Abstract:
Disclosed are an imaging optical system which can be manufactured in a reduced size to make the size of a 3D image acquisition device small and the 3D image acquisition device including the same. The disclosed imaging optical system comprises a common object lens; first and second image sensors having sizes different from each other; a beam splitter providing light for the first image sensor by transmitting part of light focused by the object lens and providing light for the second image sensor by reflecting the remaining part of the light; and at least one optical element disposed between the beam splitter and the second image sensor and reducing an image which is incident on the second image sensor. The optical element includes at least one among a Fresnel lens and a diffractive optical element. [Reference numerals] (105) Display; (106) Memory; (107) Control unit
Abstract:
PURPOSE: A transmissive image modulator having a laminated diode structure including a multi absorption mode is provided to reduce an operating voltage by half by supplying an N-I-P-I-N structure or a P-I-N-I-P structure which is a shape that two or more diodes are laminated in parallel. CONSTITUTION: A first active layer (120) is placed on a first reflective layer (110) and includes a plurality of quantum well layers and a plurality of barrier layers. A second reflective layer (130) is placed on the first active layer. A second active layer (140) is placed on the second reflective layer and includes a plurality of quantum well layers and a plurality of barrier layers. A third reflective layer (150) is placed on the second active layer. The first and the third reflective layers are doped in a first electrical type. The second reflective layer is doped in a second electrical type which is electrically opposite to the first electrical type.
Abstract:
PURPOSE: A transmissive image modulator using a mlulti-Fabry-perot resonant mode a multi-absorption mode is provided to improve transmittance all over large wavelength range with 'a resonant wavelength mode with more than three peaks' by forming multiple micro cavities on the upper mirror and the lower mirror of the image modulator in a PIN structure. CONSTITUTION: An active layer(120) is arranged on a lower distributed bragg reflector layer[lower DBR layer](110) and contains multiple quantum wells and multiple barrier layers. An upper DBR layer(130) is arranged on the active layer. At least one or more of the first micro cavity layer(111) is arranged in a lower reflective layer. At least one of more of the second micro cavity layer(131) is arranged in an upper reflective layer. If a resonant wavelength is λ, the active layer and at least one of the first micro cavity layer and the second micro cavity layer have optical thickness with the integer multiplication value of λ/2.
