為了保護人眼在雷射光照射下的安全，過去許多不同的雷射安全規範已經被提出，例如: 美國國家標準協會 American National Standards Institute ，ANSI、國際電工委員會 (International Electrotechnical Commission，IEC)等。在IEC中規範了人體可接受的雷射輻射上限(Accessible Emission Limit, AEL)及人體准許的曝光值(Maximum permissible Exposure, MPE)。
目前已有學術文章利用此規範討論判斷等能量重複分布的脈衝訊號之雷射安全，卻無學者針對非重複分布訊號之課題作討論。
本論文提出一套新的評估方法適用於可見光波段下任何形式的雷射訊號，並將其理論應用在實際的產品上，以雷射掃描投影技術為例，計算雷射輻射上限值(AEL)及此系統之安全操作距離，並提出改善方法來所短雷射安全距離。

There are different regulations for eyes safety which had be established，for example: American National Standards Institute (ANSI)、International Electrotechnical Commission(IEC). IEC define AEL and MPE to restrict the laser signals in safe operation.
Previous research results only discussed the laser safety for CW signal and repetitive pulses with same energy. No scholar focuses on unrepeatable signals.
The thesis provides a method of laser safety to estimate any kind of laser signal in visible wavelength range.
We apply the above method to laser scanning projection system , and calculate safety distance. Beyond the safety distance, human eyes will not be damage.
We also provide methods to achieve the longer safety distance.
