    摘要: An electro-optic modulator comprises a waveguide (2) of a nonlinear optical material and an electrode line (3) for generating an electrical field in a modulating region (17) of the waveguide (2) when a voltage is applied to the electrode line (3). thereby modulating light passing through the waveguide (2). Therein ▪ the forward electro-optic response of the modulating region (17) is the same as the backward electro-optic response; and ▪ the electro-optic response has a band-pass or a low-pass characteristic. A distance measuring device comprises a light source (101) emitting light, and such an electro-optic modulator arranged such that the emitted Light passes through the electro-optic modulator in a first direction before being emitted from the distance measuring device, and after being reflected from a target passes through the electro-optic modulator in a second direction which is opposite to the first direction.

    摘要: Provided are a three-dimensional (3D) image acquisition apparatus, and a method of generating a depth image in the 3D image acquisition apparatus. The method may include sequentially projecting a light transmission signal, which is generated from a light source, to a subject, modulating reflected light, which is reflected by the subject, using a light modulation signal, calculating a phase delay using a combination of a first plurality of images of two groups, from among a second plurality of images of all groups obtained by capturing the modulated reflected light, and generating a depth image based on the phase delay.
