Summary
Pixelated lenses can achieve an apodized point-spread function due to their finite pixel size. This study numerically evaluates how pixel parameters influence apodization and point-spread function enlargement for optical applications.
Area of Science:
- Optics and Photonics
- Micro-optics
- Image Formation
Background:
- Traditional lenses suffer from diffraction-limited performance.
- Apodization techniques aim to suppress far-field side lobes.
- Pixelated optics offer novel ways to control light propagation.
Purpose of the Study:
- To demonstrate that pixelated lenses can exhibit an apodized point-spread function.
- To numerically evaluate the degree of apodization and associated enlargement.
- To analyze the influence of pixel lens parameters on optical performance.
Main Methods:
- Numerical evaluation of the point-spread function.
- Analysis of optical performance based on pixelated lens parameters.
- Characterization of apodization and spot enlargement.
Main Results:
- A pixelated lens with specific parameters demonstrates an apodized point-spread function.
- The finite pixel size is identified as the origin of apodization.
- The degree of apodization and spot enlargement are quantified in relation to lens parameters.
Conclusions:
- Pixelated lenses are a viable approach for achieving apodization.
- Control over pixel parameters allows for tuning of the point-spread function.
- This research provides insights into the design of advanced optical elements.

01:16Focusing of Light in the Eye
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
01:18Imaging Biological Samples with Optical Microscopy
Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.

01:18Aliasing
Accurate signal sampling and reconstruction are crucial in various signal-processing applications. A time-domain signal's spectrum can be revealed using its Fourier transform. When this signal is sampled at a specific frequency, it results in multiple scaled replicas of the original spectrum in the frequency domain. The spacing of these replicas is determined by the sampling frequency.
If the sampling frequency is below the Nyquist rate, these replicas overlap, preventing the original signal...

01:20Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
