红外数字全息是一种新兴的三维波前相衬成像技术.构建了短波红外同轴数字全息成像光路,采用角谱法重建了模拟及实验样品的复振幅分布;通过基于最小二乘法的相位解包裹算法和误差评价判据,量化了环境噪声对全息图像的影响.以仿真和实验结果验证了该技术作为一种高效易用的红外成像教学工具的可行性,并构建了实验流程体系.与传统可见光全息实验相比,其优势在于有效抑制了全息干板易被环境光污染等缺点.
Research on Integrated Teaching Experiment Design of Infrared Digital Holography
Infrared digital holography is an emerging technique for three-dimensional wavefront-contrast imaging,and holds promising potential.In this research,a short-wave infrared in-line digital holographic imaging system is developed.The angular spectrum method is employed to reconstruct the complex amplitude distribution of both simulated and experimental samples.The impact of environmental noise on holographic images is rigorously quantified using a phase unwrapping algorithm based on the principles of least squares and error evaluation criteria.Moreover,it effectively demonstrates the feasibility of this technique as an efficient and user-friendly tool for infrared imaging teaching through extensive simulation and experimental studies,accompanies by the establishment of a comprehensive experimental process system.Notably,compared to conventional visible light holography experiments,the hardware stability advantage of this approach effectively mitigates the susceptibility of holographic plates to contamination from ambient light.
