Lensless imaging through phase-conjugated backscattering in SF(6)

A phase-conjugate mirror based on stimulated Brillouin scattering in gaseous SF(6) at 248 nm was used for pattern transfer. We measured the pressure dependence of backscattering efficiency of the Brillouin mirror, which approached 40% reflectivity and was limited by the onset of gas breakdown. Measu...

Zusammenfassung:A phase-conjugate mirror based on stimulated Brillouin scattering in gaseous SF(6) at 248 nm was used for pattern transfer. We measured the pressure dependence of backscattering efficiency of the Brillouin mirror, which approached 40% reflectivity and was limited by the onset of gas breakdown. Measurement of the image contrast ratio showed high statistical fluctuation due to the threshold behavior of Brillouin scattering.
