Our project is a target shooting system consisting of a target board that provides visible feedback to the user after making
an accurate shot via LEDs, a laser rifle, and a smartphone app that can control the settings of both devices using
Bluetooth. This provides a safe and entertaining but also educational experience that can be used to train to handle and
aim firearms. Our main goals were to make the system work at a distance of at least 15m away and improve on similar
work from past UCF projects and market technology. To ensure use at 15m away, we created a Galilean beam expander to
decrease the laser divergence angle for increased range of use. We improved on other technology by increasing
customization of our device settings via mobile app and prioritizing portability. We also improved by making our system
usable in any lighting environment, be it day or night. To ensure proper use in daylight, we used IR receivers, photodiodes
that only respond to 940 nm light modulated at 38kHz, in our target board. Since we used various sized target areas, we
wanted to minimize the number of receivers in each target area to just one to reduce power consumption. We 3D printed
PETG lenses that not only expanded the incoming beam but also reduced optical and thermal noise. For use in night time,
we made a night vision scope system that uses IR. We made a 4x rifle scope that is used to calibrate for aiming and can
combine with a CMOS camera and LCD display such that the view through the scope is shown on the display. We made a
variable-focus IR flashlight for illumination at night. We also made a lens system for the CMOS camera to reduce the
FOV for a better image.
