| 发明名称 | Distance measuring methods | ||
| 摘要 | A distance measuring method includes: emitting a pulse of measuring light towards an object; receiving a pulse measuring light from the object and generating a pulse signal corresponding to the pulse of measuring light received from the object; delaying a first portion of the generated pulse signal for a predetermined time; generating an intensity signal indicative of an intensity of the generated pulse signal, while delaying the first portion of the generated pulse signal; amplifying the delayed first portion of the generated pulse signal using a gain dependent on the generated intensity signal; and determining a value representing a distance based on the amplified delayed first portion of the generated pulse signal. | ||

| 主权项 | 1. A distance measuring method comprising: emitting a pulse of measuring light towards an object; receiving a pulse of measuring light from the object and generating a pulse signal corresponding to the pulse of measuring light received from the object; delaying a first portion of the generated pulse signal for a predetermined time; generating an intensity signal indicative of an intensity of the generated pulse signal, while delaying the first portion of the generated pulse signal; amplifying the delayed first portion of the generated pulse signal using a gain dependent on the generated intensity signal; and determining a value representing a distance based on an occurrence time of a signal feature of the amplified delayed first portion of the generated pulse signal relative to a time which depends on an emission time of the pulse of measuring light emitted towards the object. | ||
