Abstract
The present disclosure introduces an optical component attachable to a mobile communications device and operable to spectrally filter images taken by a camera of the mobile device. Systems introduced herein include the optical component, the mobile device, and an illumination source for directing light at a specific wavelength/intensity into a human mouth, such that images taken by the camera record human mouth tissue responses to the light for cancer screening purposes. Such cancer screening may also utilize a database of other response images from other patients, which may be transmitted to the database by the mobile device and/or other mobile devices.
