Systems and methods for non-contact biometric sensing
First Claim
1. A method for sensing biometric parameters associated with an object without contacting the object, said method comprisingdirecting a plurality of visible laser beams, emanating from a sensing device, onto the object to provide an aiming function;
- causing a signal from a laser doppler vibrometer sensor, the signal emanating from the sensing device, to impinge the object in the vicinity of the visible laser beams;
receiving infrared data from the object at an infrared camera associated with the sensing device, the infrared data in the vicinity of the visible laser beams; and
utilizing mechanical motion data associated with the object as sensed by the laser doppler vibrometer sensor and thermal distribution data as sensed by the infrared camera to calculate biometric data associated with the object, the biometric data including at least two of a pulse rate, a respiration rate, and a map of temperature distribution on the object.

Abstract
A non-contact biometric sensing device is described. The device includes a processing device, a user interface communicatively coupled to the processing device, a display communicatively coupled to the processing device, a laser doppler vibrometer sensor communicatively coupled to the processing device, and an infrared camera communicatively coupled to the processing device. The processing device is programmed to utilize mechanical motion data received from the laser doppler vibrometer sensor and thermal distributions data from the infrared camera to calculate biometric data, when signals originating from the laser doppler vibrometer sensor and the infrared camera are reflected back towards the device from a target.
