基于多焦点光子筛阵列的同轴相移全息技术
|
摘要
设计出不同相移步长的多焦点光子筛阵列,利用相移数字全息术对USAF1951分辨率板进行成像,在光学波段验证了光子筛阵列的相移功能。实验结果表明,多焦点光子筛阵列在不同相移步长下均可消除零级像和共轭像,系统分辨率均与理论预期结果一致。作为一种振幅型衍射透镜,多焦点光子筛阵列在X射线全息术和生物细胞显微等领域有着广阔的应用前景。
Multi-focal photon-sieve arrays with different phase shift steps are designed. The imaging of the USAF1951 resolution board is obtained by phase-shifting digital holography, and the phase-shifting function of the photon-sieve array is verified in optical waveband. The experimental results shows that multi-focal photon-sieve arrays can eliminate zero-order image and conjugate image under different phase shift steps, and the system resolution is consistent with theoretical expected result. As a kind of amplitude diffractive lens, the multi-focal photon-sieve array has a wide application prospect in the fields of X-ray holography and biological cell microscopy.
