Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, this utility model is further described, but should not limited this with this
The protection domain of invention.
The direction detection instrument as it is shown in figure 1, a kind of polaroid shakes thoroughly, it is characterised in that include shell (1), shell (1) interior
Wall is provided with circuit of light sources (2), and the front of circuit of light sources (2) is provided with standard polarizer (3), the front of standard polarizer (3)
Being provided with prime delustring cylinder (4), the front of prime delustring cylinder (4) is provided with corner cube prism (5), and the top of corner cube prism (5) sets
Be equipped with rear class delustring cylinder (6), rear class delustring cylinder (6) be provided above slide glass turntable (7), being provided above of slide glass turntable (7)
Detection is had to process circuit (8).Being internally provided with and slide glass turntable (7) motor connected vertically (9) of shell (1)；Shell
(1) inwall is provided with display screen (10), battery (11).Wherein, described slide glass turntable (7) use transparent plastic to make and
Become；Described Photoelectric Detection processes circuit (8) and uses photodiode as detecting element.
As in figure 2 it is shown, the outer wall of shell (1) arranges power key (12), power interface (13), feet (14).Circuit of light sources
(2), Photoelectric Detection processes circuit (8), motor (9), display screen (10), battery (11), power key (12), power interface
(13) it is interconnected with one another by wire.
When using detector, polaroid to be measured (15) is placed on slide glass turntable (7), turns on the power key (12).Light source
The light that circuit (2) sends, after standard polarizer (3), becomes the polarized light of specific direction, through prime delustring cylinder (4), disappears
Remove impurity astigmatism, it is to avoid the interference to detection signal.Polarized light continues to corner cube prism (5), and corner cube prism (5) plays turnover light
The effect on road, so that whole detector compact conformation.The installation of corner cube prism and debug very convenient, also makes detector
Production cost reduces a lot.Polarized light after turnover eliminates veiling glare further by rear class delustring cylinder (6).Polarized light is by carrying
Sheet turntable (7) and polaroid to be measured (15), arrive detection and process circuit (8), the detected photodiode processing circuit or light
Battery probe is to optical signal, and then changes into the signal of telecommunication.Display screen (10) shows current detected state in real time.
As shown in Figures 2 and 3, slide glass turntable (7) slowly rotates one week under the drive of motor (9), Photoelectric Detection
Process the maximum Imax of the single-chip microcomputer record signal of telecommunication of circuit.Slide glass turntable (7) is rotated further, single-chip microcomputer real time record photoelectricity
Value I of signal, and compare with maximum Imax.When the difference of Imax Yu I is zero, illustrate that optical signal reaches the strongest, this
Shi Bujin motor stalls, now the direction indicated by direction signs (16) of detector is the saturating of polaroid to be measured (15)
Shake direction.
