Laser Light Effect Why am I seeing variations in the reflected laser light when I look at the reflection from a diffuse surface?
Here is the experiment. I reflected my tripod laser off of a CFB at my home. I noticed a strange effect and turned the light out to see it better. As I looked closely, I could see small variations in the reflected light. They looked like tiny points of light within the reflection. My first feeling is that it was an effect of the light hitting the photo receptor cells on my cornea. The problem with that was that as I move one way or another, or change the angle of view, I am moving along with the reflected dots. Has anyone seen this in a lab somewhere?
That would explain why as I got closer, I saw less "particle", and more "wave". Thanks for the answers. You college educated people are great for something, dont let anyone tell you different.
I was just reading the paper on the Holographic Universe and wondered if it was related. Turns out it is. http://en.wikipedia.org/wiki/Holographic_interferometry
I have no idea what a CFB is but I think I know the answer.
Because laser light is coherent and monochromatic when it hits any kind of diffuse object you get regions of constructive and destructive interference. These look like bright and dark spots to the eye, and create a speckle pattern.
If you point the laser at a surface whose structure is constantly changing you will see movement in the speckle pattern. Examples are a cup of tea with milk (brownian motion) and human skin (movement of blood cells). This movement in the pattern can be used to measure peripheral blood flow through the skin.

DJ Laser Light Fireworks Effect
Dj Lighting
There are other props that can be used such as dry ice, bubble machines to mention a few; however these props work best for such things for DJs at a Toronto wedding. DJ lighting however, is something that can be a simple system that many other DJs will use, or it is something that a DJ will have as part of their evening to enhance the show.
As mentioned above, a lighting system can consist of strobe lights to brighten up the dance floor, or light up the banquet hall venue for your next wedding in Toronto. Some other lighting effects can include beautiful laser light shows that are synced up to light up and move with the sound of the music. This adds a great element to your event because the ambiance of the entertainment is enhanced; making sure that all the guests or people coming to enjoy the show of the DJ is very memorable. Another advantage of effective lighting by the DJ is that is assists other services within the show to create a great scene, something that is always a good thing.
For example, if you as a DJ is playing at a club and you are having the show filmed, then having a great lighting system in place helps you film the event much more effectively then if you were lacking a good lighting backdrop. This also applied to weddings, because a wedding will have wedding photographers and wedding videographers, so it is important to stand out with all the wedding services being offered on the night of a wedding that you make your presence be known as a wedding DJ.

They will truly make your next wedding, or live-to-air club night event come alive.
They likely seem similar. We may be able tell the difference, but we don't know why upon looking at the blue lights that we can tell the difference.
If we disperse the light and look at its frequency composition, we can tell the difference, and there will be one. The blue filter around a nearly white incandescent bulb will produce a continuous spectrum. A blue laser produces monochromatic blue light. Flames typically produce light in emission bands, with some background continuous spectrum much fainter.
