Abstract: In order to avoid friendly fire incidents in the combat theater, novel covert identification systems and methods of identifying friendly forces are provided. The systems include at least a spectroscopic imaging device and a marker that interact with each other by using a synchronized, predetermined filter tuning sequence. The filter tuning sequence enables interacted photons to wavelength hop according to the predetermined tuning sequence. As a result, the covert identification system allows friendly forces to clearly identify each while avoiding detection by enemy forces that employ conventional broadband and night vision sensors.

Abstract: Systems for and methods for in situ optimization of tunable light emitting diode sources are disclosed herein. During operation, the systems and methods obtain real-time feedback from an image sensor, and that feedback is used to tune the tunable LEDs. By tuning the tunable LEDs, the best values for the LED spectral output can be selected based on the feedback from the image sensor, and an image with improved contrast is obtained. Alternatively, the amount of time to obtain an image with acceptable contrast is reduced.

Abstract: The conformal spectral library training method (CSLTM) of the disclosure allows sets of voltages for an optical filter to be calculated by way of a direct calculation without processing large amounts of spectral information, which significantly increases the speed of processing spectral information.

Abstract: Techniques, devices and methods for discriminating a target from a background material without optimizing directly on the target are provided. The devices and methods can generate pass bands of single or multiple wavelengths of variable shape and intensity, and can also select and control the shape of the pass band profiles to improve the detection of targets of interest.

Abstract: A method for multi-target detection and an apparatus for multi-target detection are capable of detecting at least two targets in real time or near real time. The real-time detection or near real time detection can be achieved by at least one of a Recipe Group Approach, an End Member Grouping Approach, and a Pixelated Grouping Based Approach.

Abstract: Systems for and methods for detecting samples and other compounds of interest are disclosed herein. The system can include an illumination source that is configured to emit light in a variety of different wavelength bands, an optical filter, a camera chip, and an optical path configured to direct the light emitted by the first illumination source at a target and direct the light reflected from the target to the at least one camera chip. The illumination source and the optical filter are transitionable between a first tuning state corresponding to a target tissue and a second tuning state corresponding to a background tissue. The system can be configured to record images at the different tuning states and generate a score image corresponding to the target tissue based on the recorded images.
