摘要： A hologram disc reading and writing apparatus including a signal light source module, a beam splitter, a reference/reading light source, a reflector, and an optical reading head and a hologram disc reading apparatus are provided. A signal light beam emitted from the signal light source module is transmitted to a data region of a hologram disc through the beam splitter. The reference/reading light source, the signal light source module, and the optical reading head are disposed at the same side of the hologram disc. The reflector is disposed at the other side. A spherical wave light beam emitted from the reference/reading light source is transmitted through the data region and reflected by the reflector to form a phase conjugate light beam transmitted to and through the data region. The phase conjugate light beam is transformed to a data light beam transmitted to the optical reading head through the beam splitter.

摘要： A light guide plate capable of guiding a light beam from a light emitting device and a backlight module using the light guide plate are provided. The light guide plate includes a light-transmissive substrate and optical structures. The light-transmissive substrate has a first surface, an opposite second surface, and an incident surface connecting the first and the second surface. The light beam enters the light-transmissive substrate through the incident surface and is emitted out of the light-transmissive substrate through the first surface. The optical structures are disposed on the second surface. Each optical structure has a first total internal reflection (TIR) surface, a second TIR surface, and a third TIR surface. The second TIR surface connects the first and third TIR surfaces. Part of the light beam from the incident surface is totally internally reflected by any adjacent two of the first, second, and third TIR surfaces in sequence.
