Abstract
A sensing module includes a high speed, linear image sensor and an optical unit facing the sensor. The unit includes an optical element having a curved surface and a covering on an outward surface of the optical element. The covering has a slit formed therein. The optical unit 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 linear sensor while light impinging at a non-normal angle to the slit, at any location along the slit, is imaged on a non-central pixel of the linear sensor.
