3. Plane mirror - Wikipedia

   en.wikipedia.org/wiki/Plane_mirror

   A ray diagram for a plane mirror. The incident light rays from the object create an apparent mirror image for the observer. A plane mirror is made using some highly reflecting and polished surface such as a silver or aluminium surface in a process called silvering. [6] After silvering, a thin layer of red lead oxide is applied at the back of ...

4. Ronchi test - Wikipedia

   en.wikipedia.org/wiki/Ronchi_test

   The Ronchi grating is a short distance (less than 2 cm) closer to the mirror. [citation needed] The observer sees the mirror covered in a pattern of stripes that reveal the shape of the mirror. The pattern is compared to a mathematically generated diagram (usually done on a computer today) of what it should look like for a given figure.

5. Ray transfer matrix analysis - Wikipedia

   en.wikipedia.org/wiki/Ray_transfer_matrix_analysis

   Each optical element (surface, interface, mirror, or beam travel) is described by a 2 × 2 ray transfer matrix which operates on a vector describing an incoming light ray to calculate the outgoing ray. Multiplication of the successive matrices thus yields a concise ray transfer matrix describing the entire optical system.

6. Virtual image - Wikipedia

   en.wikipedia.org/wiki/Virtual_image

   The image in a plane mirror is not magnified (that is, the image is the same size as the object) and appears to be as far behind the mirror as the object is in front of the mirror. A diverging lens (one that is thicker at the edges than the middle) or a concave mirror forms a virtual image. Such an image is reduced in size when compared to the ...

7. List of ray tracing software - Wikipedia

   en.wikipedia.org/wiki/List_of_ray_tracing_software

   Ray tracing is a technique that can generate near photo-realistic computer images. A wide range of free software and commercial software is available for producing these images. This article lists notable ray-tracing software.
