Abstract:

A computer system and method is presented for dynamic content resolution. The invention comprises one or more source program files and one or more insert statements inserted into the source program files. The insert statements having one or more logical condition statements with one or more logical parameters and one or more state statements. An insert statement parser determines a state of the condition statement, selects one of the state statements associated with the state, and parses the selected state statement into one or more content source indicators. A content source identification process uses one or more of the content source indicators to determine a content source type and one or more access instructions. A content source access process uses the access instructions to access a content source object. A content insertion process replaces the insert statement with the source object in the source program file.

Abstract:

A heterodyne optical spectroscopy system comprises a light source that acts as a local oscillator (LO); a beam splitting component that generates a reference beam from the LO; a signal component that generates a sample signal from a sample; a beam blocker that can turn off the sample signal to generate blank shots; a composite signal detection subsystem that detects a heterodyned signal that is a mix of the sample signal and a portion of the LO; a composite reference detection subsystem synchronized to the signal detection subsystem to detect a portion of the reference beam; and a processor that processes digital signals from the signal detection subsystem and the reference detection subsystem. A very versatile reference scheme is developed to treat different heterodyne spectroscopies in a unified way, which achieves optimal noise suppression.
