Abstract
A system includes a temperature sensor and a distance sensor. The distance sensor provides an indication of distance between the temperature sensor and an object to be measured. By determining the distance between the temperature sensor and the object, the system determines whether the object is sufficiently close to the temperature sensor to make an accurate temperature measurement, such as by determining whether the object completely fills the field of view of the sensor. In an implementation, the distance sensor includes a light source and a photodetector configured to detect light having wavelengths that correspond to those generated by the light source.
