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.
