Visible and Near Infrared (VNIR) Hyperspectral Imager

This VNIR imager is a line-scan based instrument that consists of a CCD camera (a, ICL-B1410, Imperx Inc., Boca Raton, FL), spectrograph (b, ImSpector V10E, Specim, Oulu, Finland), and optical lens (c, XNP 14/17-0503B, Schneider Optics, Hauppage, NY ). It covers a range from 400nm to 1000nm and provides high spatial or spectral resolution.

 Longer-wavelength Near Infrared (LNIR) Hyperspectral Imager

The spectral imager is assembled using off-the-shelf commercial products: an LCTF (c, Model Varispec LNIR 20-HC-20, Cambridge Research & Instrumentation, Cambridge, MA, USA), an InGaAs camera (a, Model SU320KTS-1.7RT, Goodrich, Sensors Unlimited, Inc, Princeton, NJ, USA), and a lens (b, Model SOLO 50, Goodrich, Sensors Unlimited, Inc, Princeton, NJ, USA). It covers a range from 900nm to 1700nm.

3-D Imaging:

Microsoft Kinect sensor

The Microsoft Kinect is a light-coding based 3-D scanner. It consists of an infrared laser projector and a monochrome CMOS sensor, which provides RGB data with 3D information under any ambient light condition. Typically, it is more suitable for indoor applications.

MESA SR4500

The SR4500 is an optical imaging system that provides real time distance data at video frame rates. Measurements are obtained using the time-of-flight (TOF) principle out to 9 meters with a 69×55 degree Field of View.

Motic BA410 Trinocular

The BA410 provides the best image quality in the demanding cytology, pathology, and histology fields from amateur to professional levels. The improved CCIS Optical system includes a variety of contrast techniques like fluorescence, dark field, and polarization as well as an improved phase contrast: one condenser covers both positive and negative phase contrast lenses.

Thermal Imaging:

FLIR T440 Camera

The FLIR T440 is fast and easy to use to accurately detect the temperature of objects. It provides three resolution choices: 320 Ч 240, 480 Ч 360, and 640 Ч 480, and its sensitivity is as fine as <0.035°C for subtler thermal patterns and reaches up to 2,000°C for measuring the hottest target.

Cyranose 320

The Cyranose utilizes an array of 32 sensors to detect aromas. An air sample is drawn over the sensors. Then the unit’s microprocessor analyzes the resistance across the sensor array and uses the resulting data to create a unique “smellprint.”

This handheld unit can be run either on AC or battery power. Its portability and small size make it ideal for sampling volatiles in the field. It has been applied in the Food and Fiber Sensing Lab to detect fungal and bacterial diseases in onions.

zNose 4200

The zNose is an Ultra-Fast GC Analyzer. It is designed to detect vapors including volatile organic compounds and semi-volatile compounds.

An air sample is drawn into an adsorbent trap; the trap is then heated, and the compounds are transported by a carrier gas (He) to a capillary column. The compounds are separated and then deposited onto the SAW crystal. The SAW (Surface Acoustic Wave) crystal detects compounds as they contact the crystal after exiting the column. The compound’s mass affects the frequency at which the crystal resonates. The frequency indicates what compound is being sampled.

The zNose has been applied in the FFS Lab to detect damage to cotton bolls caused by feeding stinkbugs. In addition, it has also been used to detect fungal disease in blueberries and onions.

Instrument Prototyping and Testing:

Our lab has the ability to make prototypes for electronic instruments and devices. It is currently equipped with all necessary equipment related to electronics including oscilloscopes, power supplies and function generators. We have NI data loggers to test the prototype. In addition, we have a 3D printer which can turn your design into reality immediately.
