Abstract Digital holographic microscopy (DHM) is actively investigated in the field of bio-imaging as a technique for quantitative phase microscopy. During recent years, the digital holographic technique for enhancing the spatial resolution using speckle patterns has been reported by several research groups. In this study, we have enhanced the spatial resolution and extended the measurement range of the shape measurement by applying a two-wavelength method to DHM using speckle illuminations.

使用散斑照明的双波长数字全息显微镜

摘要 数字全息显微镜 (DHM) 作为定量相位显微镜技术在生物成像领域得到了积极的研究。近年来，一些研究小组已经报道了使用散斑图案来提高空间分辨率的数字全息技术。在这项研究中，我们通过使用散斑照明将双波长方法应用于 DHM，提高了空间分辨率并扩展了形状测量的测量范围。
