Hi to everyone at DIY Drones!I don't know much about UAVs, my specialization is the design of laser products. I recently made a laser range finder by accident that might be useful in UAVs.It started…Continue

Laser Developer replied to Laser Developer's discussion Laser altimeter - new design"Hi Thomas, thanks for your interest.
1. In many cases the LRF will measure water like dams and rivers. In some cases, if the water is very clear or very still it may lose signal.
2. I have not tested this LRF design in cold conditions but my past…"
Tomas Soedergren replied to Laser Developer's discussion Laser altimeter - new design"Hi Laser,
VERY intereting gadget, and IMHO a candidate for upgrade/ replacing the (not so easy and reliable) sonar system we use today on the ArduCopters. The cost is much higher, but some of us would be prepared to pay if it offers new level of…"
Laser Developer replied to Laser Developer's discussion Laser altimeter - new design"Glad you like the manual Vladimir.
1) Yes. The optics have been made separate from the electronics so that they can be scanned using a servo.
2) I think that it is important to make the LRF available to as many people as possible, so I will sell…"
vladimir.d.makarov replied to Laser Developer's discussion Laser altimeter - new design"Cliff,
Why would you need range of 1000m? 100m seems plenty for DIY-drone applications....?
Laser Developer,
Wow, the documentation you provided is excellent, explains how laser rangefinding works. This technology is very interesting.
Couple…"
Laser Developer replied to Laser Developer's discussion Laser altimeter - new design"Cliff, the technology for longer ranges is a bit different. Usually the resolution and short range capability are compromised and a laser with higher peak power and precision optics is used. The technology behind long range LRFs is well understood…"
Cliff Gill replied to Laser Developer's discussion Laser altimeter - new design"Would you have an option for a longer range device? Like 1000 meters or so?"
Laser Developer replied to Laser Developer's discussion Laser altimeter - new design"Hi Vladimir,
Thanks for your feedback. This is a time-of-flight laser, triangulation devices are limited to a range of a few meters.
The key to long range performance, high resolution and relatively low cost is the timer chip - DS00VQ100. This chip…"
vladimir.d.makarov replied to Laser Developer's discussion Laser altimeter - new design"Laser Developer,
This looks really cool and at $450 it is reaching a point where it can be used for hoppy/amateur applications.
Is this laser rangefinder based on the triangulation or time of flight techniques?

Laser Developer replied to Kris's discussion Does anyone know of a LIDAR Unit that can fit on an Aerial UAV?"What kind of performance do you need - range, update rate and resolution?"

Laser Developer replied to Dennis's discussion Laser Altimeter"http://www.diydrones.com/forum/topics/laser-altimeter-new-design?
Sorry, I'm new to this forum and am not sure how to link to other discussions."
Laser Developer replied to Laser Developer's discussion Laser altimeter - new design"The main differences are:
The accuracy is better (LRF = 1cm; opti-logic = 1m)
The resolution is better (LRF = 1cm; opti-logic = 20cm)
Minimum range is better (LRF = 0m; opti-logic = 4m)
Calibrated update rate is better (LRF = 100Hz; opti-logic =…"

Eraser replied to Laser Developer's discussion Laser altimeter - new design"I have a couple of the 800 yard version, They are very nice, but don't offer centimeter resolution, Mine inc/dec at 1 foot intervals.. Work great out at 800 yards, down to around 18 inches or so.."
