7 shows a reflective sensor. A reflective sensor works the same way as a slotted switch, except that the phototransistor picks up reflected light from whatever is in front of the switch. Most reflective sensors have a focal length, the optimum distance where the object to be measured should be placed, typ- ically between .1 and .5 inches. A typical use for a reflective sensor is to detect motor motion by painting or anodizing the motor shaft black, then having a strip of reflective material on the shaft. As the shaft rotates, the sensor sees no reflection from the part of the shaft that is black, then high reflection from the reflective strip. Both types of optical sensors have some common characteristics that must be taken into account when designing a system that uses them, as detailed in the following sections. Figure 3.7 Reflective optical sensor...
