Dot-matrix Glass Photoresist

Photosensitive Glass Master of 'Original' general design. It's 2D/3D two layers. One color foreground and two color background.

Photosensitive Glass Master. It's 2D/3D three layers. One color foreground , one color background and one color floating.

This is silver layer coated photosensitive glass master photo of above glass master. After silvering, glass get conducting, so we can put it into electronic forming tank to make master origination.

A laser is used to illuminate the physical object, with the reflected light falling on the photoresist plate. Simultaneously, a reference beam from the laser also falls directly on the photoresist plate. The interference patterns of these two light beams react with the photo-sensitive coating to record a holographic image of the object. Common exposure times are between one to 60 seconds. In photography, slight motion of the object or the film results in a blurred image. In holography, however, the exposed plate will be blank (contain no image at all) if during the exposure there is movement as small as one fourth the wavelength of the laser light (wavelengths of visible light range from 400 to 700 billionths of a meter). A typical photoresist plate has a 6 in (15.24 cm) square working area; an extra half-inch (1.25 cm) of space on two edges allows the plate to be clamped into position. Because many holograms are smaller than this, several different images can be "ganged" (clustered) onto one plate, just as numerous individual photographs are exposed on one roll of film. The plate on which the original hologram is recorded is called the master. After being exposed, the master is processed in a chemical bath using standard photographic developers. Before proceeding with production, the master is inspected to confirm that the image has been properly recorded. Because of the chemical reactions caused by the laser and the developer on the photoresist, the developed plate's surface resembles the surface of a phonograph record; there are about 15,000 grooves per inch (600 per cm), reaching a depth of about 0.3 microns (1 micron is a thousandth of a millimeter).
