An optical modulator intersects with the first and second beam splitters to modulate their phase. Lens assemblies are respectively disposed on a second and a third optical path to amplify and rotate the first split beam before projecting it onto a first region to form a first pattern. Lens assemblies amplify and rotate the second split beam before projecting it onto a second region to form a second pattern. The horizontal resolution of the first and second patterns is greater than their vertical resolution. The first and second patterns combine to form an elongated image.

The object image value for each location in the ultrasonic reflectance image is calculated by summing the image values ​​from images associated with selected intersections in different rows and columns within the array of ultrasonic transducers. The image value for each of these intersections is determined by transmitting an ultrasonic transmission signal from the ultrasonic transducer to a first subsampled selection of first sampling locations along the column of intersections, and at least partially simultaneously receiving reflections from a second subsampled selection of second sampling locations along the row of intersections. The image values ​​for different locations are calculated by combining the vertical resolution from the subsampled transmitted ultrasonic signal and the horizontal resolution from the subsampled received ultrasonic signal. The range of subsampling locations for each intersection has a large overlap with the subsampling range for adjacent intersections, and the subsampling locations for different intersections exist at least partially scattered amongst each other within that overlap. The extension of subsampling locations across a large overlapping range ensures high resolution in the intersection image, and the use of different sampling points within that overlap reduces artifacts in the summed image.

Object image values for each position in the image of ultrasound reflectivity are computed by summing image values from images associated with selected cross-points of different rows and columns in an array of ultrasound transducers. The image value for each of these cross points is determined by transmitting ultrasound transmission signals from the ultrasound transducers at a subsampled first selection of first sampling locations along the column of the cross point and receiving reflections at least partly simultaneously from a subsampled second selection of second sampling locations along the row of the cross point.

This invention discloses a method for measuring distance and velocity based on trapezoidal wave optical frequency-modulated continuous wave, including a target object, a lidar, and an analog-to-digital converter. The frequency value of the beat signal at the rising edge is denoted as f1, the frequency value at the falling edge as f2, and the frequency value of the beat signal in the invariant region as fd. The beat signal is sampled by a data acquisition card, yielding two main frequency values: f+ and f-, where f+ is the highest peak frequency and f- is the second highest peak frequency, i.e., f+ > f-. This method improves the range and velocity measurement limits without changing the hardware, without sacrificing horizontal resolution or frame rate. Furthermore, the sum of the highest Doppler frequency and the distance frequency that can be sampled is no longer limited by the Nyquist frequency, but can instead reach the sampling frequency of the analog-to-digital converter. The two trapezoidal waves used in this method are equivalent, and the waveforms are easy to implement.
