PSIOS
(Phase Stepped Images Observed Simultaneously) splits the incident beam into
four independent images, each of which is phase-stepped and captured by a
separate camera. |
DIOS
(Dynamic Images Observed Simultaneously) as for PSIOS but only a single
camera is used, allowing dynamic or transient events to be monitored. |
Poleidoscope
uses co-linear beam splitting with four phase-steps and data capture with a
single camera. A solid state
polariscope available from Stressphotonics. |
