The origin passive infrared detectors is easily jammed by factors such as environmental temperature and environmentallight intensity.
传统被动红外探测器容易受到环境温度，环境光线强度影响，误报率高。

The accuracy of phase - measuring profilometry (PMP) is greatly influenced by the environmentallight, especially in the outside of the room.
在野外运用相位测量剖面术(PMP)测量物体三维面型时，环境光场经常发生变化，从而严重影响测量精度。

You're going to be dealing with long-exposures and wide-open apertures, which means any environmentallight will creep into the frame and overpower the image.
