What I really want is an iOS app that helps me locate insects in a room. Start video feed, analyze pixels for a small object flying around and draw a green box around each while flying and a red box once it lands somewhere. I can take care of the rest.
My dogs do this for me, minus the green box bit. They hear bugs, locate them, and focus on them until I do the rest, then they try to eat the remains.

I think that by "secondary reflection" you are perhaps refering to a direct single reflection, rather than a double bank? But in any case it is very very unlikely that there will anything availible outside of a high caliber optics lab that can reflect cohearant laser beams in such a way as to retain a dangerous power level. The 40 watt laser is needed in order to provide a kill shot in in a small target in millisecon…
I may haven't fully understood your answer, but a typical household mirror could reflect 90% of the laser power in a single coherent direction. Any sufficiently polished metal tool would have dangerous specular direction. I'm not sure of the math for a diffuse reflection, but the laser classification is here for a reason. A human eye being transparent up to the fragile retina, yes, a laser would penetrate the eye and…
1. this is NOT a product is an Indiegogo fund raising:
https://www.indiegogo.com/projects/worlds-first-portable-mos...
the product estimated shipment should be * october 2025*
2. In the Indiegogo page, they assert it will use a Lidar ( laser based) and not a mm radar ( based on radio signals );
3. Can a Lidar track something big as a mosquito ? apparently NO:

the small Lidar for commercial use like the Sony AS-DT1 , advertised like the "World’s Smallest and Lightest Precision LiDAR Sensor" available today hare a resolution of * ±5 centimeters* that is good for an Xenomorph but not for a mosquito and, anyway , for Xenomorph there are better options :-) , see : https://www.youtube.com/watch?v=IS2PtmM9mwU
4. The video of the company on youtube seems just another computer graphic gimmick to sell vaporware, IMHO. There is a prototype someone can independently test ?
They write "Relying on the advancement of lidar detection technology, this sci-fi and magical product will soon truly become a reality", I have to say no, not for now.
Please tell me if I'm wrong.

wont your eyes be infinitely better than a phone camera for this?

any light reflected in a domestic situation will no longer be a cohearant laser.if it was very focused UV it could cause temporary blindness, but a milisecond pulse will not contain enough energy to burn @ 40 watts, all that said, it is a given that certifying lasers for full on autonomous bug zapping(a dream of billions), is a very steep regulatory hill to climb, and will not be decided on redit, or here but as inse…
A retina being easier to burn than a mosquito is the fundamental reason why we haven’t seen that tech deployed. LiDAR detection with a 2D goniometer + high power laser has been available commercially for a while. There just never was someone to create something so deceptive as to sell a 40watts device as possibly safe.

As incorrect as it is misspelled. Reflections are inherently coherent.
> if it was very focused UV it could cause temporary blindness
The wavelength being UV (which it certainly is not) is irrelevant. Blindness can result from any visible spectrum laser, or from thermal IR damage.
You've lost all credibility to me at this point.

40W is scary strong for a laser. Almost like a nuke compared to a firecracker[0]: > 5 milliwatts is wimpy. We can do better. A 1-watt laser is an extremely dangerous thing. It’s not just powerful enough to blind you—it’s capable of burning skin and setting things on fire. Obviously, they’re not legal for consumer purchase in the US. Just kidding! You can pick one up for $300[1]. [0]: https://what-if.xkcd.com/13/ [1]:…
I imagine it's not a continuous output laser, hunting mosquitoes with one would be insane.

Light being coherent and light being dangerous are two completely orthogonal concepts. A laser is dangerous because of the very tight beam, but any household mirror keeps that beam focused. Plus, a mosquito needs 100millijoules to fry (from the intellectual ventures study) which is a lot more than what a retina can handle. The short duration actually makes it even worse, because the eye lids can’t close soon enough t…
