ABSTRACT:
An archery practice device projects a moving hunt scene on a screen. In one embodiment of the invention, a continuous plane of IR light is located prior to the screen, an arrow carrying a reflector is detected as it penetrates this light plane, and IR illumination is reflected back toward the archer and a full-screen radiation detector. In another embodiment, a piezoelectric motion detector senses impact of an arrow on the screen, an IR source is momentarily triggered by the motion detector, and IR illumination is reflected by the arrow toward the full-screen radiation detector. The detector generates a full-screen signal indicating the point of arrow impact on the screen. Upon detecting the arrow, the moving scene is frozen on the screen. The visual content of the frozen scene is coordinated to the full-screen signal from the detector, whereupon a hit zone image is projected on the screen to indicate the arrow impact point relative to the frozen scene. The arrow does not penetrate the screen, and drops vertically downward adjacent to the bottom of the screen at a location between the front of the screen and the archer.
