Off-Axis Wavefront Measurement System for Aspheres Based on a Reflective SLM

Reflective SLMs are gaining increasing attention for aspherical surface testing due to their dynamic adjustability, fast operation, and high optical efficiency, offering clear advantages over costly CGH methods. This paper presents a wavefront measurement system that avoids the n...

Development of a Milli-Kelvin Thermostatic Bath for High-Precision Temperature Sensor Calibration

For most temperature sensors, measurement traceability must be established via a comparison method within a thermostatic environment. To address the limitations of domestic constant temperature baths in meeting the calibration requirements for high-precision temperature sensors i...

Photonic-crystal hydraulic manometry quantifies epithelial basal compression for rapid, label-free functional screening

Polarized epithelia integrate barrier sealing, vectorial ion-water transport, and cytoskeletal mechanics, yet scalable assays that report this coupled functional state in real time remain limited. Here, we introduce photonic-crystal hydraulic manometry (PCHM), which quantifies ou...

Height-Based Stratification in Greenhouse Harvesting Robotics: A Review from Ground-Level to High-Wire Crops

Labor shortages and the push for higher greenhouse efficiency have accelerated interest in automated harvesting. However, the development of a universal harvesting robot has been constrained by large variations in crop architecture, especially plant height. In this review, a heig...

Boosting NIR Emissions and Thermal Resistance in Cr3+-Doped MgGa2O4 Semiconductor Microcrystals by Energy Transfer for Smart Detection

High-radiant-intensity broadband near-infrared (NIR) emitters are highly desirable for nondestructive testing, night-vision imaging, and information encryption. However, the exploration of phosphors that possess both high luminous efficiency and outstanding thermal stability cont...

Sensitivity analysis of distance accuracy test for six-degree-of-freedom serial industrial robots

Purpose In recent years, industrial robot technologies and applications have developed rapidly, making it necessary to improve their performance testing methods. This paper aims to investigate the sensitivity of the distance accuracy test method specified in ISO 9283:1998 (Manipu...

Vision-Based Counting of Horticultural Seeds Using ViT-UNet Density Regression for Post-Harvest Quality Assessment

Reliable counting of horticultural seeds is important for seed grading, batch consistency assessment, packaging, sowing-rate control, and post-harvest quality evaluation. Manual counting is labor-intensive, whereas conventional image-processing methods can be sensitive to seed ad...
