摘要： Image capturing accuracy is improved while a simple optical system is used. An image capture device includes: a polarizing filter that blocks non-transmitted light that has been in polarized light of an infrared ray radiated from a light source and has not been transmitted through an image capturing target and transmitted light that has been in the polarized light and has been transmitted through the image capturing target without diffusion inside the image capturing target, and transmits transmitted light that has been in the polarized light and has been diffused inside the image capturing target and transmitted therethrough; and an image sensor that receives the light that has been transmitted through the polarizing filter and captures an image of the image capturing target.

摘要： Light emission efficiency is increased in an eye-safe light source by regulating light distribution properties. An eye-safe light source includes a package, a semiconductor laser that emits laser light from a left light emission end surface and a right light emission end surface, and a wire that is joined to the semiconductor laser. The semiconductor laser is joined to the package such that the laser light is emitted parallel to an upper surface of a lead frame of the package. The package includes reflection surfaces that face the left light emission end surface and the right light emission end surface and reflect the laser light. In top view, a direction in which the wire extends is perpendicular to a direction of emission of the laser light.

摘要： An eye-safe light source that has a long lifetime and includes a lid which is not easily separated from a container is implemented. A transparent resin layer that seals a semiconductor laser fixes a cover to a package. A recess part that includes a bottom surface on which the semiconductor laser is mounted, a reflective surface on which laser light is reflected, and an opening through which the reflected laser light is radiated is disposed in the package. The cover covers the opening, and the transparent resin layer is disposed in the recess part.

摘要： Provided is an imaging device capable of improving imaging accuracy while suppressing increase in a size of the device and cost thereof. An imaging device includes: a light source which is a semiconductor laser that radiates infrared light to an imaging target; a polarizing filter that blocks light that is reflected by a surface of the imaging target and transmits light that is reflected inside the imaging target; and an image sensor that receives the light that is transmitted through the polarizing filter and captures an image of the imaging target.
