---------------------------------------------------------------------***--------------------------------------------------------------------position of shooting spot using the graphical user interface (GUI). system for detecting rifle shooting spot on the target board.
Abstract - This paper presents the application of electronics 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 used to locate the position 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 information about the score points. This all information automatically stored in the computer. Key Words: Laser, Photodiode, Controller, Visual Basics software, RF module.
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 |

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.
