Incoherent beam combining of parallel beams with optical path compensation using real time holography |
摘要 |
A system for path compensation of multiple incoherent optical beams incorporates an optical element combining a plurality of incoherent beams to an aperture by angle using carrier frequency tilt fringes. An illumination laser is employed for reflection of an illumination beam from a target. An interferometer receives a sample of the reflected illumination beam reflected from the target and provides interference fringes. A spatial light modulator receives the interference fringes and generates a real time hologram. Relay optics are employed for transmitting the combined plurality of incoherent beams to the SLM and receiving a diffraction corrected full aperture compensated combined beam for emission to the far field. |
