Principles of Fluorescence Spectroscopy
Effects of optical density on the fluorescence intensity of quinine sulfate. The solid
line (——) shows the measured intensities, and the dashed line (– – –) indicates
the corrected intensities, according to equation (2.6) with ODem = 0.
Many times a standard curve between turbidity (optical density) and viable cell
count is made beforehand over the growth period and the number of cells is
ascertained by respective optical density. Although very quick and thus popular,
this ...

Biochemical Engineering and Biotechnology
However, optical density is also a function of cell morphology such as size and
shape, because the amount of transmitted or scattered light depends strongly on
these factors. Consequently, an independent calibration curve is required for
each ...

The Physics of Radiation Therapy
The degree of blackening of the film is measured by determining optical density
with a densitometer. This instrument consists of a light source, a tiny aperture
through which the light is directed, and a light detector (photocell) to measure the
...

The Image Processing Handbook, Fifth Edition
Optical density is denned as I/ I (10.1) . = -log,0|- *n where 7//0 is the fraction of
the incident light that penetrates through the sample without being absorbed or
scattered. If a camera or scanner and its light source are carefully adjusted so
that ...

Intermediate Physics for Medicine and Biology
A plot of optical density vs the logarithm of the relative exposure for a hypothetical
x-ray film. fixed, a process in which the silver halide that was not re- duced is
removed from the emulsion. The result is a film that absorbs visible light where it
...

Biology of the Prokaryotes
The instrument reading is often referred to as "optical density" OD (1 cm cuvette)
measured against a cuvette containing medium only, or as "Klett units" for the
Klett-Summerson photometer. Dense cultures obviously need to be diluted
before ...
