A LIDAR system includes a LIDAR assembly configured to output a LIDAR output signal that carries multiple different channels. A directional component has an optical grating that receives the LIDAR output signal from the LIDAR assembly. The directional component demultiplexes the LIDAR output signal into multiple LIDAR output channels that each carries a different one of the channels. The directional component is configured to steer a direction that the LIDAR output channels travel away from the LIDAR system.

The present invention relates to a multi-channel lidar sensor module capable of measuring at least two target objects using one image sensor. The multi-channel lidar sensor module according to an embodiment of the present invention includes at least one pair of light emitting units configured to emit laser beams and a light receiving unit formed between the at least one pair of emitting units and configured to receive at least one pair of reflected laser beams which are emitted from the at least one pair of light emitting units and reflected by target objects.

One example of an inspection system includes a laser, a magnification changer, and a first camera. The laser projects a line onto a wafer to be inspected. The magnification changer includes a plurality of selectable lenses of different magnification. The first camera images the line projected onto the wafer and outputs three-dimensional line data indicating the height of features of the wafer. Each lens of the magnification changer provides the same nominal focal plane position of the first camera with respect to the wafer.

It is intended to promote enhancement of performance of acquiring a depth image. A depth image acquiring apparatus includes a light emitting diode, a TOF sensor, and a filter. The light emitting diode irradiates modulated light toward a detection area becoming an area in which a depth image is to be acquired to detect a distance. The TOF sensor receives incident light into which the light irradiated from the light emitting diode is reflected by an object lying in the detection area to become, thereby outputting a signal used to produce the depth image. The filter passes more light having a wavelength in a predetermined pass bandwidth than light having a wavelength in a pass bandwidth other than the predetermined pass bandwidth of the light made incident toward the TOF sensor. In this case, at least one of the light emitting diode, the TOF sensor, or arrangement of the filter is controlled in accordance with a temperature of the light emitting diode or the TOF sensor. The present technique, for example, can be applied to a system for with international search report acquiring a depth image by using a TOF system.

A non-imaging concentrator is employed in an upside down configuration in which light enters a smaller aperture and exits a larger aperture. The input angle of light rays may be as large as 180 degrees, while the maximum exit angle is limited to the acceptance angle of the non-imaging concentrator. A dichroic filter placed at the larger aperture has a maximum angle of incidence equal to the acceptance angle of the non-imaging concentrator.

An apparatus includes a time-of-flight (TOF) sensor system that has an illuminator operable to emit pulses of light toward an object outside the apparatus. The illuminator is operable in a first mode in which the illuminator emits pulses having a first width and a second mode in which the illuminator emits pulses having a second width longer than the first width. The TOF sensor system further includes a photodetector operable to detect light produced by the illuminator and reflected by the object back toward the apparatus. An electronic control device is operable to control emission of light by the illuminator and is operable to estimate a distance to the object based on a time elapsed between an emission of one or more of the pulses by the illuminator and detection of the reflected light by the photodetector.

A solid-state lidar device comprises a laser generator, an optical lens arrangement having a focal length and providing a rear focal plane, a solid-state sensing array positioned at the rear focal plane of the optical lens arrangement having a first sensor and a second sensor spaced from each other by a first sensor distance and at least one processor. The processor is configured to obtain a measured distance of the target from a pulsed time-of-flight measurement utilizing the laser generator and at least one of the first sensor and the second sensor of the solid-state sensing array and obtain at least one spatial coordinate for the target from the measured distance using a calibration parameter indicative of the ratio of the first sensor distance and the focal length.

Distance measurement accuracy is improved while an increase in power consumption is suppressed. A solid-state imaging device includes a first pixel (210) that detects an address event based on incident light, and a second pixel (310) that generates information on a distance to an object based on the incident light. The second pixel generates the information on the distance to the object when the first pixel detects the address event.

A light receiving device of the present disclosure includes a light receiving unit that has a plurality of photon counting type light receiving elements arranged, the plurality of photon counting type light receiving elements receiving light from an object, an addition unit configured to add values of the plurality of light receiving elements at a predetermined time to use a resultant as a pixel value, and a logarithmic transformation processing unit configured to transform the pixel value into a logarithmic value or an approximate value thereof to use a resultant as logarithmic representation data, in which reflected pulsed light, from a subject, based on the photon counting type light receiving elements receiving light from the object from a light source unit is received.
