Systems and methods for non-contact biometric sensing

A non-contact biometric sensing device comprising:

• a plurality of ranging lasers each configured to emanate a visible laser beam, the ranging lasers oriented such that the visible laser beams converge at a point distant from said sensing device, the laser beams operable in aiming said sensing device at a target object;
• a laser doppler vibrometer sensor configured to sense mechanical motion associated with the target object;
• an infrared camera configured to sense thermal distribution data associated with the target object;
• a visible light camera operable to obtain an image of the target object that includes the visible laser beams, said sensing device programmed to determine a distance to the target object based upon a distance between the visible beams and calculate biometric data based on at least one of the mechanical motion sensed by said laser doppler vibrometer sensor and the thermal distribution data sensed by said infrared camera, the biometric data including at least two of a pulse rate, a respiration rate, and a map of temperature distribution on the target, said sensing device further operable to use the determined distance to the target to focus said laser doppler vibrometer sensor, said infrared camera and said visible light camera on the target object, said sensing device further operable to generate, based on the biometric data, at least one of a potential diagnosis for the target object and a quantitative measure of target health represented as a score within a predefined range of scores, said sensing device operable to utilize data received from said visible light camera to remove hand motion associated with a user of said sensing device from the data received from said laser doppler vibrometer sensor and said infrared camera;
• and
• a portable housing containing said plurality of ranging lasers, said laser doppler vibrometer sensor, said infrared camera, and said visible light camera, said portable housing configured for handheld use.
