Physio-Anthoropological study on non-visual effects of blue-pulsed light

这项研究的目的是阐明蓝脉冲光的非视觉效应。我们观察到，即使在极短脉冲宽度（0.5-2 us）的蓝脉冲光照射下，瞳孔收缩（瞳孔缩小）也会发生非视觉效应。当辐照强度与脉冲宽度的乘积相等时，高辐照度和短脉冲宽度的条件会产生明显的微缩现象。蓝光照射时脑电信号的衰减比蓝绿光同时照射时更强，蓝光照射时脑电信号的α衰减系数也大于蓝绿光同时照射时的α衰减系数。我们证实了脉冲光的亚加性响应。在光子密度相同的情况下，蓝脉冲光对视网膜电图的光负响应（PhNR）大于其他颜色光对视网膜电图的光负响应。

The purpose of this study was to clarify the non-visual effects of blue-pulsed light. We observed that the nonvisual effect pupillary constriction (miosis) occurred even during blue-pulsed light irradiation of very short pulse widths (0.5-2 us). When the product of irradiance intensity and the pulse width were equal, the condition of high irradiance and short pulse width was shown to produce marked miosis. The miosis during blue light exposure was stronger than that during simultaneous exposure to blue and green light, and the alpha attenuation coefficient of the EEG for blue light exposure was also greater than that during simultaneous exposure to blue and green light, despite the double irradiance intensity of the combination. We confirmed the subadditive response to pulsed light. Even when the photon density was same, the electroretinogram photopic negative response (PhNR) during the blue-pulsed light exposure was greater than those during the exposure to lights of other colors.
