用不同波长的LED辐射源照射离体组织标本, 然后通过光谱仪接收其透过光线。比较了LED光 透射组织后的波形和波长分布, 分析了不同频率的光透过同一组织标本后的频谱, 最终得出了LED光透射组织时的最佳 波长范围。该结果可以对LED辐射源在理疗产品中的应用起到一定的指导作用。

The isolated tissue samples are illuminated by using the LED radiation sources at different wavelengths. Then, the ray transmitted through the tissue samples is received by using a spectrometer. The waveform and wavelength distribution of the ray transmitted through the tissue samples from the LEDs are compared. The frequency spectra of the ray transmitted through the same tissues at different frequencies is analyzed. Finally, the optimal wavelength range for the LEDs to transmit the tissues is obtained. This result is instructive to the application of the LED radiation sources to therapy products.
