OFF-AXIS VOLUME HOLOGRAPHIC OPTICAL ELEMENTS FOR INFRARED
Annotation
Peculiarities of recording of off-axis volume holographic optical element (HOE) used as a one-component lens for near infrared are considered. It is shown experimentally that aberrations of reference and object waves, appearing at the stage of the HOE recording, are more than an order of magnitude smaller than the laser wavelength. Measured values of transverse aberration HOE are close to calculated data. It is noted that increase in signal-to-noise ratio of an off-axis volume HOE extends detection range of infrared radiation sources.
