基于相位恢复的透明样本3维重建系统
Three-dimensional reconstruction system for transparent samples based on phase retrieval
摘要
Abstract
In response to the difficulties posed by traditional microscopy imaging techniques in capturing the structure and thickness of colorless transparent samples,we have designed a miniature three-dimensional reconstruction system for such samples.This innovative system,breaking away from traditional optical structures,performs phase retrieval on transparent samples to achieve three-dimensional reconstruction.It requires only light carrying sample information,which is then bifurcated by a spectroscope and captured by a stereo camera.Constructed using 3D printing technology,the compact system measures just 110 mm×110 mm×60 mm,offering a cost-effective solution that is also compatible with traditional microscopy imaging equipment.It incorporates autofocus and field of view correction algorithms,which,by collecting one over-focused and one under-focused image,solve the transport intensity equation to enable phase retrieval and hence the three-dimensional reconstruction of transparent samples.Test results have shown that the system can achieve an imaging resolution of 2.46 μm under a 10×objective lens,and the phase recovery accuracy can also meet the basic requirements.Furthermore,the successful three-dimensional reconstruction of blood cells and scratches on microscope slides validates the system's feasibility and practicality.关键词
