Description

The portable laser orientator

Technical field

The utility model is path and the facula position that is applicable to invisible modulating lasering beam, and than the portable laser orientator of under the high light background path and the facula position of visible modulating lasering beam being measured.It equally also is applicable to the measurement of other non-laser beam and location.Belong to the detecting laser beam technical field.

Background technology

At present,, adopt the equipment of laser emitting source more and more along with the development of photoelectric technologies such as laser, especially more general with the equipment that adopts the voice modulation lift-off technology.In order to make these equipment operate as normal and to be in optimum condition, people often need to determine emissive source whether normally luminous (comprising invisible light) and hot spot physical location.Common method has: receive visible light spot with the paper target under the low light conditions, whether observation exists and the present position; Then need use expensive night vision device to observe to invisible hot spot.

But at bias light more by force to observing visible light or being invisible light, light spot energy is very weak, and when the range transmission source was far away, sensing that light beam is possible and facula position place spatial dimension were bigger, will be difficult to judge, thereby the integral body that influences equipment is transferred mass metering and work efficiency.

Summary of the invention

The utility model provide a kind of highly sensitive, convenient and practical, cheap, be applicable to the portable laser orientator of surveying visible light or invisible light facula position.

The utility model is made up of photodetection chi and sounder two parts, and two electrode outputs of photodetection chi are connected with lead with two circuit input ends of sounder respectively.The photodetection chi is that one group of (5～10) silicon photocell is connected in proper order, vertically is welded on the strip circuit board, this circuit board places a rectangle can, its two ends are fixed on the can base plate with screw, base plate one end is shaped on a through wires hole, by the base plate through wires hole electric wire at silicon photocell group two ends is drawn.The position of corresponding every silicon photocell has the rectangle light hole on the front plate of can, and the protection side end panel is equipped with at the two ends of box, and in the outside of box plate one handle is housed, and is convenient to survey the operation of chi.

Sounder is made up of common amplifying circuit, loudspeaker and battery, and the modulation signal that the silicon photocell of photodetection chi produces is input to audio amplifier circuit through surveying chi two electrode outputs, lead and sounder two circuit input ends.When the photodetection chi receives modulating lasering beam in the space, convert ac signal to by silicon photocell, after note amplifier amplifies, in loudspeaker, sound, inform the detection situation.During operation,, just can easily find the hot spot position with photodetection chi aloft level or vertical moving.

The utility model has the advantages that: 1, can measure the particular location of modulated weakly visible light or invisible light hot spot and light spot shape, size rapidly; 2, simple in structure, cheap; 3, the large space environment uses in the open air, and is particularly convenient.

Fig. 3 is the utility model sounder circuit theory diagrams.

As shown in Figure 1, this laser positioning instrument is made up of photodetection chi 1 and sounder 4.Two electrode outputs, the 2 (O of photodetection chi 1 ₁Or O ₂) with two circuit input end interfaces, the 5 (I of sounder ₁With I ₂) directly link to each other by lead 3.

As shown in Figure 2, photodetection chi 1 of the present utility model is by one group of silicon photocell 6 order lontitudinal series and be welded in the can on the strip circuit board 7.Circuit board 7 is fixed on by two screws 8 on the base plate 10 of rectangle can, and an end of base plate 10 is shaped on a through wires hole 11, by base plate through wires hole 11 two output terminal electrode lead-in wires 12 of silicon photocell is drawn.The position of corresponding silicon photocell has rectangle light hole 13 on the front plate 9 of can.Defensive side end panel 14 is equipped with at the two ends of can.Portably use for convenience,, handle 15 is housed in the outside of can base plate 10.

As shown in Figure 3, the circuit of sounder 4 is a kind of General Audio amplifier circuits, adopts modal IC741 integrated package to make amplifier, by the modulation signal of silicon photocell 6 conversion through electrode output O ₁, O ₂Export, and be directly inputted to the circuit input end I of sounder 4 through lead 3 ₁, I ₂, again through C ₁, R ₁Be input to the end of oppisite phase I of IC741 ₂With in-phase end I ₃, the IC741 integrated package amplifies the back by I with signal ₆End output is through capacitor C ₄Coupling and drive loudspeaker YS send the interchange sound equipment.Amplifier Gain depends on R ₂/ R ₁, R here ₁, R ₂Get 2K Ω respectively and 200K Ω gets final product.Capacitor C ₂, C ₃And resistance R ₃, R ₄, R ₅Be used to the in-phase end of IC741 amplifier to set up stable working point.Power supply uses common 9V packed cell.If adopt other note amplifier, also can with the supporting use of photodetection chi.
