Project Description:

A hyperspectral VIS-NIR (Visible to near infrared wavelengths) solar CCD spectrometer to be used to analyze forest health. Composed of a series of optics to focus and isolate individual wavelengths for detection enclosed in a polycarbonate 3D printed enclosure. The final design incorporates a field of view of 45 degrees and allows for focused light in the wavelength range of 400-1000nm. Weighing just under 3 lbs and being smaller than 8x8x5in, this allows the final product to be mounted on a UAV for aerial data collection. This device is capable of operating in standard weather and temperatures including heavy rain/snow as well as an operating temperature range of 0-50 °C. The enclosure protects the internal components (both optical and electrical) from liquids and dust. Design softwares used include Zemax, Onshape, and MATLAB.
