Anyone here have access to, or own a Laser Range Finder which uses IR?

[Alaskan]

If anyone here has access to a golfing LRF or Laser Range Finder which uses IR pulses could you please have someone step out 50-100 feet and take a short video or photographs of the pulses and post? I am very interested in this but can't buy one here in Iraq to check it out myself. I am interested in the pulsed IR technology for another project. Ideally, if someone had a camera with the IR filter removed who could do this for me, it would be exactly what I'm needing.

Unfortunately not

There's a pdf here for building a short range one using an ir led, I don't know how similar it would be but it might provide some insight.

Homemade Infrared Rangefinder (Similar to Sharp GP2D120

This little toy actually triangulates, amazing.

This is interesting, more pdf to download.

Here's some numbers someone was working with.

Theses a lot of cool tech behind these, but I don't think our camera refresh rate or frames per second is anywhere near what you would need to count the pulse rate or unique identifying pulse code but I could be wrong.

Lidar is some interesting reading too.

My samsgung memory camcorder can see 980nm with no issues.

set it to darkness for best results. One time it even picked up ir from a halogen i was running at low enough volts to not even see.

incan blacks spam it with ir.

What about CMOS cameras? I have one i use to collimate IR lasers, but haven't tried anything in the 1064nm range. Even if they will work better in this wider wavelength, there is still the problem with frame repetition rate. Also, the CCDs used in spectrometers seems to work with these higher IR wavelengths.

I have found sensitivity curves for common CCD cameras and above 1000nm, they drop off fast to only a small percentage of what they can detect at 400-800nm edit: and that is with the IR filer removed.

mine sees 980 in a bright room and it sees 405 much brighter and more like 445nm

it has a f/2.8 with no zoom and it zooms ten times.


it can even autofocus on my 980 or my 808 which has no lens but is atleast 1.5w.
