Abstract: An imaging device includes an imaging unit, a lens unit including a plurality of lenses stacked on each other to guide light to the imaging unit, a heater member used for a heater configured to heat a top lens closest to an object among the lenses included in the lens unit, and a reflection suppressor disposed between a region outside of an effective region of the top lens and the heater member, the reflection suppressor being configured to suppress light reflection. The reflection suppressor includes a first reflection suppressor disposed on the top lens side and having an uneven surface, and a second reflection suppressor disposed on the heater member side, the first reflection suppressor being layered on the second reflection suppressor. A surface of the second reflection suppressor facing the heater member is smoother than a surface of the second reflection suppressor facing the first reflection suppressor.

Abstract: An information acquiring device includes a projecting portion which projects a laser light emitted from a laser light source onto a target area, and a light receiving portion which receives the laser light reflected on the target area. The light receiving portion includes a color image sensor. The color image sensor has characteristics such that a detection sensitivity of a pixel that detects light of a predetermined color gradually decreases, and detection sensitivities of pixels that detect light of colors other than the predetermined color respectively have local maximum values on a long wavelength side than a visible light region, the detection sensitivities of the respective pixels substantially coinciding with each other in a wavelength band near a wavelength at which the local maximum values are given. An emission wavelength of the laser light source is set to a wavelength in the wavelength band.

Abstract: An information acquiring device has a light source which emits light in a predetermined wavelength band; a projection optical system which projects the light emitted from the light source toward a target area; and a light receiving element which receives reflected light reflected on the target area for outputting a signal. First signal value information relating to a value of a signal outputted from the light receiving element during a period when the light is emitted from the light source, and second signal value information relating to a value of a signal outputted from the light receiving element during a period when the light is not emitted from the light source are stored in a storage. An information acquiring section acquires three-dimensional information of an object in the target area, based on a subtraction result obtained by subtracting the second signal value information from the first signal value information stored in the storage.

Abstract: A projection optical system is provided with a diffractive optical element which converts laser light emitted from a laser light source into light having a dot pattern by diffraction and projects laser light onto a target area with a predetermined dot pattern. The diffractive optical element is formed in such a manner that the density of dots in a peripheral portion of a target area is set larger than the density of dots in a center portion of the target area. With this arrangement, in performing a pattern matching operation for a segment area in the vicinity of the outer side of the target area, the number of dots to be included in the segment area increases. This enhances the precision in the pattern matching operation.

A light diffractive portion for converting the laser light into laser light having a dot pattern by diffraction is integrally formed on a light exit surface of the collimator lens.

Abstract: Laser light emitted from a laser light source is converted into light having a dot pattern by a projection optical system for projection onto a target area. The projection optical system is configured such that the density of dots in a peripheral portion of the dot pattern is smaller than that in a center portion of the dot pattern in the target area. A dot pattern captured by irradiating a dot pattern onto a reference plane is divided into segment areas. A distance to each segment area is acquired by matching between dots in each segment area, and a dot pattern acquired by capturing an image of the target area at the time of distance measurement. The segment areas are set such that a segment area in the peripheral portion of the dot pattern is larger than a segment area in the center portion of the dot pattern.
