    摘要： A drawing apparatus (1) includes a laser light source unit (20) configured to output laser light; a scanning mirror unit (31) configured to reflect and scan the laser light; a drawing control unit (121) configured to control an output value of the laser light of the laser light source unit (20) based on display image data so that a display image (61) is drawn by the laser light in a range scanned by the scanning mirror unit (31); and an output adjustment control unit (122) configured to control the laser light source unit (20) so that characteristic detection laser light for adjusting the output value is output outside a range in which the display image is drawn inside the range (7) scanned by the scanning mirror unit (31). The output adjustment control unit (122) controls the characteristic detection laser light to be output based on a display color at an end part of the display image (61).

    摘要： A heads up display (HUD (12)) system that includes a light source (14) configured to project an image (20), and a diffractive combiner (16). The diffractive combiner (16) includes one or more reflective volume phase gratings (RVPG (26)), each configured to reflect light from the light source (14) having a distinct wavelength toward a HUD viewer (22). Each RVPG (26) is also embossed with a pattern configured to diffract light at the distinct wavelength so the HUD viewer (22) can see an image (20) in a field of view (24) that passes through the diffractive combiner (16). By forming a diffractive combiner (16) with an RVPG (26) embossed with a particular pattern, the occurrence of rainbow artifacts on the surface of the diffractive combiner (16) caused by random sources of light is reduced.

    摘要： An optical device for partially reflecting a first set of light waves having a given polarization state and located within a given optical spectrum and within a first angular spectrum, and transmitting a second set of light waves having the same given polarization state and located within the same given optical spectrum and within a second angular spectrum comprises a first light-transmitting substrate having a surface (22). A dichroic coating is disposed on said surface (22) and angles located within said first angular spectrum are smaller than angles located within said second angular spectrum. The reflectivity by the coated surface (22) of said first set of light waves is higher than the reflectivity by the coated surface (22) of said second set of light waves.
