Integrating Sphere Functionality: The Scatter Transmission Measurement
ثبت نشده
چکیده
The integrating sphere is a simple, yet often misunderstood spectrophotometer accessory for measuring optical radiation. The function of an integrating sphere is to spatially integrate radiant flux in scatter transmission and diffuse reflectance sample measurements. Before one can optimize a sphere design for a particular application, it is important to understand how the integrating sphere works. How light passes through the sphere begins with a discussion of diffuse reflecting surfaces. From this, the radiance of the inner surface of an integrating sphere is derived and discussed.

Minimising contributions from scattering in infrared spectra by means of an integrating sphere.
Mid-infrared spectra of biological matter such as tissues or microbial and eukaryotic cells measured in a transmission-type optical setup frequently show strongly distorted line shapes which arise from mixing of absorption and scattering contributions. Scattering-associated distorted line shapes may considerably complicate the analysis and interpretation of the infrared spectra and large effort...
متن کاملImpact of Particle Aggregated Microbes on UV Disinfection. II: Proper Absorbance Measurement for UV Fluence
Ultraviolet UV absorbance measurements are subject to significant error using a standard spectrophotometer when particles or aggregates that scatter light are present. True UV absorbance for highly turbid waters should be measured using integrating sphere IS spectrophotometry that allows the collection of reflected and transmitted radiation simultaneously. This is especially important when the ...

متن کاملCalculation of the Scattered Radiation Profile in 64 Slice CT Scanners Using Experimental Measurement
Introduction: One of the most important parameters in x-ray CT imaging is the noise induced by detected scattered radiation. The detected scattered radiation is completely dependent on the scanner geometry as well as size, shape and material of the scanned object. The magnitude and spatial distribution of the scattered radiation in x-ray CT should be quantified for development of robust scatter...
