Abstract -This paper presentstheapplicationofelectronics
system for detecting rifle shooting spot on the target board.
This system is applicable for 10 meter range. It detects the
position of the shooting aim with the help of laser and
photodiode which are placed at the sides of board. Lasers are
placed at two perpendicular sides of board and photo diodes
or detectors are placed at the two remaining sides opposite to
the lasers. Together laser and photo diode forms a matrix to
detect position of shoot on target. Laser and photo diode
continuously monitors the target board. When shooter shoots
on target board, an interrupt occurs. This interrupted output
is given to the controller circuitry through comparator which
compares the diode output voltage with constant reference
voltage. Information at the controller port is given to LCD
which gives x-y coordinators of board using matrix of sensors.
This information is also given to the shooter through RF
module. At the receiver, computer is usedtolocatetheposition
of spot on to the circular target board using visual basic (VB)
programming. According to position of spot detected by VB
software, shooter also gets informationaboutthescorepoints.
This all information automatically stored in the computer.
Key Words: Laser, Photodiode, Controller, VisualBasics
software, RF module.
1. INTRODUCTION
Recently, many systems are used for the shooting
training and practices such as image processing,
evaluation technique, database, management
technique, etc. But these systems are very costly. In
order to solve the problem that the present shooting
training systems are costly, that cannot be affordable
by the all shooting academies for their practice. So our
project system design is quite helpful for their
academic curriculums. The system accomplishes
automatic target detection. This system diagnoses the
position of the aim with help of the sensors and
detectors which gives the data to the controller panel
through comparator which is at the back side of the
target. Controller will gives the data output to the RF
transmitter which sends data to the RF receiver. RF
receiver is connected to the computer at shooter side.
Computer uses the VB software for locating the
position of shooting spot using the graphical user
interface (GUI).

1.1 Components:
a. LASER: A laser is a device that emits light through a
process of optical amplification based on the
stimulated emission of electromagnetic radiation.
The term "laser" originated as an acronym for "light
amplification by stimulated emission of radiation". A
laser differs from other sources of light in that it
emits light coherently. Spatial coherence allows a
laser to be focused to a tight spot, enabling
applications such as laser cutting and lithography.
Spatial coherence also allows a laser beam to stay
narrow over great distances (collimation), enabling
applications such as laser pointers. Lasers can also
have high temporal coherence, which allows them to
emit light with a very narrow spectrum, i.e., they can
emit a single color of light. Temporal coherence can
be used to produce pulses of light as short as a
femtosecond.

b. PHOTODIODE: A photodiode is a semiconductor
device that converts light into current. The current is
generated when photons are absorbed in the
photodiode.Asmallamountofcurrentisalsoproduced
when no light is present. Photodiodes may contain
optical filters, built-in lenses, and may have large or
small surface areas. Photodiodes usuallyhaveaslower
response time as their surface area increases.
Photodiodes are similar to regular semiconductor
diodes except that they may be either exposed (to
detect vacuum UV or X-rays) or packaged with a
window or optical fiber connection to allow light to
reach the sensitive part of the device. Many diodes
designed for use specifically as a photodiode use a PIN
junction rather than a p–n junction, to increase the
speed of response. A photodiodeisdesignedtooperate
in reverse bias.
c. RF MODULE: RF Module is a transceivers module
which provides easy to use RF communication at 2.4
GHZ. It can be used to transmit and receive data at
9600 baud rates from any standardCMOS/TTLsource.
It works in half duplex mode.
1.2 Transmitter
Fig -1: Transmitter section.
Figure 1 illustrates the transmitter section of our
system. There are five components: 1) Laser; 2) Rifle
gun; 3) Photodiode; 4) RF module; 5) Target box. Rifle
gun is used for shooting the target. Target screen is
made from a paper with circular pattern. Laser and
photodiode arecontinuouslymonitorsthetargetsheet.
Photodiode is reverse biased by giving supply to its
negative terminal. Its positive terminal gives output to
the comparator. Another input to comparator is
constant reference voltage. When there is no interrupt
on target board the comparator gives constant output
to controller ports. When shooter shoots the target
board an interrupt occurs, which changes comparator
output. This causes change in voltage atparticularport
pin of controllerwhichdisplaythecorresponding(X,Y)
coordinators on LCD. This information is then sent to
the receiver using RF module for further processing.
1.3 Receiver
Fig -2: Receiver section.
Figure 2 illustrates the receiver section of our
system. It consists of RF receiver and computer (VB
software). RF module receives data from transmitter.
This data is analyzed by the VB software. In computer
graphical user interface (GUI) window is created on
visual basic software. GUI consists of shooter
information. This information stored manually by
player itself. It also consists of image of target sheet.
When gun is triggered by the shooterthespotontarget
board is localized onto the GUI target image.

2. SIMULATION
Fig 3 shows the simulation diagram of controller. The
port zero and port two of controller are connected to
the detectors and port one is for LCD connection.LCD
shows the information about the shooting status. As
shown in simulation, when there is a trigger on
detector 2, controller displays the hitting to detector
2 on LCD as well as on virtual terminal.

3. CONCLUSIONS
This paper proposes a rifle shooting target detection
shooting using electronic components for detecting
shooting spot on target board. The user interface
application is developed on a computer to interaction
with the VB software using RF module. Hence this
system is applicable for shooting academies for 10m
range. In future, the application range will be extended
for analyzing the performance of shooting practices
using zigbee or another module.
