美国波士顿眼科研究所研制的扫描激光检眼镜(SLO)与传统的检眼镜截然不同。借助这种新方法,检查者可以看到更加清晰,更为明亮的病人视网膜图象。另外,如果研究人员想知道视网膜的哪个区域将信号送入大脑,或者哪部分可能损伤,可以将图象直接投影到视网膜上进行研究。在扫描激光检眼镜中,一至二束氩(或氪,氦-氖)激光经声光偏转器后射入眼睛,声光调制器象光栅
The United States Boston Eye Institute developed scanning laser ophthalmoscope (SLO) and the traditional ophthalmoscope is completely different. With this new method, the examiner can see a clearer and brighter patient’s retinal image. In addition, if researchers want to know which area of the retina sends signals into the brain, or which part may be damaged, images can be projected directly onto the retina for research. In scanning laser ophthalmoscopes, one to two beams of argon (or krypton, helium-neon) laser light enter the eye through an acousto-optic deflector, and an acousto-optic modulator such as a grating
