日落后“太阳树”会回复到最初的位置，发出全光谱光线，为下面的街道和行人提供照明。

When the sun goes down the solar trees will return to their original position to give off a full spectrum of light to the street and pedestrians below.

另外，内置传感器可在可视光谱与似乎红外光谱下探测到光线，计算机通过分析传感器的数据后便能够决定每个物件的颜色、类型、形状与位置。

By analysing data from a sensor that detects light in both the visible and the near-infra-red spectrum, a computer is able to determine the colour, type, shape and position of each item.

使用这个高光谱数据，科学家已经为冰面硫磺沉积物的位置绘制了地图(红色轮廓)。

Using this hyperspectral data, scientists have mapped the location of sulfur deposits on the ice surface (red outline).
