10 and 11 show a process in which a hologram corresponding to a screen image is recorded on a hologram medium 163a' to manufacture a first hologram device 163a, and a screen image is reproduced therefrom. The hologram corresponding to the screen image may be formed by, for example, recording the image of the diffuser 10 on the hologram medium 163a'. The hologram medium 163a' is a photosensitive medium sensitive to light, and is formed of a material such as photoresist or photopolymer, and an optical interference pattern between object light containing image data and reference light not containing data. image information can be stored. That is, when light is irradiated to the diffuser 10, an object light Lo containing image data of the diffuser 10 is emitted from the diffuser 10, and the object light Lo and a reference light that does not contain any image data An interference fringe formed by the interference of Lr1 is recorded on the hologram medium 163a'. In this case, a laser beam having good coherence is used as the light forming the reference light Lr1. In FIG. 11, the first hologram element 163a shows that the image hologram of the diffuser 10 spaced apart from the hologram medium 163a' by a distance d1 is recorded. When the first hologram element 163a is irradiated with the same reference light Lr1 as used for recording, the reference light Lr1 is diffracted by the hologram formed on the first hologram element 163a, whereby the object light Lo is is restored The restored object light Lo represents a diffuser image, which is equivalent to forming the screen S1 in a space spaced apart by a distance d1 from the first hologram element 163a.

12 and 13 show a process of manufacturing a second hologram device 163b by recording a hologram corresponding to a screen image on the hologram medium 163b', and reproducing a screen image therefrom. This time, after the diffuser 10 is spaced apart from the hologram medium 163b' by a distance d2, the object light Lo containing the image of the diffuser 10 and the reference light Lr2 not containing the image data are separated from the hologram medium 163b. ') to be investigated. In this case, the angle at which the reference light Lr2 is incident on the hologram medium 163b' is different from that of the reference light Lr1 in FIGS. 10 and 11 . An interference fringe formed by interference between the object light Lo and the reference light Lr2 is recorded on the hologram medium 163b'. In FIG. 13 , the second hologram element 163b shows that the image hologram of the diffuser located at the distance d2 is recorded in the hologram medium 163b' as described above. When the reference light Lr2 used for recording is irradiated to the second hologram element 163b, the object light Lo is restored and a screen S2 is formed at a location spaced apart from the second hologram element 163b by a distance d2.

The three-dimensional image display device 100 of this embodiment employs the first and second hologram elements 163a and 163b manufactured in the same way as described above. In principle, the hologram is reproduced only at the angle of the reference light used for recording. will use That is, the hologram shows maximum efficiency when reproduced at the same angle as the reference light during recording, and this angle is called the Bragg angle. In the graph of FIG. 15 showing the diffraction efficiency, the horizontal axis indicates the degree of deviation from the Bragg angle, and the vertical axis indicates the diffraction efficiency. Referring to the graph, it can be seen that there are cases in which the diffraction efficiency drops to zero as the Bragg angle deviates. When this principle is applied, when the angle of the illumination light is adjusted to match the Bragg angle when the hologram recorded in each of the first and second hologram elements 163a and 163b is reproduced, the first and second hologram elements 163a , 163b) overlapped, images recorded on each can be reproduced without mutual interference.

In the first and second light source units 161a and 161b, light is incident on each of the first and second hologram elements 163a and 163b at an angle corresponding to the reference light of each of the first and second hologram elements 163a and 163b. Lights are sequentially illuminated to Accordingly, the light imaged at different positions from the first and second hologram elements 163a and 163b is sequentially reproduced.

A holographic polymer dispersed liquid crystal (HPDLC) may be used as a hologram medium for forming the first and second hologram elements 163a and 163b constituting the above-described hologram optical unit 163 . Polymer dispersed liquid crystal (PDLC) is a material formed by dispersing a polymer in a liquid crystal cell, and has a property of being controlled in a transparent state and a diffusion state according to electrical control. In particular, it is known that a hologram image can be electrically switched when a hologram is recorded on an HPDLC formed by dispersing a photopolymer in a liquid crystal cell.

The display panel 164 modulates the light reproduced in this way by the hologram optical unit 163 according to an image signal to form an image, and may be composed of, for example, a liquid crystal panel. Since the first and second hologram elements 163a and 163b are disposed behind the display panel 164, the display panel 164 applies the light reproduced from the first and second hologram elements 163a and 163b to the image signal. modulate accordingly. The display panel 164 divides an image of one frame into a plurality of images and alternately implements them in a time multiplexing method. For example, an image of one frame is divided into two sub-frame images, and the display panel 164 modulates light according to a corresponding image signal. The two sub-frame images may be a background image I1 and a front image I2. The period in which the display panel 164 alternately implements the background image I1 and the front image I2 is recognized as an image of one frame, which should be shorter than the blinking of the eyes of the passenger or waiting for boarding, for example, 1/120 second shorter than As shown in the drawing for the front image I2, the background image I1 forms a sense of depth as much as d, which corresponds to the difference between d2 and d1, to the occupants or passengers waiting for boarding, whereby a three-dimensional image can be recognized.

For example, the light path changing unit 162 is the angle of the reference light used when the light from the first and second light source units (161a, 161b) to the first and second hologram elements (163a, 163b) to record the hologram. Convert the light path to have To this end, the optical path changing unit 162 may be formed of a Fresnel lens obliquely disposed with respect to the fixing plate 161c on which the first and second light source units 161a and 161b are mounted. The Fresnel lens serves to condense and collimate the light, and as shown in the figure, since the Fresnel lens is disposed at an angle with respect to the fixing plate 161c, the light from the first and second light source units 161a and 161b These different angles of incidence are incident on the Fresnel lens. Accordingly, the light from the first and second light source units 161a and 161b passes through the Fresnel lens 121 and then enters the hologram optical unit 163 at different angles. The degree of inclination of the Fresnel lens with respect to the fixing plate 161c may be appropriately determined in consideration of the reference light angle when the hologram is recorded on the first and second hologram elements 163a and 163b. In the drawings, one Fresnel lens has been illustrated and described as the optical path converting unit 162, but a plurality of path converting members respectively disposed on the optical paths from the first and second light source units 161a and 161b may be employed. In addition, a plurality of condensing lenses may be further provided. In addition, the rotational driving units 161d and 162a are mounted on the fixed ends of the fixed plate 161c and the optical path converting unit 162 to adjust the respective inclinations to an optimal state. (See FIG. 14 )

The control unit C controls the driving of the lighting unit 161 and the display panel 164, for example, in synchronization with sequentially modulating the image signals corresponding to the two sub-frame images in the display panel 164. The on/off of the first and second light source units 161a and 161b is controlled. In addition, as described above, when the first and second hologram elements 163a and 163b are made of a holographic polymer dispersed liquid crystal, the first and second hologram elements 163a and 163b are synchronized with the illumination signal and the image signal, respectively. to control switching.

As described above, along with the action of forming a plurality of screen images in the hologram optical unit 163, the occupant or the waiting person has a different sense of depth by d according to the synchronized driving of the display panel 164 and the lighting unit 161. sees two images (I1, I2) and recognizes a three-dimensional image. In addition, it is also possible to implement a general two-dimensional image by using only one of the plurality of light source units 161a and 161b constituting the lighting unit 161 and modulating light according to the two-dimensional image signal in the display panel 164 . do.

In this case, according to the present embodiment, by mounting the hologram optical unit, the display panel, and the optical path changing unit of a specific structure on the casil lamp and the hall sill lamp, a two-dimensional screen image or a three-dimensional screen image is realized while lighting in a specific color.
