Inline scanning holography system for phosphor and transmitter

An inline scanning holography system comprising:

• a linear polarization direction converter configured to provide a linearly polarized beam by changing a polarization direction with phase-delaying the linearly polarized beam incident from an outside;
• a signal generation unit configured to generate a phase modulation signal for varying a phase delay value with time and apply the phase modulation signal to the linear polarization direction converter;
• a collimator configured to expand the linearly polarized beam passing through the linear polarization direction converter;
• a polarization sensitive lens configured to receive the expanded linearly polarized beam from collimator and configured to generate a first spherical wave of right-handed circular polarized light having a negative focal length and a second spherical wave of left-handed circular polarized light having a positive focal length,
• wherein the collimator is located between the linear polarization director converter and the polarization sensitive lens, wherein the linear polarization direction converter is located at a front end of the polarization sensitive lens;
• a polarizer configured to pass only a beam component in a predetermined polarization direction therethrough among components of the generated first and second spherical waves;
• a scanning unit for scanning a phosphor that is a fluorescence object by using an interference beam generated between the first and second spherical waves passing through the polarizer;
• and
• a first photodetector configured to detect a fluorescent beam diverged from the phosphor.
