20140247442 | SPECTRORADIOMETER DEVICE AND APPLICATIONS OF SAME - A light weight, portable spectroradiometer device has an optical system that directs incoming wavelengths of light to impinge upon a three-dimensional sensor comprised of a linear variable filter in direct contact with a photodiode array. The linear variable filter can be a specific band pass filter coating that has been geometrically wedged in one direction. The incoming wavelengths of light are transmitted through the three-dimensional sensor and differentiated into the pixels to be further processed into digital signals. A standard light source, either external or internal to the device, and emitting specified intensities over wavelengths may also be used to calibrate the spectroradiometer device, and samples of light with unknown intensities may be compared to the standard light source. The compact geometry of the optical system and sensor allows the device to be a compact, light weight three-dimensional spectroradiometer containing no moving parts and having a rapid measurement time. | 09-04-2014 |
20080265146 | INTEGRATED SENSING MODULE FOR HANDHELD SPECTRAL MEASUREMENTS - An integrated spectral sensing engine featuring energy sources and detectors within a single package includes sample interfacing optics and acquisition and processing electronics. The miniaturized sensor is optimized for specific laboratory and field-based measurements by integration into a handheld format. Design and fabrication components support high volume manufacturing. Spectral selectivity is provided by either continuous variable optical filters or filter matrix devices. The sensor's response covers the range from 200 nm to 25 μm based on various solid-state detectors. The wavelength range can be extended by the use of filter-matrix devices. Measurement modes include transmittance/absorbance, turbidity (light scattering) and fluorescence (emission). On board data processing includes raw data acquisition, data massaging and the output of computed results. Sensor applications include water and environmental, food and beverage, chemical and petroleum, and medical analyses. These can be expanded into various field and consumer-based applications. | 10-30-2008 |
