An imaging apparatus with a 3D thermal imager, a signal processor, a laser, an optical scanner, a controller, and a bimodal array which operates a plurality of slow response thermal detectors for generating a 2D thermal image as input to the signal processor. The controller operates the bimodal array, the laser, the optical scanner, and the thermal imager in predetermined sequence to derive range data for communication to the signal processor which interlaces the 2D thermal image with the range data to generate 3D thermal imaging. A method using a slow response thermal detector for deriving a detected analog signal from an emitted laser pulse returned from a target, asynchronously sampling the detected signal for deriving therefrom two series of time events corresponding to the ascending and the decaying portions of the detected signal. The time of flight and range being calculated by using the two series of time events.

Techniques for modifying operation of sensors using collected sensor data are provided herein. Sensor data describing a physical environment of a user authorized to access an access-controlled resource is collected according to an initial mode of operation. The initial mode of operation defines an initial performance for at least one sensor used to collect the sensor data. In response to detecting presence of a different user in the physical environment of the authorized user based on the sensor data, the at least one sensor is switched from the initial mode of operation to a modified mode of operation. The modified mode of operation is different than the initial mode of operation and defines a revised performance for the at least one sensor used to collect the sensor data.

In an authentication device, an image conversion unit converts a visible light image obtained by capturing a region including an iris of a subject in visible light, and generates a converted image. For example, the image conversion unit converts the visible light image into a monochrome image. A feature value extraction unit extracts a feature value of the converted image. A collation unit performs authentication of the subject by collating the feature value extracted from the converted image with a feature value generated from an infrared image of an iris.
