Quantitative phase imaging (QPI) has emerged as method especially for investigating biological specimen. However, conventional methods often suffer from shortcomings in image quality, such as the twin image artifact of inline holography. The presented compact 3D sensing system utilizes a novel computational framework for QPI from single intensity images. The reported system offers accurate and efficient 3D profiling, overcoming the limitations of conventional inline holography approaches. This paradigm shift is promising for biomedical imaging, and material analysis.
This review article analyzes the current state of the 2D and 3D deformable displays and discusses the technological challenges to be achieved for practical uses and industrial commercialization.
Non-ideal achromatic flat lenses for a large-scale diameter up to 10 mm were experimentally realized and reported recently, which demonstrated a broad working bandwidth from 400 to 1100 nm.
Three-dimensional photoacoustic tomography synchronized with an electrocardiogram provides highly resolved images of a beating heart with optical absorption contrast and enables investigation of cardiovascular diseases in animal models.
