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: Means are suggested for calibration in the field of optical sensors, e.g. characterizing and calibrating an optical sensor chip. In order to address complexity of sensor data with high accuracy the optical sensor, e.g. an optical sensor is not provided as an already calibrated unit. Rather, sensor response data may be recorded in a defined or standardized environment, e.g. at a production line, and with high precision. This high standard sensor response data can be obtained on a per device basis and, thus, is referenced with an unambiguous chip identification number, chip ID. The sensor data is complemented with a dedicated calibration algorithm which can be tailor-made to fit the optical sensor or the optical sensor chip. In order to retrieve the sensor response data and the calibration algorithm both can be made available by means of the chip ID, for example.

Abstract: A multi spectral material detection system captures spectral data and compares select spectral bands to reflectance spectra of a plurality of materials. The system identifies distinguishing features in reflectance spectra of a plurality of materials and in a plurality of spectral channels identifying distinguishing structural aspects of each material with respect to the background environments. Upon an observed spectral reflectance being proximate to one or more known spectra characteristics, the object is associated with a material of interest.
