2. Lightbox - Wikipedia

   en.wikipedia.org/wiki/Lightbox

   A variation of this is a box, with one open end, made of diffusing material, to allow the photographing of a sample object with no shadows. It is also called light tent or photo cube. [8] A folder used on stock photography to allow a user to organize digital photos. Photos can be assigned to a viewable lightbox folder by subject, for later ...

   Where ultra-violet light is transmitted through the tracing paper, the light-sensitive coating converts to a stable blue or black dye. Where the India ink blocks the ultra-violet light the coating does not convert and remains soluble. The image can be seen forming. When a strong image is seen the frame is brought indoors to stop the process.

   Light table at Tito's bunker Draftsman using light table. A light table [1] is a viewing device that is used to review photographic film or artwork placed on top of it. A horizontal form of a self-standing lightbox, it provides even illumination of the subject from below through a translucent cover and fluorescent lights that emit little heat.

5. Structured-light 3D scanner - Wikipedia

   en.wikipedia.org/wiki/Structured-light_3D_scanner

   Patterns are usually generated by passing light through a digital spatial light modulator, typically based on one of the three currently most widespread digital projection technologies, transmissive liquid crystal, reflective liquid crystal on silicon (LCOS) or digital light processing (DLP; moving micro mirror) modulators, which have various ...

6. Digital light processing - Wikipedia

   en.wikipedia.org/wiki/Digital_Light_Processing

   Digital light processing (DLP) is a set of chipsets based on optical micro-electro-mechanical technology that uses a digital micromirror device. It was originally developed in 1987 by Larry Hornbeck of Texas Instruments. While the DLP imaging device was invented by Texas Instruments, the first DLP-based projector was introduced by Digital ...

7. Radiance (software) - Wikipedia

   en.wikipedia.org/wiki/Radiance_(software)

   It uses ray tracing to perform all lighting calculations, accelerated by the use of an octree data structure. It pioneered the concept of high-dynamic-range imaging , where light levels are (theoretically) open-ended values instead of a decimal proportion of a maximum (e.g. 0.0 to 1.0) or integer fraction of a maximum (0 to 255 / 255).
