I just wanted to share a pretty peculiar observation I noticed the other night.
I was using my DL Aurora and quickly swiped the dot across the wall and noticed something odd. My persistence of vision didn't produce a continuous line like what is usually observed when you scan a laser. Instead, I observed a trail of dots, like individual photon frames. I have attached a image to represent what I mean. I wondering if it is something others can verify, or if it is just me.
I pondered about what could be the cause of the phenomena. Something to do with the yellow cones? The DPSS process? The Aurora is actually a high repetition pulsed laser?
I ruled out scotopic shifting by testing in light and dark conditions (eyes adjusted first) I also checked the wavelength band by testing with 532 and 650.
If anyone has any ideas please feel free to comment. I personally believe it could be something to do with pulsed operation, but have no means of verifying this.
