V! Laser sensitivity: How is it achieved?

[karl56]

Wondering if anyone has some knowledge as to how the V1 achieves the great laser detection. What is its design/construction that other RD manufacturer are not doing?

Also, does the V1 has a true rear laser lense, or merely a "light pipe" like the others?

thanks

For one, the V1 uses a compound parabolic concentrator, which the others do not. There is likely some other things involved as well.

Yes it's a real laser sensor, but the rear doesn't have a compound parabolic concentrator like the front.

I wonder why other manufactors don't try to do something similar to this to achieve better laser sensitivity?

Does V1 have a patent on it or something?

[jimbonzzz]

There's no V1 patent on it. I guess they either don't want to add additional cost to the detectors, or they don't care as much about laser performance...

The compound parabolic concentrator is pretty big too. My guess is the cost plus it doesn't give that much of an advantage preventing a ticket.

I seriously wouldn't mind it though, even if the gain having it is minimal. Just my opinion though.

This is why the Valentine One can detect laser better than the rest.

The Valentine One back in the day had six individual infrared laser photo diodes mounted on the laser board and facing the front of the car (two at an angle to obtain greater coverage).

The current Valentine One has a huge compound parabolic concentrator for laser detection that will alert almost 100% of the time when shot with laser from almost any distance.






Some testing of the Valentine One's laser detection:

These are the exact number of times that each detector alerted to laser from 1000 feet or less:


V1

179 out of 180 times


RX65

46 out of 180 times


STi

57 out of 180 times


Cobra

25 out of 180 times


X50

81 out of 180 times


Whistler

16 out of 180 times

When did V1 quit using the diodes; what year? When it used the diodes, was it still tops as far as laser detection?

Follow-up question:

How does the Escort ZR3 (and SR_ cousins) achieve their level of what is generally considered as among the best reception for active jammers (even when compared to the LPP/AL, which each use an optical collimator)?

The V1's design, to me, as a flashlight enthusiast, just "makes sense."

But what's allowing the ZR3 to do so well, compared to its counterparts?

dam that laser thing is HUGE on the v1
