The microphotometer. To determine the OTF, the microphotometer is normally
used in measuring the transmittance or density distribution in the image. The
most important characteristic of the microphotometer is its OTF, because the
measured ...

The Optical Transfer Function of Imaging Systems
The main advantage of this type of microphotometer, compared with the
mechanically scanned arrangement described earlier, is that it is faster. This is
not only because an array can be electronically scanned faster than a
microphotometer ...

Evans reports that the microphotometer at the Sacramento Peak Observatory is
now in the final stages of development. This microphotometer yields an output
directly in either intensity or log intensity. The basic electronic circuit is similar to
that ...

This instrument allowed direct registration of the line intensities and thus avoided
tedious conversion of the microphotometer record by means of a calibration
curve. The thermoelectric current from a tube-shaped Moll microphotometer in
the ...

The finite slit width used in the microphotometer limits the resolving power of this
instrument, but the resolving power of the microphotometer under the conditions
actually used is of a higher order than that of the original spectrograph; one ...
