Low-power laser therapy has been used for the non-surgical treatment of mild to moderate carpal tunnel syndrome,although its efficacy has been a long-standing controversy.The laser parameters in low-power laser therapy are closely related to the laser effect on human tissue.To evaluate the efficacy of low-power laser therapy,laser parameters should be accurately measured and controlled,which has been ignored in previous clinical trials.Here,we report the measurement of the effective optical power of low-power laser therapy for carpal tunnel syndrome.By monitoring the backside reflection and scattering laser power from human skin at the wrist,the effective laser power can be inferred.Using clinical measurements from 30 cases,we found that the effective laser power differed significantly among cases,with the measured laser reflection coefficient ranging from 1.8% to 54%.The reflection coefficient for 36.7% of these 30 cases was in the range of 10–20%,but for 16.7% of cases,it was higher than 40%.Consequently,monitoring the effective optical power during laser irradiation is necessary for the laser therapy of carpal tunnel syndrome. 展开更多

We employ the in-site automated observation radiometric calibration(AORC) approach to perform vicarious calibration, which does not require the manual efforts of a field team to measure the surface conditions. By using an automated test-site radiometer(ATR), the surface radiance at any moment in time can be obtained. This Letter describes the AORC approach and makes use of data to compute top-of-atmosphere radiance and compare it to measurements from the Moderate Resolution Imaging Spectroradiometer. The result shows that the relative deviation is less than 5% and the uncertainty is less than 6.2%, which indicates that the in-site AORC maintains an accuracy level on par with traditional calibration. 展开更多
