Nor is it possible simply to crank up the power of the source beam, because infra-red light at high intensity can cause eye damage.

他说，“多数光不会你想让它到哪它就到里”。 也不可能简单地增强光束的强度，因为高强度的红外光会伤害人眼。

Using light as an external power source can alleviate the weight and mass of having an onboard system, leaving room for scientific payloads, for example, and it provides more propulsive power.

利用光束作为外部能量源可以减轻火箭自身携带的系统重量和质量，为科学研究扩大有效载荷空间，并提供更大的推力。

The light source module, the reflector module and the power module are designed with standard modules, which are convenient to replace and reduce the cost of maintenance.

光源组件、反射器组件、电源模块等均采用标准模块设计，方便更换，减少后期维护成本。

Admittedly, this unusual memory requires an internal light source, but the amount of illumination required is tiny and consumes less power than the logic circuits that are used to read data in and out.
