    Abstract: A scene generator can generate a second scene representative of a first scene by emitting a beam of electromagnetic radiation onto a plurality of prism-coupled electrically conductive elements that modulate a portion of the beam incident thereon with surface plasmon polaritons based on parameters of the first scene to yield a modulated beam that produces the second scene.

    Abstract: A light sensing apparatus includes: an arrangement of light sensing pixels, one or more pixels each associated with a noise floor and able to detect a triggering level of incoming light above the noise floor from a corresponding portion of a scene; readout circuitry to process and reset the triggering pixels; and an automatic gain control (AGC) to raise the noise floor of one or more pixels. Sometimes, the light sensing apparatus is part of a seeker that includes control circuitry to dynamically control the AGC to raise the noise floor of one or more pixels by an adjustable amount that varies in relation to the distance between the seeker and an intended target. Sometimes, the control circuitry dynamically controls the AGC in response to a concurrent triggering of two or more triggering pixels. or in response to a gain schedule corresponding to guiding the seeker to the intended target.

    Abstract: The light deflection device is configured to switch a first reflection position and a second reflection position in at least some region of the reflection part. The first reflection position is a position at which the light irradiated by the irradiation optical system is to be reflected toward the projection optical system so as to be effectively used as a part of a desired light distribution pattern. The second reflection position is a position at which the light irradiated by the irradiation optical system is to be reflected so as not to be effectively used. The detection unit is arranged at a position at which the light reflected at the second reflection position by the light deflection device can be detected.

    Abstract: A temperature-dependent current generator includes a first transistor connected between first and second nodes and providing a first voltage potential at the second node that decreases first order linearly when ambient temperature increases. The generator further includes an operational amplifier having first and second input terminals and an output terminal. The first input terminal is coupled to a second voltage potential that is first order independent of the ambient temperature. The second input terminal is coupled to a third node. The generator further includes a second transistor with gate, source, and drain terminals. The gate terminal is coupled to the output terminal of the operational amplifier. One of the source and drain terminals is coupled to the third node. The generator further includes a resistor coupled between the second and the third nodes. A resistance value of the resistor is first order independent of the ambient temperature.
