In addition to CALC_LENS, ALSSP contains a variety of utility programs
designed to help in the design and analysis of lens systems. Complete descriptions of
these are included in the
ALSSP User's Guide.
Included are programs to automate the creation of lens systems and set up the
associated calculations, to plot
pressure fields and beam patterns and annotate those plots, and to simplify the process
of extracting data about lens systems from the stored results. Brief descriptions of the
most important utility programs are given in Table 4.
-
ANNOTATE
-
Adds annotation (text) to a plot.
-
CONCAT_RESULTS
-
Assembles multiple source position results into a beam
pattern. The resulting beam pattern is the response of a
fixed transducer element to a moving point source.
-
FOCI_CIRC
-
Assembles pre-calculated focal points into a focal
trajectory.
-
GENERATE_SYSTEM
-
Converts a BEAM THREE
1 OPTIC file to ALSSP
parameter files for an array of source positions.
-
GET_LOG
-
Assembles the results of multiple focal point searches
into a single array.
-
KLEGEND
-
Adds a legend to a plot.
-
KPLOT
-
Displays pressure fields and beam patterns. Also finds
3 dB points, sidelobe heights and positions, and
maximum pressure points and values.
-
MAKE_BEAMS
-
Generates parameter files to calculate the response of
an element at a single point to an array of source
positions.
-
MAKE_BEAMS1
-
Generates parameter files to calculate the beam pattern
for a system by moving the transducer element along
the focal trajectory.
-
MAKE_BEAMS2
-
Creates parameter files to calculate beam patterns.
-
MAKE_LINE_MAX
-
Generates a parameter file to find the maximum
response of an element along a line through a lens
system's pressure field.
-
MAKE_MAX_REGION
-
Generates a parameter file to find the maximum
response of an element within a region of space.
-
MAKE_VOLUME
-
Generates a parameter file to calculate the pressure
field of a lens system within a region of space.
-
MAN
-
Gives a brief summary of an ALSSP routine.
