The model should then be used to estimate the PSF at the target ... calculation of the impulse response of an optical system with a positive lens. Under Fresnel diffraction, we simplify Eq. 15 to ...

Recent research has focused on various types of DOEs, including Fresnel lenses, diffraction gratings, and specialized designs like the lobster eye telescope, which are tailored for specific ...

The company finally unveiled the new system in September, outing it as OpenAI’s first “reasoning” model and renaming it “o1.” Much like the two-stage release of GPT-2, where a stripped ...

The 5.2 μm pixel pitch allows the detection of Fresnel diffraction fringes, which enables the observation of borders and interfaces in samples. A simple experimental set-up comprised of a microfocus, ...

Eco-Friendly vehicles have a minimum EPA-estimated mileage of 35 mpg combined and include hybrids, diesels and even a few fuel-sipping gas-only cars. May require specific trim level and/or ...

Prominent light bar gives Model Y a different look from its Model 3 sibling ...

The capability of multiple orbital angular momentum (OAM) modes generation with high resolution and diversified functionalities in the visible and near-infrared regime is challenging for flat and ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

Pull requests help you collaborate on code with other people. As pull requests are created, they’ll appear here in a searchable and filterable list. To get started, you should create a pull request.

Abstract: The theory of the diffraction grating pair is developed by expanding the frequency dependence of the phase shift as far as the quadratic frequency term. The analogy between pulse compression ...
