1. General 1-1.Operation principle The UST-10LN is a scanning laser range finder. The sensor emits pulsed laser beams within a 270° field of view. When the emitted laser beams are reflected back from an object, its distance is measured by applying the Time-of-Flight (TOF) principle. The sensor has 1081 measurement steps with a 0.25° pitch. The user can preset up to 31 area patterns in the sensor. Each area has 3 outputs; Output 1, Output 2 and Output 3 (see Figure 1).
1-6.Hysteresis of detection area When objects are present on the boundary of an area, sensor may not detect them continuously. In such cases, the output signals oscillate frequently between the ON and the OFF states. Sensor has hysteresis function that temporarily increases the area size to prevent such oscillation. Ratio of increase can be specified using the application software. 2.

6. Area configuration It is possible to configure two types of area in the sensor. 1. Normal configuration 2. Independent configuration 6-1 Normal configuration In the normal configuration, the area for Output 1 is configured first and the shape of it can be configured freely. Areas for Output 2 and Output 3 are dependent on the set area of Output 1 and therefore they are configured inside it. The shapes of Output 2 and Output 3 areas can be straight, fan shape or ratio (Figure 3).
6-2. Independent configuration In the independent configuration, areas for Output 1, Output 2 and Output 3 can be configured freely. The field covered by each output can be completely separate from the other output areas or there can be an overlapping region between the output areas Figure 5 (a) and (b). ※Output 2 represents the detached region configuration Figure 6 and Table 3 show the relationship between the object position and the output states.
