Technical Field
The invention relates to the field of laser radar visual axis monitoring devices, in particular to a laser radar visual axis monitoring device.
Background
The laser radar is a device that irradiates a measured object with laser light, receives a reflected light signal of the measured object, and estimates the properties of the measured object or other related objects by analyzing information such as intensity, wavelength, frequency, and time of the received reflected light signal. The measured object can be a solid substance such as a building, a human body, a vehicle, an airplane and the like, and can also be a substance with small volume such as dust, cells, and even molecules and atoms.
The optical receiving system has a certain receiving range or a certain receiving visual field, and reflected light signals outside the receiving range or outside the receiving visual field cannot be received; the receiving range is generally limited by the diameter of a light-transmitting small hole at the focus of a receiving system, the smaller the small hole is, the smaller the receiving field of view is, and the light-transmitting small hole is called as a small hole diaphragm; it is generally desirable to have the receive field of view as small as possible to compress the background light noise. The geometric central axis of the receiving field of view is referred to as the receiving system optical axis or receiving visual axis. The geometric central axis of the emitted laser light is called the emission axis. To ensure the reflected signal light is received, the emitted laser light must be within the receiving field of view of the optical receiving system, i.e., the alignment of the emission axis and the receiving field of view. (similarly, recording with a camera in the dark (optical receiver system), illuminating with a searchlight (lasing), and looking in the same direction as the camera and searchlight to capture an image.)
In lidar, the transmit axis is typically adjusted to the center of the receive field of view and fixed to ensure optimal alignment of the transmit and receive boresight. However, the deformation (including gravity deformation, stress release deformation, thermal expansion and contraction deformation, or deformation of the optical lens due to temperature change) which cannot be avoided by the fixing device or the laser or the optical receiving system causes the gradual maladjustment of the transmitting axis and the receiving field of view, and the reflected light signals cannot be effectively received, thereby affecting the reliability of the measurement result.
In order to solve the above problems, a set of device is needed to monitor the alignment condition of the transmitting axis and the receiving visual axis, so as to obtain the direction and degree of the transmitting axis deviating from the receiving visual field, and then feed the direction and degree back to the adjusting device of the transmitting axis or the receiving visual field, and adjust the transmitting axis and the receiving visual field to the optimal alignment position.
