ABSTRACT:
An archery practice device simulates dynamic targets, such as in an animal hunt, on a visible screen. A video disk contains a plurality of hunting scenes which are projected via a video projector on a vertical screen whose size simulates an area normally viewed by an archer during a hunt. The screen images are comprised of pixel areas arranged in horizontal rows and vertical columns. A source of light of a spectrum outside the humanly visible range is provided adjacent the screen. Arrows penetrating this light field reflect light to a detector sensitive to light of said spectrum, but not sensitive to visible light otherwise. The detector generates a full screen signal of a plurality of pixel areas, certain of which contain indicia of light reflection from the arrow. Upon detecting such reflection, the scene frame is frozen on the screen. The frozen frame is coordinated to the signal from the light detector, whereupon a hit zone image is projected to indicate an arrow impact point relative to the frame image to show the scoring of the point of arrow impact.
