Abstract: A positioning unit mountable on a moving object includes at least one light source measuring unit and a processor. The light source measuring units have high directional sensitivity along a first axis and low directional sensitivity along a second axis orthogonal to the first axis to capture relative angular information of the moving object with respect to a plurality of simultaneously active stationary light sources located at multiple locations in a space. The processor determines positioning information of the moving object at least from the output of the at least one light source measuring unit. Each light source measuring unit includes an optical arrangement and a linearly configured imaging sensor to receive light from the stationary light sources through the optical arrangement.

Abstract: A sensing module includes a linear image sensor and an optical unit. The unit includes an optical element having a curved, outward surface and a covering on the outward surface. The covering has a slit formed therein. The optical unit faces the sensor with the slit perpendicular to a longitudinal axis of the sensor and images a wide field of view onto a single pixel of the linear sensor, wherein light impinging normal to the slit, at any location along the slit, is imaged on a central pixel of the sensor while light impinging one of a plurality of non-normal angles to the slit is imaged on an associated one of a plurality of non-central pixels of the sensor.
