1/e(...
