便携式光谱仪和旋光仪的通用智能手机插件：iSPEX 2
A universal smartphone add-on for portable spectroscopy and polarimetry: iSPEX 2
摘要：
光谱偏振法是一种强有力的环境遥感技术。它能够在一定程度上恢复空气和水中的颗粒形状和尺寸分布，这是传统光谱学所不能做到的。DAC是一种通过光谱调制进行分光偏振测量的仪器概念，提供快照，从而提供精确的高光谱强度以及线性偏振的程度和角度。成功的dac仪器包括grounddac和dac airborne，这两种仪器都能高精度地测量气溶胶光学厚度，很快还有SPEXone，它将在PACE上飞行。在这里，我们提出了一个低成本的消费者相机，idac 2，与通用智能手机的支持。智能手机使公民科学测量在空间和时间上比专业仪器更具可扩展性。通过模块化硬件设计和SPECTACLE数据处理实现通用智能手机支持。idac 2将通过注塑成型和3D打印制造。用于数据采集和处理的智能手机应用程序正在积极开发中。生产、校准和验证将于2020年夏季开始。科学应用将包括气溶胶光学厚度和地表水反射率的公民科学测量，以及低成本实验室和便携式光谱学。
英文摘要：
Spectropolarimetry is a powerful technique for remote sensing of the environment. It enables the retrieval of particle shape and size distributions in air and water to an extent that traditional spectroscopy cannot. SPEX is an instrument concept for spectropolarimetry through spectral modulation, providing snapshot, and hence accurate, hyperspectral intensity and degree and angle of linear polarization. Successful SPEX instruments have included groundSPEX and SPEX airborne, which both measure aerosol optical thickness with high precision, and soon SPEXone, which will fly on PACE. Here, we present a low-cost variant for consumer cameras, iSPEX 2, with universal smartphone support. Smartphones enable citizen science measurements which are significantly more scaleable, in space and time, than professional instruments. Universal smartphone support is achieved through a modular hardware design and SPECTACLE data processing. iSPEX 2 will be manufactured through injection molding and 3D printing. A smartphone app for data acquisition and processing is in active development. Production, calibration, and validation will commence in the summer of 2020. Scientific applications will include citizen science measurements of aerosol optical thickness and surface water reflectance, as well as low-cost laboratory and portable spectroscopy.
