In recent decades thanks to advances in computing, it has been possible to apply Deep Learning technologies to fields in which they were not previously viable.

Obtaining a depth map is not a easy task, as for the past 30 years a wide array of methods has been developed, with varied results. In this blog, those methods will be discussed.

The study of the ocular aberrations is an important field concerned in ophthalmology due to the great amount of visual quality information that we can obtain from it.

Wave Front Phase Imaging (WFPI), a new wafer geometry technique, is presented, that acquires 7.65 million data points in 5 seconds on a full 300mm wafer providing lateral resolution of 96µm.

In this work, we characterize the in vivo ocular optics of the human eye with a lateral resolution of 8.6 microns, which implies roughly 1 million measurement points for a pupil diameter of 9 mm.

In this work, we characterize the in vivo ocular optics of the human eye with a lateral resolution of 8.6 microns, which implies roughly 1 million measurement points for a pupil diameter of 9 mm. The results suggest that the normal human eye presents a series of hitherto unknown optical patterns. This discovery could have a great impact on the way we understand some fundamental mechanisms of human vision.

The Radon transform is a valuable tool in inverse problems such as the ones present in electromagnetic imaging.

The problem of reconstructing a depth map from a sequence of differently focused images (focal stack) is called Depth from focus. The core idea of this method is to analyze the sharpness of each pixel and compare it along the axis of the focal stack to estimate the true depth value. This approach has two main drawbacks: it depends on the optics of the camera and on the focus measure operator…

The Radon transform is a valuable tool in inverse problems such as the ones present in electromagnetic imaging. Up to now the inversion of the multiscale discrete Radon transform has been only possible by iterative numerical methods while the continuous Radon transform is usually tackled…

WFPI is based on registering the intensity distribution at two different optical planes using two conventional imaging sensors while acquiring two images with the exact same field of view.
