The present invention relates to a folding mirror, and more specifically, to an invention that enables easy portability and convenient use thereof, through the folding and opening of the mirror.

A folding mirror is disposed between the aspheric lenses, to reduce the depth of the enclosure, and an aspheric mirror (10) projects the image onto a TIR Fresnel projection screen.

The Foldaway Mirror is a mirror that can be quickly folded out and used in any room of the house.

A collapsible portable video display (100) is provided, which incorporates a mini-projector (130), a folding mirror (120), and a rear projection foldable screen (125).

Modularity is obtained by arranging a semi-reflecting (23) planar blade in one of the modules and by arranging a retractable mirror (33) in the other module.

The folding mirror (18) collimates excitation light (L1), which has been output from the laser diode (14), in a slow axis direction, and reflects the excitation light (L1).

The base block (30A) supports the microchip laser (12), the laser diode (14), the collimator lens (16), the folding mirror (18) and the condensing lens (20).

Its uniqueness is to have a retractable mirror on top allowing the operator to achieve self-portrait thanks to the electronic self-timer (valuable for lonely sailor...).
