カオスレーザレーダの有効性に関する研究

Abstract

A laser is widely applied for measurements, since it is invented. There are two types of laser distance meter for short and long distance. For long distance, a laser radar using propagation time of laser light is used. Generally, a distance is measured from delay time using either a periodic signal or a single pulse. But the signal becomes to be buried in noise with increasing distance. A new type of chaos laser radar which processes by only an addition is proposed. This radar can quickly process and is comparatively strong for noise, even if low output power laser is used. To confirm the effectiveness of this principal, a prototype of chaos laser radar is produced. It is found that this laser radar using semiconductor laser is comparatively strong for noise and that the chaos laser radar is effective.
