Abstract

The realization of partially coherent Gaussian Schell-model beams with isotropic cross section and anisotropic degree of coherence function is investigated theoretically. An optical system is devised to transform diffused light generated by passing the Gaussian beam of the He-Ne laser thorough a rotating holographic diffuser to the partially coherent Gaussian Schell-model beam with isotropic cross section and anisotropic degree of coherence function. Analytic design equations are formulated and design examples are presented.

등방성 빔 단면과 비등방성 공간 부분 코히어런스 특성을 갖는 가우시안 셀 모델 빔의 구현에 대하여 연구하였다. He-Ne 레이저의 가우시안 빔이 회전하는 홀로그래픽 확산판을 통과하면서 생성된 확산광을 등방성 빔 단면과 비등방성 공간 코히어런스 특성을 갖는 가우시안 셀 모델 빔으로 만드는 광학계를 제안하였다. 광학계의 해석적 설계 방정식을 유도하였고 이를 사용한 설계 예를 제시하였다.
