Disclosed herein is a projector for illuminating at least one object with at least one illumination pattern. The projector includes at least one array of vertical-cavity surface-emitting lasers (VCSELs). Each of the VCSELs is configured for generating at least one light beam. The projector includes at least one optical system configured for generating a characteristic beam profile for each of the light beams generated by the VCSELs of the array. The beam profile of neighboring VCSELs of the array differs in lateral and/or axial direction such that light beams of the VCSELs of the array are assignable to the corresponding VCSEL in three-dimensional space.

A system for measuring a length of a work piece including a leveling fixture disposed at a first end of the work piece and a range target disposed at a second end. The leveling fixture includes a precision stop abutting against the first end and range finders configured to be substantially aligned with the first end. The range target includes a target stop abutting against the second end and a vertical portion substantially aligned with the second end when the target stop abuts the second end. The range finders are each configured to take measurements between the range finders and the vertical portion of the range target so as to provide a measurement of the length of the work piece.

To provide a color identification method capable of identifying a color-coded color region by a simple method. By using a method for measuring a distance to an object to be measured based on a principle of triangulation by using LED light, irradiating a position where a color of a color-coded plane changes with the LED light, receiving reflected light by a light receiving unit provided in a direction same as a direction where the color of the plane changes, and comparing an output signal from the light receiving unit at that time with an output signal obtained from the light receiving unit when a position where a color does not change is irradiated with the LED light, it is possible to identify a color change position of the color-coded plane.

A parameter adjustment device (500) adjusts a parameter relating to control of laser light emitted from a measurement sensor (210) onto an object. A parameter calculator (520) calculates the parameter by applying, to a trained model generated through machine learning using training data sets each including waveform data of an amount of light received by the measurement sensor (210) and data indicating the parameter used to acquire the waveform data, waveform data newly acquired in a new state. The parameter calculated by the parameter calculator (520) enables measurement of the object using the measurement sensor (210) in the new state. A parameter outputter (530) outputs data indicating the parameter calculated by the parameter calculator (520).

A sensor device has a metal sensor housing with a housing base coupled to a frame base of a metal optical frame. A device mounting plate is orthogonal to the frame base. A securing device secures an optical communication device to the device mounting plate. A barrel mounting channel has first and second sidewalls, each extending obliquely to the frame base and defining a linear translation pathway along the frame base for a metal lens barrel. A fastener secures the metal lens barrel to the first and second sidewalls. A glass lens is in contact with three protrusions extending outward from an inner annular surface of the lens barrel. The optical communication device is configured to be in optical communication with the lens and is secured in a particular position in a translation plane mutually defined by the device mounting plate and the optical communication device.
