摘要： A range-finding device including a light-emitting device, an imaging unit, a calculator, and a controller. The image unit receives pulsed light reflected from an object within the space for a plurality of time periods in a time-division manner, electrically converts the pulsed light into an electrical signal, and accumulates electric charge of the electrical signal for each of the plurality of time periods. The calculator calculates a time difference between emission of the pulsed light and reception of the pulsed light reflected from the object based on the electric charge accumulated for each of the plurality of time periods and determine a distance to the object based on the time difference. The controller controls the timing of reception of the pulsed light for each of the plurality of time periods at the imaging unit according to an intensity of the pulsed light reflected from the object.

摘要： A range finding apparatus includes a light emission unit including a light source and a light source driver, a light detection unit, and circuitry. The light source driver supplies a plurality of drive pulses having different pulse width at different time periods. The light detection unit receives the light emitted from the light emission unit and then reflected from an object. The circuitry calculates a range to the object based on a time difference between one time point when a pulse light is emitted from the light source and another time point when light reflected from the object is received by the light detection unit. One of the drive pulses set with a smaller pulse width is set with a sine wave pattern, and another one of the drive pulses set with a greater pulse width is set with a rectangular wave pattern.

摘要： An inclination detecting device includes processing circuitry. The processing circuitry is configured to detect, in image information that is an image of an object imaged by an imaging device at an imaging position where a background member forms a background, a first boundary between the background member and a shadow of the object at detection positions in at least one of main-scanning and sub-scanning directions on an outline of the object; detect a second boundary between the object and the shadow of the object at detection positions in at least one of the main-scanning and sub-scanning directions on the outline of the object in the image information; detect a boundary group including detection results of the second boundary at the detection positions; and detect an inclination of the object in the image information from detection results of the first boundary, the second boundary, and the boundary group.

摘要： A light guide includes: a light guide board configured to allow light incident on an optical entrance to propagate through the light guide board, the light guide board including: the optical entrance; a first face; and at least one partial reflection layer within the light guide board and tilted to the first face. The at least one partial reflection layer is configured to reflect a part of light incident on the at least one partial reflection layer at an incident angle of greater than or equal to a critical angle θr to allow the reflected light to exit the light guide board through the first surface while transmitting therethrough a remainder of the light incident on the at least one partial reflection layer. Formula below is satisfied: θr=sin−1(n2/n1) where θr is the critical angle; n1 is a refractive index of the light guide board; and n2 is a refractive index of the at least one partial reflection layer.
