SENSOR CONFIGURATION FOR SUBSTANTIAL SPACING FROM A SMALL APERTURE

摘要

The inventive sensor (30) device includes a support structure, a sensing element (15) mounted on the support substrate (60) for sensing optical radiation and generating an electrical output signal in response thereto, an d an encapsulant (62) encapsulating the sensing element (15) on the support structure. The encapsulant (62) being configured to define a lens portion (6 1) for focusing incident optical radiation onto an active surface of the sensin g element, and an optical radiation collector portion (53) surrounding the len s portion for collecting and redirecting optical radiation that is not inciden t the lens portion (61) onto the active surface of the sensing element (15). T he collector portion (53) may be a parabolic reflector that reflects incident light by total internal reflection. The sensor device (15) may be incorporat ed into an assembly including a diffuser (32) positioned across an aperture, and/or may be incorporated into a vehicle accessory such as a rearview mirro r assembly.
