US: Mobile app planned for detecting laser illuminations

A U.S. company will be releasing a mobile app allowing smartphones to detect, measure and record the location of laser illuminations. Pilots are the primary intended users for the app, which is currently called “Laser Event Recorder” or “LERapp”. In a planned upgrade, the app will also notify other nearby pilots of the illumination event.

LERapp was developed a few years ago by Dr. Craig Williamson of the U.K. Defence Science and Technology Laboratory (Dstl). The app uses the smartphone camera; when a laser or bright light event is detected, the app makes a digital record. This includes a picture of the event, the GPS location of the phone, the user’s heading, the date and time, and laser parameters such as the beam color and estimated irradiance. A March 2013 paper, presented by Dr. Williamson at the International Laser Safety Conference, describes the app in more detail.

As far as LaserPointerSafety.com can determine, the app was never made publicly available such as being put on an app store.

To commercialize LERapp, in December 2016 it was licensed to Profound Technologies, Inc. of Warner Robins, Georgia, who will be doing further development and marketing in major regions such as the U.S., U.K. and Europe. Profound’s president Randall Fitzgerald said that there are two planned versions.

One version will be a free or low-cost basic app that has the current features of LERapp. Profound will also be developing a central database where laser incident reports will be automatically filed, which then can be pushed out to other users of LERapp such as nearby pilots. These notifications would be available in a higher-cost version, or perhaps the notification feature would be a “freemium” add-on to the basic app.

The app will not directly be able to locate the laser’s location — the only geographic information stored is the GPS location and heading of the smartphone at the time of the incident. However, having a photo of the laser illumination may allow law enforcement to locate landmarks or street patterns. Also, Profound is considering future versions which could triangulate a ground location or area based on multiple illumination events reported to the database within a short timespan.

LERapp currently runs on Apple’s iOS operating system for iPhones. There is as yet no public release schedule for the basic or database versions. At the time of Apple App Store release, Profound also intends to have an Android-compatible version available.

World: Smartphone app can remotely control handheld laser

Internet seller Wicked Lasers has introduced a $200 handheld laser whose beam power and on/off patterns can be remotely controlled by a smartphone app. The Evo is a green (532 nm) laser with a minimum of 100 milliwatts of output power (safety Class 3B) and a beam divergence of 1.5 milliradians. The stated Nominal Ocular Hazard Distance is 154 feet or 47 meters.

The company’s free “Evo” app is available on Apple iOS and Android app stores. A smartphone connects to the Evo laser either using a cable from the audio output jack, or wirelessly using an optional $40 Bluetooth module that attaches to the laser. Once connected, the app allows remote control of the laser’s output power, and of its flashing frequency. (Although anyone can download the app, the software does not appear to run unless connected to a Wicked E4 series laser such as the Evo.)

The software code is available as open source, so that hobbyists can create their own software to custom-control the Evo.

UK: Low-cost laser event recorder is an iPhone app

A U.K. researcher has developed a laser event recorder which can run on an iPhone, iPad, smartphone, or pilot Electronic Flight Bag. The “LERapp” records laser or bright light events; each record includes a picture of the event, the GPS location, heading, date, time and laser parameters such as color and estimated irradiance.
