Detection System Protects FOBs from Cameras, Rifle Scopes

ScannerTAMPA — A San Diego-based small business called Torrey Pines Logic displayed a small, mobile optical detection system at the Special Operations Forces Industry Conference here. It emits a laser pulse to detect nearby surveillance gear such as cameras, rifle scopes or various observation lenses.

The Beam 100 Optical Detection System is engineered to detect optical targets out to just beyond a kilometer, providing a protective envelope for forces on a Forward Operating Base or small units on the move in a fast-moving tactical situation, said Russell Purcell, Lead Engineer, Torrey Pines Logic.

In essence, the technology is designed to let forces know if they are being “surveilled’ or watched by a nearby adversary or potential adversary, Purcell explained.

“So the laser pulse comes in and reflects off of each piece of glass inside a lens. Return pulses create a signature. The receiver captures and analyzes that signature. You don’t get glass, bottles and non-optical devices. If you get a detection is going to be an object of interest to you,” he said.

The Beam 100, which continuously scans a 360-degree field of view, is connected to a computer which uses algorithms, software and digital mapping technology to geo-locate the origin of the signature of the optical device in the area of interest, Purcell added.

  1. One thing not being explicitly mentioned in that promo is that the beam could probably be easily tuned to be an offensive tool via blinding the people on the other side of the scopes.

    Wait wait – this computer uses software AND algorithms? Consider me impressed.

  3. "So the laser pulse comes in and reflects off of each piece of glass inside a lens. Return pulses create a signature. The receiver captures and analyzes that signature. You don’t get glass, bottles and non-optical devices."

    I suppose the device is tested in laser returns of high quality optics-grade glass vs beer bottles and such. The only concern is that as an active device it's limited by scan rate over a given area, and resolution of the scanned area. I assume it uses a very fine stepping motor to step very small increments, since if one is too far away, a single rotational movement might "skip" over a target. Similarly, the laser's power must also be powerful enough to assess everything that is covered in a single rotational step.

    Considering the farthest sniper rifle shot is something like 2+ km, that's as far as you need to go to stop people from sniping you. But when it comes to surveillance with optics…

  4. I proposed this for helo use against sub periscopes when I was a NAVAIR civillian but no one was interested. Diode pumped lasers could be scaled in intensity from dazzle to fry.

  5. For crying out loud why can't these things be kept secret? Create some black ops convention with NDAs at the door. This tactical advantage is one that should not be touted to foes on the battlefield b/c now these guys know to start developing countermeasures……………

  6. That's not great range. There are some big bore sniper rifles accurate to well over 1000 meters.

  7. Also finds every window pane and coke bottle within, 1000m so that troops can supplement their income by collecting them.

    I remember a time when soldiers just shot up the enemy, not, you know, shoot up the equipment. Seems like a waste, if you ask me. Why develop a laser to destroy specific parts? Destroy the whole darn thing.

  9. "… providing a protective envelope for forces on a Forward Operating Base or small units on the move in a fast-moving tactical situation,…"

    Woe is he who assigned to carry it.
    interesting bench project but not field ready.

  10. How fast is the Secret Service gonna mount one of these in a truck in EVERY Presidential motordade and around the White House?….

  11. This is nothing new, there have been systems like this on the market for a while now:

    CILAS SLD
    Mirage 1200
    CS300K

    etc.

    This is old news already.

  12. For giggles (and maybe a check from Torrey Pines), here's the link to the product:
    http://www.tplogic.com/products/beam100.php

    Specifications mention 360 again, the camera looks like it's on a rotating mount, so it's probable that 360 requires continuous scan. Amusingly, there's a panoramic mode, but on the Beam 110 and more expensive models.

    The brochure seems to imply a ~30 degree scan angle (http://www.tplogic.com/pdfs/beam100.pdf), see figure in upper left, subset in bottom right showing an angle of <45 degrees.

    The lesser members of the Beam family (50 and 60) disclose a 2 degree FoV in horizontal/vertical, and a 45 degree/s max scan-rate. These would scan full 360 in eight seconds.

    The Beam 100 is "Continuous scanning 360° in azimuth", and theoretically that means it scans everything in real time. -30 below and 90 above. But looking at the pictures, I don't see enough camera for it to scan /everything/ simultaneously.

  13. honeycomb lens cap…. $10
    million+ dollar optical detection device defeated.

  14. Awesome technology but I wonder how long it'll be before the Chinese steal this.

  15. Make sure the device takes a picture of the bad guy so the FBI can issue a warrent and the SEALs can arrest them and use the evidence at their trial. We wouldn't want some terrorist to have his rights violated. OR, and I am just spit balling here. Maybe we could just shoot them or drop a missle on their head like wars are supposted to be waged.

  16. Actually, these "anti optics" technologies were developed and relizedid in Russia.
    TPL is just copied them (old models/solutions).
