The human eye is an important instrument for gathering information about the world, but it has limitations and obviously varies from person to person. It sees only over a particular range of wavelengths and has a limited ability to distinguish very similar colors. Hyperspectral imaging technologies provide a solution for overcoming these limitations, revealing data that the eye alone cannot capture. This article presents and discusses the new information that hyperspectral imaging brings to unmnanned aerial vehicles.
BaySpec is capable of manufacturing and designing a vast array of gratings, OEM spectrometers, and imaging spectrographs for a range of desired specifications. Other components and devices available from BaySpec include light sources, detectors, cameras, and other high-performance customized solutions.
BaySpec was established when founder William Yang designed and built a grating-based wavelength-division multiplexer-demultiplexer for Bell Laboratories. Many years later, the company’s main priority is still in optical telecommunications, but they have also expanded into the spectroscopy field. This article discusses BaySpec’s business model designed to provide sustainable growth within their diverse markets.
In chemistry, agriculture, and geology near infrared measurements (700-2500 nm) usually are made in transmission and reflection, and they are used to probe the molecular structure and composition of materials. Near infrared is preferred over mid-infrared when measurements need to be made at a distance, or with little or no sample preparation. The challenge is that the resulting spectra are difficult to interpret manually. Interpretation frequently is performed with the aid of multivariate analysis. This type of interpretation makes the choice of instrument characteristics less obvious but the physical and chemical fundamentals do not change. This application note details how optimal results with NIR spectrometers depend more on a good signal-to-noise ratio and less on high spectral resolution.
At Photonics West 2017, Greg Staples focused on selecting different wavelengths for specific applications. Watch the video for wavelength selection guidance for precision agriculture, food sorting, mining, pharmaceutical quality control, and more.
Hyperspectral imaging technology has advanced significantly in the last 50 years, and Greg Staples with Bayspec talked with us for a few minutes at the 2016 SPIE DCS exhibition about how it has changed.
