Peter Sidi MEYTON, ISSF Shooter Of The Year 2009, trusts in for years.

The optical MEYTON measurement system measures the

bullet flying through the frame with the aid of infrared light

barriers. A single infrared light barrier consists of the

following components:

The MEYTON measuring frame contains 192 to 512

(depending on the size) independent light beams arranged

in a grid on the inner surfaces of the frame. The infrared

emitters of the light barriers generate a continuous light

curtain in the frame. When a bullet flies through this light

curtain, several light barriers on the horizontal x-axis and

vertical y-axis of the measuring frame are interrupted

partially or completely.

An infrared emitter emits the infrared light in a bund-

led light beam.

A receiver opposite the infrared emitter measures

intensity of the incoming infrared light beam.

What do we do better?

For more than 20 years MEYTON Elektronik GmbH has supplied indoor and

outdoor shooting ranges with state-of-the-art optical electronic measuring

equipment.

Thanks to new technologies, enhancements and our long term experience we

have brought our measurement system to perfection. Due to our unique

measurement procedure, we are one of the leading companies in electronic

bullet measurement.

Our accuracy of measurement

The infrared receivers opposite to the infrared emitters

register the interruption of the light barriers due to the

decrease of intensity of the incoming infrared light. The

measurement of the residual intensity is so accurate that

every infrared receiver distinguishes approx. 165 different

shadowing intensities.

This extremely precise measurement of the residual

intensity for every single light barrier which has been

covered by a bullet flying through the frame allows for an

accuracy of 1/100 mm. Together with the information about

the position and the amount of the partially or completely

covered light barriers the position of the bullet in the frame

is determined with an accuracy of 1/10 mm.

Another aspect contributing to the high measurement

accuracy are the fixed hole matrix panels which are

installed at the inner edges of the measuring frame. Laser

technology is used to manufacture the stainless steel

panels for two important reasons.

The precise cutting of the panels and drill holes allows for a

sharp and fixed light beam. Due to the fixed panel grid, the

positions of the single light beams as well as the frame

center are clearly defined. Contrary to other measuring

systems the MEYTON measuring The large number of the

measuring sensors and the fixed panel system ensure a

constant accuracy of measurement over the whole

measurement area of the frame. smallest distinguishable

shadowing intensity: approx. 1/100 mm wide frame

possesses a „fixed center“.

Furthermore the stainless steel is resistant to temperature

fluctuations. Variable external conditions do not influence

the position of the light beams, the „fixed center“ is always

in the same postion.

panel system ensure a constant accuracy of measurement

dirt particles

Dust remains dust

A big advantage of the MEYTON measuring method over

other optical measurement systems, e.g. camera systems,

is the surface of the sensors which is many times larger. In

the MEYTON system, the multitude of the independent

sensors in the grid generates a sensor area which extends

over the entire inner edges of the measuring frame.

Therefore in most cases only a few sensors of the

measuring frame are affected by dust or other dirt particles

(see right figure). Even if a sensor is partially covered by

dirt particles, the MEYTON system compensates by

increasing the transmission power of the infrared emitters.

A constant measurement accuracy is thereby ensured

over the entire measurement area of the frame. camera

system dirt particles sensor area In a camera system, the

incoming light beams are bundled with the aid of a lens on

a photo sensor that measures the position of the bullet.

Normally, such measuring frames only have two photo

sensors (one for the x-axis and one for the y-axis of the

measuring frame). As the photo sensors are very small in

comparison with the width of the measuring frame, even

small dirt particles cover a considerable part of the

available sensor area (see left figure). Consequently, the

sensor is „blind” over a significant part of the measurement

area (see the grey sector in the left figure).

A constant accuracy over the entire measurement area of

the frame is no longer guaranteed.

low susceptibility to dirt and variations in

temperature

After a developement time of four years, the first open

shooting range with optical hit evaluation was in- stalled in

Ibbenbueren (Germany) in the year 1988. The innovative

(groundbreaking) invention of an electronic hit display

quickly became known in the shooting clubs in the

surrounding region.

In the year 1991 the company MEYTON Elektronik GmbH

was established by the inventors Paul Meyer and Ewald

Etgeton ( = Meyer, = Etgeton). Shortly afterwards

Udo Witte, the present managing director, joined the

company. The ensuing rapid technological progress of the

company is due to him.

The German shooting sport federation (Deutscher

Schützenbund (DSB) tested the system. In 1996 the

MEYTON Shootmaster system was authorized as the

MEYTON Elektronik GmbH became known nation- wide

due to the support of the national league founded in 1996.

The club and national league spectators were convinced of

the reliable measuring method and of the interesting visual

display of the results. Since then hundreds of competitions

(shooting clubs, districts, counties and states as well as

national, European and World Championships) have been

conducted to the utmost satisfaction of the organizers.

• Shooting association Berlin-Brandenburg in Berlin

• Shooting federation Brandenburg in Frankfurt / Oder

• Shooting association Hesse in Frankfurt / Main

• Shooting sport association Lower Saxony in Hanover

• Shooting federation Northern Germany in Kiel

• Shooting federation Upper Palatinate (administrative

district of the state of Bavaria)

• Shooting association Saar in Saarbrucken

• Shooting federation Saxony in Leipzig

• Shooting federation Westphalia in Dortmund

“first fully electronic measuring system for compe-

titions and championships approved by the DSB”.

The big success over the last years at home and abroad

has lead to a continuous growth of the work force, the

production and warehouse capacity.

The application for approval of the MEYTON systems by

the international federation ISSF is the logical

consequence of the global demand. The operating test of

the measurement chamber has already been completed

successfully and the approval is imminent.
