UV/VIS/NIR reflectance
spectroscopy satisfies the
researchers need for speed
and precision in the estimation
of key forest canopy
characteristics. SPECTRAL
EVOLUTION
spectroradiometers include
pull-down menu access to
more than 19 vegetation
indices.
Studying forest canopies is an ideal application for field
spectroradiometers. Examples of research projects in evaluating
  • Environmental research using leaf reflectance
  • Canopy architecture and nutrient concentration
  • Discrimination and identification of different plant species
    within a heterogeneous canopy for species mapping
  • Nitrogen cycling and whole canopy photosynthetic capacity
  • Herb and moss biomass studies in closed canopy
    environments
  • Leaf morphology, leaf distribution, leaf allocation, leaf
    orientation
  • Forest canopy moisture content and forest fire risk
  • Measurement of vegetation for chlorophyll, lignin,
    cellulose, hemi-cellulose and nitrogen

Because it is non-destructive, spectroscopy is a popular tool for
remote sensing applications like canopy research. Measurement
and analysis won't change or affect the sample in any way, no
chemicals or hazardous materials are used, measurements are
very fast, and several different vegetation characteristics can be
gleaned from a single scan. And, SPECTRAL EVOLUTION'S
portable agricultural spectrometers and spectroradiometers are
designed for easy use in the field, with rugged construction,
light weight, and reliable operation.

Spectral signatures of materials are defined by reflectance or
absorption as a function of wavelength. NIR spectroscopy
measures the reflectance of infrared light wavelengths for
samples and the shapes of the leaf/vegetation spectra
correspond to important characteristics, including species
identification, health, stress, infestation, pollution, climate
change, drought, fertilization, and more  - all from a single scan.

The spectra collected can be analyzed using a range of third
party analysis and chemometric packages, including GRAMS, The
Spectral Geologist (TSG), and others.  SPECTRAL EVOLUTION'S
DARWin SP Data Acquisition software saves your spectra as ASCII
files for use with analysis software.

In addition for the PSR+ 3500 and SR-3500 full range
spectroradiometers, DARWin SP includes optional
EZ-ID sample
identification software that matches a target spectra against a
library of known spectra. If you want to build a custom library, EZ-
ID offers the fast and easy-to-use
Custom Library Builder module.
This module allows researchers to quickly and easily build
custom libraries of known samples for comparison with unknown
target samples.

Spectroradiometers for forest canopy research include:
  • PSR+ 3500 - 350-2500nm spectral range
  • RS-3500 remote sensing bundle - spectroradiometer and
    accessories
  • PSR-1100-F - handheld unit with built-in keypad and LCD
    display
  • UDS-1100 - simultaneous upwelling/downwelling
    measurement

Screen shot of Getac PS236 handheld PDA -  True handheld convenience for field work or remote sensing!- Every SPECTRAL EVOLUTION handheld spectrometer can be controlled via Bluetooth connection by a Windows-enabled laptop or ruggedized personal digital assistant (PDA) running Microsoft Windows Mobile. SPECTRAL EVOLUTION offers a PDA compatible version of its DARWin SP Data Acquisition Package that permits rapid analysis of mobile data and can be used to trigger data collection remotely.
True handheld convenience for field work or remote sensing!
Every SPECTRAL EVOLUTION handheld spectrometer can be
controlled with a  laptop or ruggedized personal digital
assistant (PDA). its DARWin SP Data Acquisition Package that
permits rapid analysis of mobile data and can be used to
trigger data collection remotely. All SPECTRAL EVOLUTION
handheld portable spectrometers also feature fingertip
controls and an to 500 spectra, so the unit can even be
operated without a computer or PDA!  SPECTRAL
EVOLUTION offers the GETAC PS336 PDA preloaded with all
EVOLUTION Spectrometers. The GETAC can be used to tag
spectra with GPS readings, photos (with its built-in 5
megapixel camera) and voice notes with its built in
microphone. In this image, the PS336 was used to take a leaf
scan along with a photo of the leaf. The extra bright 480x640
display can even be viewed in direct sunlight!
