4 3. DESIGN AND APPEARANCE 3.1 Optical design Optical design of the binoculars is presented on Fig. 1. 1 – objective lens 2 – erective prisms 3 – reticle lens 4 – eyepiece The light from the object or target you are looking at enters the binoculars through the objective lens system (1, Fig. 1

5 Fig. 1). Due to the objective lens, the image at this point is turned upside down. However, as the image passes through the prism system, (known as the erective prisms) (2, Fig. 1) it becomes right side up (erect) and changed from right to left, to left to right.

9 6.3 Measuring horizontal angle using the reticle An M22 reticle built into these binoculars enables measuring height, distance and size of a target, as well as angle between two close targets. Though reticle appearance may differ from one model to another as described in 3.2, the description below...

10 When the angle between two targets is larger than the angle measuring range (100 mils), it can be measured in several steps. The horizontal angle of cruiser shown in Fig. 5, is 130 mils (60+70=130). 6.4 Measuring vertical angle using the reticle Vertical angle measurement is similar to horizontal...

12 6.5 Using the reticle to calculate distance To determine the distance to the target use the formula: D = H/K, where D – distance to target in km, H – estimated height of the target in m, K – vertical angle of the target in mil. First, estimate the height (or width) of the target, then measure tar...

14 6.7 Calculating target's size using angle readings To calculate height and width user will need to estimate the distance to the target and measure its horizontal and vertical angles. Then using the formula for distance measurement one can calculate target’s height: H=DxK, where K is vertical angl...
