PhenoTron® Dual-Mode Intelligent LED Cultivation & Hyperspectral Imaging Platform

Overview

The PhenoTron® Dual-Mode Intelligent LED Cultivation & Hyperspectral Imaging Platform is a fully integrated, research-grade phenotyping system engineered for high-throughput, non-invasive, and quantitative plant physiological and biochemical characterization under controlled environmental conditions. Built upon EcolabTech’s proprietary dual-layer XYZ scanning architecture and multi-spectral illumination control, the platform combines precision LED-based photobiological cultivation with synchronized hyperspectral imaging (400–1000 nm), optional UV-MCF fluorescence imaging, SWIR hyperspectral imaging (900–1700 nm), chlorophyll fluorescence imaging (FluorCam), and thermal-RGB imaging — all within a single, modular enclosure. Its core measurement principles include reflectance-based spectral unmixing, pulse-amplitude modulated (PAM) chlorophyll fluorescence kinetics, UV-excited biological fluorescence emission profiling, and radiometric thermal mapping. Designed for reproducible experimental workflows in plant science, the system supports GLP-aligned data acquisition, time-series phenotypic monitoring, and scalable digital trait extraction across diverse biological scales — from seedlings and tissue cultures to potted adult plants.

Key Features

• Dual-layer independent cultivation and imaging platform: Upper and lower layers operate with separate environmental control, enabling parallel experiments or staggered growth-stage analysis.
• Multi-channel intelligent LED lighting system: Configurable RGB + far-red, RGB + UV + far-red, or custom spectral combinations (4–7 channels); 255-level intensity resolution per channel; preloaded spectral recipes for diurnal cycles, forest understory, overcast conditions, and photomorphogenic treatments.
• Full-spectrum white illumination: Nine diffuse halogen lamps (400–1000 nm), linearly dimmable 0–100%, optimized for uniform irradiance and color fidelity in RGB documentation.
• 400–1000 nm push-broom hyperspectral imager: 224 spectral bands (binning ×2), 5.5 nm FWHM spectral resolution, 1024-pixel spatial resolution, 330 FPS frame rate (up to 9900 lines/sec), SNR 420:1; supports region-of-interest band selection to minimize data volume without compromising analytical specificity.
• Optional UV-MCF fluorescence imaging module: Enables simultaneous acquisition of blue-green fluorescence (BGF, F440/F520), red/far-red chlorophyll fluorescence (F690/F740), and ratio-based indices (e.g., F735/F700 for chlorophyll quantification; F730–740/F680–690 for chronic stress assessment).
• Optional SWIR hyperspectral imaging (900–1700 nm): 224 bands, 8 nm FWHM, 640-pixel spatial resolution, 670 FPS (15,000 lines/sec), SNR 1000:1; calibrated for nitrogen content estimation, water status mapping, and drought stress phenotyping.
• Optional FluorCam chlorophyll fluorescence imaging: High-sensitivity CCD sensor (720 × 560 px), 50 fps, three-color excitation LEDs (blue/red/far-red), programmable actinic light (0–1000 µmol·m⁻²·s⁻¹) and saturating pulses (3900 µmol·m⁻²·s⁻¹); automated execution of Fv/Fm, Kautsky induction, NPQ, Y(II), ETR, and >50 derived fluorescence parameters.
• Optional Thermo-RGB imaging: Uncooled microbolometer (7.5–13.5 µm), 10× optical zoom, real-time temperature overlay on RGB imagery; supports max/min/center-point temperature logging, isotherm delineation, and thermal anomaly alerts.
• Time-aware automation: Integrated GPS and NTP synchronization enable automatic local time and weather data retrieval; LED intensity and spectral composition dynamically adjust to simulate realistic diurnal and meteorological variability.

Sample Compatibility & Compliance

The PhenoTron® Dual-Mode accommodates a wide range of plant specimens including but not limited to Arabidopsis thaliana rosettes, cereal seedlings, horticultural crops (tomato, lettuce, pepper), medicinal herbs, tissue culture plates, and clonal propagation trays. Its open-access scanning volume (180 × 80 cm per layer, Z-axis adjustable) allows flexible positioning of pots, Petri dishes, or multi-well plates. The platform complies with ISO 22093:2021 (Plant phenotyping — General requirements for instrumentation), adheres to ASTM E2594-22 guidelines for spectral imaging validation, and supports audit-ready data provenance through embedded timestamping, metadata tagging (EXIF + custom JSON schema), and optional 21 CFR Part 11-compliant user access logs and electronic signatures when deployed in regulated breeding or GxP environments.

Software & Data Management

The system operates via EcolabTech’s Phenolytix™ software suite — a Python-based, cross-platform application supporting Windows and Linux. Phenolytix™ provides unified control of hardware modules, real-time preview of spectral cubes and fluorescence kinetics, batch processing pipelines for reflectance normalization (e.g., dark/light reference correction), spectral index computation (NDVI, PRI, MCARI, WI, etc.), PCA-based feature reduction, and machine-learning-ready export (HDF5, ENVI .hdr/.img, GeoTIFF). All raw and processed datasets are stored with FAIR principles (Findable, Accessible, Interoperable, Reusable) in hierarchical directory structures, with built-in DICOM-like metadata headers. Export options include CSV tables of pixel-averaged spectra, ROI-based trait matrices, animated GIFs of time-series fluorescence dynamics, and georeferenced orthomosaics for canopy-level analysis. Remote monitoring and scheduled acquisition are supported via RESTful API and MQTT integration.

Applications

• Genetic resource evaluation and germplasm screening under standardized photoperiodic regimes
• Longitudinal phenotyping across developmental stages: germination, vegetative expansion, flowering, senescence
• Abiotic and biotic stress phenotyping: drought, salinity, nutrient deficiency, pathogen infection
• Photosynthetic efficiency mapping via chlorophyll fluorescence parameters (Fv/Fm, ΦPSII, NPQ)
• Secondary metabolite profiling: anthocyanin index (AnthoIndex), flavonol index (FlavIndex), nitrogen balance index (NBI)
• Vertical farming R&D: spectral optimization for yield, quality, and energy efficiency
• Digital twin development for crop modeling and AI-driven trait prediction
• Regulatory-compliant variety testing per OECD TG 209 or UPOV guidelines
