Abstract
A range finder for determining a distance to a target object includes a thermoelectric module and a range finding unit. The range finding unit includes a light source for emitting light onto a target object, a light receiving unit configured to receive light reflected by the target object, a distance calculation unit for calculating the distance to the target object based on the reflected light, and a display unit for displaying the calculated distance to the target object. The thermoelectric module generates electricity from a thermal gradient, produced from a user's body heat that is transferred to the module. The electricity power generated by the thermoelectric module powers the components of the range finding unit. Related methods are also provided.
