A vehicular collision avoidance system comprising a system controller, pulsed laser transmitter, a number of independent ladar sensor units, a cabling infrastructure, internal memory, a scene processor, and a data communications port is presented herein. The described invention is capable of developing a 3-D scene, and object data for targets within the scene, from multiple ladar sensor units coupled to centralized LADAR-based Collision Avoidance System (CAS). Key LADAR elements are embedded within standard headlamp and taillight assemblies. Articulating LADAR sensors cover terrain coming into view around a curve, at the crest of a hill, or at the bottom of a dip. A central laser transmitter may be split into multiple optical outputs and guided through fibers to illuminate portions of the 360° field of view surrounding the vehicle. These fibers may also serve as amplifiers to increase the optical intensity provided by a single master laser.

A sensor system comprises a LiDAR unit having an emitter for laser light having a wavelength of 900 nm to 1600 nm and a receiver for light over a wavelength range which is between 800 nm and 1600 nm and at least partly below the operating wavelength of the LiDAR sensor and a cover having a substrate layer made of thermoplastic material which is arranged such that IR light emitted by the LiDAR unit and received by the LiDAR unit passes through the cover.

There is provided a time of flight sensor including a light source, a first pixel, a second pixel and a processor. The first pixel generates a first output signal without receiving reflected light from an external object illuminated by the light source. The second pixel generates a second output signal by receiving the reflected light from the external object illuminated by the light source. The processor calculates deviation compensation and deviation correction associated with temperature variation according to the first output signal to accordingly calibrate a distance calculated according to the second output signal.

An optical device is provided. The optical device includes a time-of-flight (TOF) sensor array, a photon conversion thin film, and a light source. The photon conversion thin film is disposed above the time-of-flight sensor array. The light source emits light with a first wavelength towards the photon conversion thin film to be converted into light with a second wavelength received by the time-of-flight sensor array. The second wavelength is longer than the first wavelength.

An outer surface of a casing (100) is provided with a first shape portion (152) and a second shape portion (154). The first shape portion (152) and the second shape portion (154) are engageable with other shape portions located outside the casing (100). The first shape portion (152) and the second shape portion (154) are aligned on the same straight line as a virtual straight line passing through the center of a field of view when viewed from a direction perpendicular to a direction in which the field of view expands. Alternatively, the first shape portion (152) and the second shape portion (154) may be aligned along a direction parallel to this straight line when viewed from the direction perpendicular to the direction in which the field of view expands.

An optical device (100) has a field of view (F) which enlarges as advancing toward one direction from a predetermined position. A housing (200) includes a transmission unit (210). The transmission unit (210) crosses the field of view (F). The housing (200) accommodates the optical device (100). The transmission unit (210) includes a first side (212) and a second side (214). The second side (214) is located on an opposite side to the first side (212). A width of the transmission unit (210) on a side with the second side (214) is narrower than a width of the transmission unit (210) on a side with the first side (212). The second side (214) of the transmission unit (210) is located closer to the predetermined position in the one direction than the first side (212) of the transmission unit (210).

A flexible substrate includes a heater portion and a wiring portion. A heater wire is formed in the heater portion. The heater portion is fixed to a transparent window. In the wiring portion, a wiring to the heater wire is formed. The wiring portion extends to a rear side of a casing in a case where a side on which the transparent window is provided in the casing is set as a front side. A fixing member fixes the wiring portion within the casing. A light shielding member is constituted to shield stray light from the fixing member toward a detection unit.

A distance measurement apparatus measures a distance to an object by irradiating emission light and detecting reflected light from the object onto which the emission light is irradiated. This apparatus includes a transmission window, a heater wire, and a flexible substrate that is provided in the transmission window. The flexible substrate includes: a surface-mounted-type electronic component; a land to which an electrode of the electronic component is electrically connected, and a conductive adhesive that is formed on the land and adheres the electrode of the electronic component and the land. When a longitudinal direction of a surface of the electronic component that opposes the land is a reference direction, a length along the reference direction of a contact surface between the land and the conductive adhesive is equal to or greater than twice a length along the reference direction of a mounting surface of the electrode of the electronic component.

An example apparatus may include a first plate having a first side. A first plurality of fins may be integral with the first side of the first plate and protruding perpendicularly therefrom. The first plurality of fins may be arranged in first concentric circles separated radially by a first distance. The apparatus may also include a second plate having a first side. The second plate may be rotatably coupled to the first plate. A second plurality of fins may be integral with the first side of the second plate and protruding perpendicularly therefrom. The second plurality of fins may be arranged in second concentric circles separated radially by the first distance. Each fin of the second plurality of fins may interpose between adjacent fins of the first plurality of fins to transfer heat between the second plate and the first plate.
