Reflectance to Status A Density; How to convert?

AI Thread Summary
To convert spectral reflectance data (%R in 10nm increments) to Status A density, one must first ensure the data is accurately transformed into RGB format. This process involves using calibration data from reflectance standards to check the accuracy of reflection densitometers that measure Status A density in various color channels (V, R, G, B). The conversion is complex but can be achieved by referencing established methodologies, such as those outlined in relevant literature. Additionally, the transformation from spectral data to density requires careful consideration of the spectral response of the densitometers. Proper execution of these steps will ensure accurate density readings.

I have calibration data for some 0/45 reflectance standards which is in spectral format of %R in 10nm increments. I need to check the accuracy of reflection densitometers which read Status A density (V,R,G,B).
What is the proper way to convert the spectral reflectances to density?
Thanks,
GR

It doesn't look very compact, but it seems to be a well-posed problem:

http://books.google.com/books?id=CzAbJrLin_AC&pg=PA393&lpg=PA393&dq=%22Status+A+density%22&source=bl&ots=32xXUFXt5b&sig=RW8FvhaTqO4ZVcIf51y7EqN5Y9Q&hl=en&ei=PBDJScecGoK8M7qcxecD&sa=X&oi=book_result&resnum=3&ct=result

(Page 393). You will also have to convert your spectral data into an (RGB) format, which is also not simple but well-posed.

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
