Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview

Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview

Attenuated total reflectance (ATR) infrared spectroscopy is a powerful analytical technique used to study the composition of materials. It is widely employed in chemistry, materials science, forensic science, and other fields where sample characterization is required. ATR has several advantages over traditional transmission IR spectroscopy, including the requirement of little to no sample preparation and the ability to analyze a wide range of samples.
The ATR process begins by directing a beam...

Focusing of Light in the Eye

Focusing 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...

Area of Science:

Optics and Photonics
Micro-optics Engineering

Background:

Miniaturization in optical systems necessitates precise wavefront control within micro-optical elements.
Existing tunable microlenses, like SmartLenses, offer free-form shaping but have fixed wavefront profiles.
The fixed nature of wavefront profiles limits their application, particularly in aberration correction.

Purpose of the Study:

To achieve precise reconfigurability of wavefront profiles in micro-optics.
To overcome the limitations of fixed wavefront shapes in current tunable micro-lenses.
To demonstrate a novel wavefront shaping approach for advanced optical applications.

Main Methods:

Development of SmartLenses with independently controlled concentric microheaters.
Dynamic shaping of the temperature distribution within a thermo-optical material.
Independent control of Zernike modes for wavefront manipulation.

Main Results:

Demonstrated a bimodal SmartLens capable of simultaneous converging/diverging lens and spherical aberration correction.
Achieved precise reconfigurability of the generated wavefront profile.
Validated the independent control of Zernike modes for dynamic wavefront shaping.

Conclusions:

The novel SmartLens design enables dynamic and reconfigurable wavefront shaping.
This technology paves the way for compact, broadband, and polarization-insensitive wavefront shapers.
Potential applications span diverse fields, including endoscopy and information technology.
