Optical phantoms are used to validate optical measurement methods. The stability of their optical parameters over time allows them to be used and stored over long-term periods, while maintaining their optical parameters. The aim of the presented research was to investigate the stability of fabricated porous phantoms, which can be used as a lung phantom in optical system. Measurements were performed in multiple series with an interval of 6 months, recreating the same conditions and using the same measuring system consisting of an integrating sphere, a coherent light source with a wavelength of 635 nm and a detector. Scattering and absorption parameters were determined on the basis of the measured reflectance and transmittance. The tested samples were made of silicone and glycerol in various proportions.
光学体模用于验证光学测量方法。其光学参数随时间的稳定性使其能够长期使用和存储，同时保持其光学参数。本研究的目的是研究制造的多孔体模的稳定性，该体模可在光学系统中用作肺部体模。测量以6个月为间隔进行多个系列，重现相同条件并使用由积分球、波长为635 nm的相干光源和探测器组成的相同测量系统。散射和吸收参数是根据测量的反射率和透射率确定的。测试样品由不同比例的硅酮和甘油制成。
