Techniques for facilitating light signal assessment receiver systems and methods are provided. In one example, a light signal assessment device includes a light signal detection device including a filter array, a detector array, and a measurement device. The filter array is configured to filter a light signal incident on the filter array. The detector array is configured to receive the filtered light signal and generate a light signal detection image based on the filtered light signal. The measurement device is configured to determine a characteristic associated with the light signal based on the light signal detection image. The assessment device further includes a logic device configured to generate an output based on the characteristic. Related methods and systems are also provided.

A vision-cued random-access LIDAR system and method which determines the location and/or navigation path of a moving platform. A vision system on a moving platform identifies a region of interest. The system classifies objects within the region of interest, and directs random-access LIDAR to ping one or more of the classified objects. The platform is located in three dimensions using data from the vision system and LIDAR. The steps of classifying, directing, and locating are preferably performed continuously while the platform is moving and/or the vision system's field-of-view (FOV) is changing. Objects are preferably classified using at least one smart-vision algorithm, such as a machine-learning algorithm.

A multi-spectral lens comprises a circular polarizer and a tunable cholesteric filter having an associated reflection band. Incoming light is circularly polarized to one handedness by the circular polarizer, and the tunable cholesteric filter transmits the circularly polarized light and reflects the opposite handedness of the circularly polarized light if within the reflection band of the filter, with the reflection band of the tunable cholesteric filter varying with a control voltage. In a preferred embodiment, a mirror is arranged to receive light transmitted by the tunable cholesteric filter and reflect it back towards the filter with flipped handedness, with the reflected light with flipped handedness that is within the reflection band of the tunable cholesteric filter reflected by the tunable cholesteric filter back toward the mirror. The architecture described effectively converts the reflection band of a tunable cholesteric filter into a tunable bandpass filter for a multi-spectral imaging lens.

A non-volatile, absolute rotation sensor employs a radial guide and spiral guide rotating with respect to each other to move a marker element continuously along the radial guide so that a distance of the marker element along the radial guide provides an indication of shaft movement over multiple turns. A sensor system senses the distance of the marker element along the radial guide to provide an electric output.

A nonvolatile, absolute multi-turn rotation sensor employs a magnetic particle that is indexed around a serpentine channel with successive passes of a magnet caused by rotation of the rotation sensor shaft. Sensors at regular locations around the track allow determination of the position of the magnetic particle and thus the total number of revolutions of the shaft.
