In the mounting base 113, a photovoltaic module is fixed, which will be described in detail below in conjunction with fig. 5 and 6. For clarity, the laser module frame 113 is omitted from FIG. 6, and only the optoelectronic components are shown. The photoelectric component comprises: the device comprises a laser emitting device, a laser receiving device and a reference point indicating device. Wherein, laser emission device includes: a laser transmitter 101 for transmitting a laser beam; a first total reflection mirror 102 for totally reflecting the laser beam; a first laser focusing lens 103 for converging the laser beams to form a collimated ranging laser; a band-pass filter 104 for allowing the ranging laser to pass and blocking natural light from passing; and a Dichroic mirror (Dichroic Mirrors)105 for reflecting the ranging laser light and allowing natural light to pass through. The laser receiving device includes: a dichroic mirror 105 for reflecting the ranging laser light and allowing natural light to pass therethrough; a band-pass filter 104 for allowing the ranging laser to pass and blocking natural light from passing; the second laser focusing lens 108 is used for converging the returned ranging laser; the second total reflection mirror 107 is used for totally reflecting the converged ranging laser; and a laser receiver 106 for converting the received optical signal into an electrical signal. Preferably, the laser light emitting device and the laser light receiving device share the dichroic mirror 105 and the band-pass filter 104. The reference point indicating device includes: a light emitting diode 109 for generating a visible indication light source; a diaphragm 110 for limiting a light emitting aperture of the visible indication light source; a reflecting mirror 111 for reflecting the visible indication light source passing through the diaphragm; and a concave focusing lens 112 for converging the visible indicating light source into a real image point, i.e., an indicating reference point.
The laser transmitter 101 and the laser receiver 106 are fixed below the cylindrical structure of the mounting base 113, and preferably, the laser transmitter 101 and the laser receiver 106 are arranged in parallel with the same distance from the bottom of the cylindrical structure.

The band pass filter 104 is located above the first laser focusing lens 103 and the second laser focusing lens 108, preferably also arranged at the bottom of the cylindrical structure. A dichroic mirror 105 is arranged above the bandpass filter 104, is fixed obliquely inside the cylindrical structure of the mount 113 and divides the inner space of the cylindrical structure into two parts. A concave focus lens 112 is fixed on the rear side (i.e., the right side as viewed in fig. 5) surface of the dichroic mirror 105. A light emitting diode 109 and a reflecting mirror 111 are fixed to the bottom of the cylindrical structure of the mount 113 at the rear of the dichroic mirror 105 (i.e., to the right as viewed in fig. 5), and a diaphragm 110 is disposed on the front side of the light emitting diode 109 and between the light emitting diode 109 and the reflecting mirror 111.
The resulting optical paths of the above described optoelectronic assembly will be described in detail below with reference to fig. 7a and 7b, where fig. 7a and 7b each show only the elements required to complete the respective optical paths.
Referring to fig. 7a, the optical path of the laser emitting device (left side) and the optical path of the reference point indicating device (right side) are shown simultaneously, which do not interfere with each other. The optical path (left side) of the laser emitting device is described first. The laser emitter 101 emits a laser beam having a specific wavelength band (for example, a wavelength band of 905 nm), which is totally reflected by the first total reflection mirror 102, passes through the first laser focusing lens 103 and then converges to form a collimated distance measuring laser, which passes through the band pass filter 104, reaches the dichroic mirror 105 and then is reflected to a specified target. The distance measuring laser is reflected after reaching the designated target object, part of the reflected distance measuring laser returns to the laser distance meter again to form a light path of the laser receiving device, referring to fig. 7b, the dichroic mirror 105 reflects, then sequentially passes through the band-pass filter 104 and the second laser focusing lens 108, and then reflects after reaching the second total reflector 107, and finally reaches the laser receiver 106, and the laser receiver 106 converts the received optical signal into an electrical signal. Thereby, the distance between the target object and the laser distance measuring instrument is measured. Here, since the dichroic mirror 105 is set to allow only natural light to pass through, the ranging laser light cannot enter the area behind the dichroic mirror 105 through the dichroic mirror 105. In addition, due to the arrangement of the band-pass filter 104, light with other wave bands except the ranging laser entering the mounting seat 113 cannot be received by the laser receiver, and interference of other light rays on distance measurement is avoided.
