Join ASD at The 2017 SPIE Defense + Commercial Sensing Conference

March 30, 2017

The leading global sensing and imaging event heads to Anaheim – and ASD will be there. We will be joining other professionals at The 2017 SPIE Defense + Commercial Sensing conference April 11 – 13 in Anaheim, California to demonstrate the use of the the FieldSpec® 4 Standard-Res portable spectroradiometer and the FieldSpec® HandHeld 2 hand-held spectroradiometer.

The Importance of Calibrating Your Remote Sensing Imagery

March 28, 2017

Author:  Susan Parks, ASD Remote Sensing Segment Manager

Most people using satellite or aerial imagery understand the importance of geometric calibration; you need to tie the pixels in the imagery to the corresponding coordinate locations on the earth so that you can use the imagery in mapping applications. This is also important for analyses such as change detection.

However, there is another type of calibration that you should be doing on your optical remote sensing imagery to ensure that you are getting high quality and useful results from your images. Accurate radiometric calibration is a critical component for successful imagery analysis.

Join ASD at the AAPG/ACE 2017 Conference

March 23, 2017

Top mine operations around the world already trust ASD’s TerraSpec® line of mining instruments for their critical mineral analysis measurements. Realizing potential applications of dispersive NIR in the petroleum industry, ASD is joining 6,800 professionals from more than 72 countries at the AAPG/ ACE 2017 conference this April 2 – 5 in Houston, Texas.

Material Measurement with NIR

March 21, 2017

Author:  Dan Shiley, Manager ASD SummitCAL Solutions Team

We are often asked questions like, “how do I measure my product using ASD NIR?” Of course my standard answer is, “it depends”. Since so much depends on the assumptions and conditions, I thought it would be useful to try to help clarify some of the things that proper material measurement depends upon.

Calibrating with a White Reference for a Baseline

March 16, 2017

Author:  Michaela Kastanek, ASD Chemometric Specialist

In the world of NIR spectroscopy the words “calibration”, “white reference”, and “baseline” are often used interchangeably. Essentially these are all describing the same thing – the use of a reference material that has essentially 100% reflectance to calibrate the instrument to create a reflectance spectrum. But that raises a few questions. What is this white reference? Why is it needed? And is it truly 100% reflective?

What is it?

ASD field and lab based spectrometers all use a sintered polytetrafluoroethylene material better known by its commercial name, Spectralon, as a white reference. Produced by LabSphere and sold with all ASD instruments, Spectralon has a few unique qualities that make it an ideal material for optimizing ASD spectrometers. It comes in large and small round disks and square flat panels. It is rugged enough for field work and relatively easy to clean, and it is thermally and chemically stable.

How to Make Mining Less Expensive

March 07, 2017

How many hours are you losing trying to identify minerals?

Thanks to the mineralogical data provided by the TerraSpec® Halo mineral identifier, mine geologists have access to real-time information vital to reducing costs and improving ore recovery and mining revenue.

The TerraSpec Halo is a portable NIR mineral identification instrument; it is an all-in-one analysis system that allows you to immediately identify alteration minerals via non-destructive contact measurement. This ASD full-range (350-2500 nm) NIR spectrometer is making a lot of press lately in the exploration and production geology market as an important tool in the process of field mapping and sampling at many mine sites.

Measure Accurate Field Reflectance Spectra Under Variable Atmospheric Conditions

February 28, 2017

Do you get frustrated while waiting for the perfect day to collect field spectra?

Oftentimes when taking field measurements, one day it is sunny and the next day it is cloudy. The problem is that this fluctuation throws off your data. In fact, rapidly changing atmospheric conditions poses one of the greatest obstacles to the collection of accurate field-collected reflectance spectra using solar illumination.

Seeing the Unseen:  The Value of Spectral Satellite Imagery

February 24, 2017

As satellite imagery and remote sensing become more and more popular in the realm of earth observation, it can still be confusing to determine how to use or interpret this imagery to solve real problems.

Discover Materials Characterization Solutions from ASD at PITTCON 2017

February 22, 2017

Raw material analysis is critical for a variety of industries, including those represented at the upcoming PITTCON Conference and Expo this March 5 – 9, 2017 in Chicago, Illinois. As many of you know, ensuring the quality of incoming raw materials is a critical first step in most industrial processes. Identification of non-conforming materials prior to processing can improve operational performance and save valuable time. Quality control is equally important during the manufacturing process to produce better quality products which leads to increased profitability.  

ASD at PDAC 2017 - How the TerraSpec® 4 and the TerraSpec Halo mineral identifier benefit an exploration program

February 16, 2017

Identifying confusing alteration minerals is critical to speed exploration efforts and for accurate resource evaluation. However, many similar-looking alteration minerals that can help you vector faster to your ore body are very tough to differentiate in the field without time consuming lab work.
