    摘要： A method of synchronizing a first oscillation about a first axis with a second oscillation about a second axis includes: generating a first position signal that indicates a position of the first oscillation about the first axis; generating a second position signal that indicates a position of the second oscillation about the first axis; determining a phase difference between the first and the second position signals; comparing the phase difference to a threshold value to generate a comparison result; generating a first reference signal having a first frequency and a second reference signal having a second frequency; synchronizing the first oscillation to the first frequency and synchronizing the second oscillation to the second frequency; monitoring the comparison result; and synchronously triggering a start of the first reference signal and the second reference signal responsive to the comparison result indicating that the phase difference is less than the threshold value.

    摘要： An optical engine module including at least two laser sources, collimators, a light combining lens group, an aperture, a beam shaping lens group, a MEMS scanning module, and a beam expansion lens group is provided. The at least two laser sources respectively generate at least two laser beams with different wavelengths. The collimators respectively collimate the at least two laser beams to generate at least two collimated beams. The light combining lens group combines the at least two collimated beams into a combined beam. The aperture filters stray beams of the combined beam. The beam shaping lens group shapes the combined beam to generate a shaped beam with a perfect circle. The MEMS scanning module reflects the shaped beam and scans in horizontal and vertical directions to form a scanning beam. The beam expansion lens group expands the scanning beam into an expanded beam having a predetermined area.

    摘要： A method of data acquisition and image generation over a wide and dynamic time interval between surface scans using modified electrical waves is disclosed. It is also disclosed that generating altered electrical waveforms that drive a scanner using conventional waves such as sinusoidal or triangle or sawtooth can enhance the method. Systems for A-scan, B-scan, and C-scan imaging pp include surface scan setups using a one-dimensional and a two-dimensional scanner, respectively. Three different arrangements of conventional waves enable modified waveforms that drive scanners to produce a wide and dynamic interscans time interval on both the fast and slow scan axes. (i) At a constant peak-to-peak voltage, the instantaneous voltage of the electrical sinusoidal wave shifts in time with the amplitude of the electrical signal in the ramp waveform within a range. (ii) The frequency of a waveform continuously increases (up-chirp) as a function of time in the form of a positive ramp sawtooth or continuously decreases as a function of time in the form of a negative ramp sawtooth. (iii) The frequency of a waveform is modulated as a function of time in a 90-degree phase retarded sinusoidal form within a deviation range of the +/− peak frequency.

    摘要： An apparatus, comprising, a scan module having one or more laser sources that generate one or more initial laser beams and two or more beam deflectors that deflect the one or more initial laser beams. A beam optic is configured to substantially collimate the one or more initial laser beams to produce one or more collimated laser beams. One or more beam deflector controllers are configured to control an angle of beam deflection from each beam deflector. Relay optics between the two or more beam deflectors are configured to image each sequential beam deflector in an optical chain onto the subsequent beam deflector in such a manner that the beam deflecting from a last beam deflector in the optical chain contains a combination or superposition of all the beam deflections of the beam deflectors in the sequence, and maintains a beam divergence of the one or more collimated beams. A first beam deflector of the two or more beam deflectors is configured to scan about a single axis and a second beam deflector of the two or more beam deflectors is configured to scan in a quasi-static mode about two orthogonal axes.

    摘要： A picture generation system includes a plurality of red-green-blue (RGB) light transmitters configured to synchronously generate respective pixel light beams and transmit the respective pixel light beams along respective transmission paths to be projected into a full field of view (FOV). The full FOV is divided into a plurality of FOV sections that are respectively paired with a different one of the plurality of RGB light transmitters such that each of the plurality of RGB light transmitters transmits light into a respective area defined by its respective FOV section. The picture generation system further includes a scanning system arranged on each of the respective transmission paths of the plurality of RGB light transmitter. The scanning system includes a scanning structure that enables the scanning system to simultaneously steer the respective pixel light beams into the plurality of FOV sections.

    摘要： A mirror unit includes an optical scanning device, a frame member, and a window member. The frame member includes first and second wall portions facing each other in an X-axis direction. The first wall portion is higher than the second wall portion. The window member is disposed on a top surface of the first wall portion and a top surface of the second wall portion and is inclined with respect to a mirror surface of the optical scanning device. In a cross-section parallel to the X-axis direction, the first wall portion is separated from a first line passing through a first end at a side of the first wall portion in the mirror surface and a first corner portion formed at the side of the first wall portion by an outer surface opposite to the frame member and a first side surface in the window member.
