  • Coherence adjustable digital holography system
    Patent number: 10775739
    Abstract: Disclosed is a coherence-adjustable digital holography system. More particularly, the coherence-adjustable digital holography system includes a light source part for generating low-interference light; a dispersion part for dispersing the generated light, an adjustment part for adjusting coherence by adjusting a spectrum bandwidth of the light which has passed through the dispersion part; and a detection part for detecting a holographic image of a subject from the adjusted light. In accordance with such a configuration, an interference fringe may be easily obtained through coherence adjustment, whereby the accuracy of a detected holographic image may be improved.
    Type: Grant
