Embodiment approach 1
[0022] First, use figure 1 The block diagram of FIG. 2 describes the configuration of the scanning headlight according to Embodiment 1 of the present invention.
[0023] The scanning headlight 100 has a pattern irradiation unit 110 and a control unit 120 .
[0024] The pattern irradiation unit 110 has a function of generating a continuous pattern of visible light (hereinafter referred to as a scanning pattern) and irradiating it to the environment ahead. Typically, the pattern irradiation unit 110 is disposed in or near a headlight unit of an automobile.
[0025] figure 2 A specific configuration example of the pattern irradiation unit 110 is shown. figure 2 (a) is a configuration example of the pattern irradiation unit 110 using a diffractive optical element (DOE:Differaction Optical Element). The pattern irradiation unit 110 includes a laser element 111 , a lens 112 , and a DOE 113 . The laser element 111 emits laser light. The lens 112 magnifies the laser light into...
Embodiment approach 2
[0038] In Embodiment 2, an example is shown in which instead of simply irradiating the scanning pattern to the front environment, the control unit 120 controls the pattern irradiation unit 110 by changing the irradiation form of the scanning pattern based on various conditions.
[0039] Preferably, the scanning headlight 100 of Embodiment 2 further includes an obstacle detection unit 130 that detects whether there is an obstacle in the environment ahead, and detects its position (for example, direction and distance) if there is an obstacle ( Image 6 ). The rest of the configuration is the same as that of Embodiment 1 unless otherwise mentioned.
[0040] An example of the operation of the scanning headlight 100 according to Embodiment 2 will be described below.
[0041] (a) Control of irradiation timing
[0042] First, the obstacle detection unit 130 detects that there is an obstacle in the environment ahead. For example, as described in Non-Patent Document 1, the method of...