In addition, referring again to fig. 7a, an optical path of the reference point indicating device is also provided behind the dichroic mirror 105 (i.e., on the right side of fig. 7 a). Specifically, the light emitting diode 109 generates a visible indication light source, limits the light emitting aperture of the visible indication light source through the aperture plate 110, and then emits the light to the reflector 111 to be reflected, and then the light is reflected by the concave focusing lens 112 and converged at a certain point, so as to generate a real image of a light source point, i.e., an indication reference point. As shown in fig. 7a, the optical path of the reference point indicating device is set so that the optical axis of the indicating reference point and the optical axis of the ranging laser light directed to the target object are disposed on the same straight line, and thus the indicating reference point is also referred to as a laser indicating reference point. The laser indication reference point can be collected by the imaging device installed at the rear end of the laser range finder 100 at the rear together with the natural light, so that the position where the laser indication reference point observed by the imaging device by the user is superimposed on the natural light imaging is the position to which the ranging laser is actually directed, and the target object can be aimed.
Referring to fig. 8, it shows a laser range finder apparatus according to the present invention, which includes an imaging device and a laser range finder 100 according to the present invention fixed at the front end of the lens of the imaging device. Fig. 8a to 8c show three different embodiments of a laser rangefinder apparatus according to the present invention, wherein the laser rangefinder 100 is assembled with a white sight 300, a digital camera 400 and a cell phone 500, respectively.
Taking the embodiment shown in fig. 8b as an example, the laser ranging apparatus includes a digital camera 400 and a laser range finder 100 fixed to the front end of the lens thereof, and the use and operation process of the laser ranging apparatus according to the present invention will be described in detail. The light emitting diode 109 is turned on by the control button 202 so that a laser indicating reference point is formed in front of the lens of the digital video camera 400, the laser indicating reference point being collected by the lens together with natural light, and thus an image on the display of the digital video camera 400 has a red dot, i.e., the laser indicating reference point. Thus, the position of the laser pointer reference point in the image displayed on the display is the position at which the ranging laser is actually pointed. The aiming action can now be accomplished by rotating the vertical adjustment screw 206 and the horizontal adjustment screw 208 to move the laser pointer reference point, and/or by moving the image in the display of the digital camera 400 so that the red dot coincides with the target in the display. The aiming action can also be accomplished by moving the laser pointer reference point to the center of the screen of the display by rotating the vertical adjustment screw 206 and the horizontal adjustment screw 208 so that the aiming center of the laser rangefinder 100 coincides with the aiming center of the digital video camera 400 and then moving the device and apparatus as a whole. After aiming at the target object, the control key 202 is triggered to drive the main control circuit board 114 to generate a signal, the laser transmitter 101 receives the signal and then transmits a laser beam, the laser beam forms ranging laser after passing through the optical element, the ranging laser is emitted to the target object and reflected back, the laser receiver 106 converts the received optical signal into an electrical signal, and the electrical signal is transmitted to the main control circuit board 114. The main control circuit board 114 processes the electrical signals and then transmits the processed data to the display 203 to directly display the measurement result. Preferably, the electrical signals from the orientation sensor, the angle sensor, the temperature sensor, the humidity sensor, the barometric pressure sensor and the wind speed and direction sensor 205 are also transmitted to the main control circuit board 114 for processing, and the processed result can also be displayed on the display 203. Preferably, the laser ranging data of the laser range finder 100 and the measurement data of the sensor may also be transmitted to the digital video camera 400 at the rear end through an external interface or a wireless transmission module on the main control circuit board 114 for processing, and the processed measurement result may be directly displayed on the display of the digital video camera 400. That is, the laser range finder 100 may process data and display the measurement result by itself, or may transmit the data to the imaging device at the back end for processing and display the measurement result by the imaging device.
The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
