Lambda Hyperspectral Imaging Systems Lambda-Nir
The Lambda hyperspectral imaging system uses gradient coating without a conventional grating-based spectral module to image targets continuously in tens or hundreds of bands across its spectral coverage. Spatial images and spectral information are acquired together. The system includes an area-array detector, power supply, motion control, and data acquisition modules. Applications include crop nitrogen, chlorophyll, biomass, disease, and soil fertility monitoring for precision agriculture; real-time monitoring of more than 10 water-quality indicators, including total phosphorus, total nitrogen, chlorophyll a, suspended solids, PH, chemical oxygen demand, ammonia nitrogen, and dissolved oxygen; sorting PE, PP, PS, PC, PA, PU, PEL, PVC, POM, ABS, and other plastics; banknote authentication by hyperspectral images, spectral analysis, and texture analysis; and identifying tree species and distributions of leaf agricultural indicators using leaves in an indoor dark-box system. Source clinical example: tongue-coating water-distribution images for K0074, K0082, and K0090; K0074 has higher water content and more saliva, and the source judges the patient listless, describing this as a manifestation of chronic kidney disease. Other uses include shredded-tobacco biochemical analysis, type identification, and impurity detection. Supplemental source examples: reflectance curves for crops under different nitrogen treatments; plastic sorting; tree species, biomass, and leaf nitrogen monitoring; fruit dark/white spots, bruising, ripeness, and sugar-content inspection; rapid fruit-damage localization; tongue-coating, wisdom-tooth, skin, and mole inspection; facial mole identification; tobacco composition, type, and impurity inspection.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
