COMPACT FOLDED SIGNAL TRANSMISSION AND IMAGE VIEWING PATHWAY DESIGN AND VISUAL DISPLAY TECHNIQUE FOR LASER RANGEFINDING INSTRUMENTS |
摘要 |
A compact folded signal transmission and image viewing pathway design and visual display technique for laser rangefinding instruments incorporates a beam splitting cube in the eyepiece optical space and advantageously provides an objective image focal length substantially twice that of the physical length of the instrument optical components. Through the use of some of the same optical elements in both the image viewing pathway as well as the laser transmission pathway, a relatively long transmission focal length is provided which saves in both physical instrument space and component cost while also allowing for the use of reasonably sized photodiodes with improved power output over that of previous designs. |

1. A laser rangefinder comprising:
a laser energy emitting device; a laser emitting aperture in said laser rangefinder; and a laser transmission pathway in said rangefinder for redirecting a laser beam from said laser emitting device through effectively 90° to said laser emitting aperture. |
