Abstract
Devices and methods for applying heat to a platen of a biometric image capturing device are described that remove and prevent the formation of excess moisture on the platen. These devices and methods prevent undesirable interruptions of total internal reflection of a prism that result in biometric images having a halo effect. In embodiments of the invention, heater assemblies, such as electrically conductive transparent material or resistive heating elements, can be used to heat an area where a biometric object is placed to remove and prevent the formation of excess moisture on the platen. Cooling assemblies, such as electrically conductive transparent material or Peltier elements, can be used to decrease temperature of an area where a biometric object is placed to prevent overheating of the platen.
