一种供盲人使用的固体二极管雷达已经制成.这种雷达差不多和一般手电筒大,能在室温下正常工作.发出的脉冲光束持续时间为10微秒,功率为6瓦,使用长为半吋的?砷二极管睐泽.用硅可控整流器作电
A solid-diode radar for the blind has been made, which is almost as big as a flashlight and works well at room temperature. The pulsed beam emitted lasts for 10 microseconds at a power of 6 watts and uses a half-inch Arsenic diode Lai Ze. With silicon controlled rectifier for electricity
