Calibration of spatially modulated snapshot imaging polarimeter based on phase-shift interferometry.

The snapshot imaging polarimeters (SIPs) using spatial modulation have gained increasing popularity due to their capability of obtaining all four Stokes parameters in a single measurement. However, the existing reference beam calibration techniques cannot extract the modulation phase factors of the spatially modulated system. In this paper, a calibration technique based on a phase-shift interference (PSI) theory is proposed to address this issue.

Demodulation of polarization information for a spatially modulated snapshot imaging polarimeter based on the coherent demodulation theory.

The snapshot imaging polarimeter (SIP) using spatial modulation can obtain all the Stokes parameters of the target through a single measurement. During demodulating of the polarization information of the target, the reference light calibration method is generally used, including a bandpass filter. In this work, a method to demodulate the target polarization information is proposed, which is based on the coherence demodulation theory.

Medical empirical research on forest bathing (Shinrin-yoku): a systematic review.

Aims: This study focused on the newest evidence of the relationship between forest environmental exposure and human health and assessed the health efficacy of forest bathing on the human body as well as the methodological quality of a single study, aiming to provide scientific guidance for interdisciplinary integration of forestry and medicine.

Method: Through PubMed, Embase, and Cochrane Library, 210 papers from January 1, 2015, to April 1, 2019, were retrieved, and the final 28 papers meeting the inclusion criteria were included in the study.

Result: The methodological quality of papers included in the study was assessed quantitatively with the Downs and Black checklist.
