C2LI: Enhancing Structural Color Sensing and Imaging via Complementary Color Laser Illumination

Advanced Optical Materials, EarlyView.
This article introduces complementary color laser illumination (C2LI) and demonstrates it to be an effective approach for engaging the visual system to enhance perceptual sensitivity and chromatic contrast. This enhances a human user's ability to detect subtle differences in sample or medium characteristics, enabling novel applications in colorimetric ...

Somewhere over the rainbow: How to make effective use of colors in meteorological visualizations [PDF]

, 2013
Results of many atmospheric science applications are processed graphically using colors to encode certain parts of the information. Colors should (1) allow humans to process more information, (2) guide the viewer to the most important information, (3 ...

The Star Formation History of NGC 1705: a Post-Starburst Galaxy on the Verge of Activity

, 2003
We infer the star formation history in different regions of the blue compact dwarf NGC 1705 by comparing synthetic color-magnitude diagrams with HST optical and near-infrared photometry.

Design Method of Time‐Multiplexed Ultrashort Throw Ratio Projection System with Low Distortion and Uniform Resolution

Advanced Photonics Research, EarlyView.
This work develops an ultrashort throw ratio (UTR) laser projection system using time‐multiplexed micro electro mechanical systems scanning. Trapezoidal distortion via vertical laser incidence control is eliminated and a systematic design method integrating a miniaturized catadioptric objective that maintains uniform optical étendue is proposed.

Design of a Bilayer Metalens for Red, Green, and Blue‐Achromatic Imaging with Wide Field of View

Advanced Photonics Research, EarlyView.
Herein, an RGB‐achromatic bilayer metalens with a wide 80‐degree field‐of‐view and a high 0.65 numerical aperture is presented. Using silicon nitride meta‐atoms, it maintains consistent focal lengths for red, green, and blue light, even at oblique angles.

An AI‐Enabled All‐In‐One Visual, Proximity, and Tactile Perception Multimodal Sensor

Advanced Robotics Research, EarlyView.
Targeting integrated multimodal perception of robots, an AI‐enabled all‐in‐one multimodal sensor is proposed. This sensor is capable of perceiving three types of modalities, including vision, proximity, and tactility. By toggling an ultraviolet light and adjusting the camera focus, it switches smoothly between multiple perceptual modalities, enabling ...
