Types of Reflection

Light as it hits an object:

  • Light interacts with a part in several ways

  • Conservation of energy principal:  energy changes in form, but the total amount remains constant

  • Understanding how reflection occurs helps to control "hot spots" and achieve even illumination

 

Types of reflection:

  1. Specular:  Smooth surfaces direct reflected light at opposite angle

  2. Diffused:  Rough surfaces scatter light in all directions

  3. Spread:  Some surfaces have a combination texture and smooth surface
