A laser radar includes: a light source including a laser diode; an optical system configured to shape laser light emitted from the laser diode, into a line beam that is long in one direction, and project the line beam to a target area; and a scanner configured to perform scanning with the line beam in a short side direction of the line beam. The laser diode is disposed such that a fast axis of the laser diode extends along a direction corresponding to the short side direction of the line beam.

The present invention relates to an optical device that enables the projection of the light to be controlled such that it comes out parallel to a non-active multi-cell shielding device, wherein said shielding device is not illuminated by the light beam, the user perceiving the light with all its intensity, without loss of intensity due to the reflection of said shielding device, wherein furthermore, due to the low profile thereof, the optical device enables same to be integrated into a luminaire with a reduced height dimension, which is also object of the present invention.

The present invention relates to ultrafast laser inscribed structures for signal concentration in focal plan arrays, focal plan arrays, imaging and/or sensing apparatuses comprising said focal plan arrays, as well as methods of making and/or using ultrafast laser inscribed structures for signal concentration in focal plan arrays, focal plan arrays, imaging and/or sensing apparatuses comprising said focal plan arrays. Such ultrafast laser inscribed structures are particularly adapted to condense broad band radiation, thus allowing increased sensing efficiencies to be obtained from imaging and/or sensing apparatuses.

An optical assembly is disclosed. The optical assembly includes a collimating lens which collimates a divergent laser beam. A conical mirror has a reflecting cover surface and deforms a laser beam, which propogates in the direction of the conical axis, into an annular beam in a propogation plane perpendicular to the conical axis. An optics carrier has a first carrier element on which the collimating lens is fixed and a second carrier element on which the conical mirror is fixed. A connection device has at least one connection element which connects the first and second carrier elements to one another. The at least one connection element is arranged askew to the conical axis of the conical mirror.

A photovoltaic (“PV”) module may comprise an array of freeform micro-optics and an array of PV cells. The PV module may be a flat panel with a nominal thickness smaller than the length and width of the flat panel. An array of lenses may be embedded in an array substrate. The lenses may be coupled to light pipes. The lenses may concentrate light through the light pipes to multi-junction cells. Diffuse light may be transferred through the array substrate to a silicon cell. The lenses and light pipes may be manufactured using a molding and drawing process.

Apparatus and methods for altering one or more spectral, spatial, or temporal characteristics of a light-emitting device are disclosed. Generally, such apparatus may include a volume Bragg grating (VBG) element that receives input light generated by a light-emitting device, conditions one or more characteristics of the input light, and causes the light-emitting device to generate light having the one or more characteristics of the conditioned light.

A lens diffusing light emitted from a light source includes a concave light-incident surface, a light guide portion, and a light-emitting surface. The light-incident surface includes a plane portion opposed to the light source and an optical function portion that is formed on the plane portion and one of scatters and diffuses the light. The light emitted from the light source enters the light-incident surface. The light that has entered the light-incident surface passes through the light guide portion. The light-emitting surface emits the light passed through the light guide portion.

A HUD system and light source apparatus can be manufactured with miniaturization at low cost. A head-up display apparatus includes: an image display apparatus generating image light to be projected; an optical system performing predetermined correction to the image light emitted from the image display apparatus; and a concave mirror reflecting the image light corrected by the optical system to project it onto a windshield or combiner. The image display apparatus includes: a solid light source; a collimating optical system converting, into parallel light, the light from the solid light source; a lighting optical system configured by an optical member that polarizes a direction of a light beam generated by the collimating optical system and simultaneously expands a width of the light beam; and a display apparatus, the image display apparatus being configured to be arranged across and opposite the optical system on an optical axis of the concave mirror.
