' See the 1 to 5 关于 for the photo sensor In the first embodiment of the present invention, the money sensing (four) domain measures the sensing n of different wavelength requirements, and the adjusting method comprises the following steps: (1) measuring the response of the photo sensor The spectrum (as shown in Fig. 2), wherein the photo-sensing device is a photodiode of the type Si material (the photodiode of the first material f), and the horizontal axis in the figure is wavelength. (2) Analyze the optical response ratio of the a-Hui response spectrum at different wavelengths (as shown in Fig. 3). The optical response ratio is: when the wavelength is 400, the optical response ratio is the pick; when the wavelength is milky The optical response ratio is 11%;...; when the wavelength is 95〇, the optical response ratio is 99%; when the wavelength is 1〇〇〇, the optical response ratio is 98%; when the wavelength is 1〇50, the optical response ratio is 63%. %; When the wavelength is 11 ,, the light response ratio is 17%. In other words, when the wavelength is between 400., the light response ratio is gradually increased, and when the wavelength is between 950 and up to 1100, the light response ratio is rapidly decreased. 5 201035528 (=, set 1 domain detector β branch. Its material 0 again. Ten, its - according to Figure 2, water and flowers are connected to the 'response spectrum to design' second, according to the light response ratio = The product system is designed to have a proportional relationship with the photocurrent output value. The third is to design the (4) light receiving _f this-丄xt basis, as shown in Fig. 3. The designed light receiving area Ο Ο When the ratio is iu%; ..;; the wavelength reading time product ratio is (10); when the wavelength is _, when the _ ratio is 2 agricultural wavelengths, the light receiving ratio is H)·5%. In other words, the pattern of the light-receiving area ratio (see Section 4(5) is the opposite of the light-response pattern (see Figure 3). (4) According to the design of the third step above, the photocurrent output of the same ratio is obtained (as shown in Figure 5). For example, RGB photocurrent output ratio ^ ·· i : ι. Since the two values of wavelength, light: and light area ratio are known, it is possible to use the "light response ratio and the light receiving area". The thin her hair is _ _ is the system and the coffee light current is the same. For example, the wavelength is shed, the light response ratio is micro, and the light receiving area is 29 _ =, and its photocurrent output is about 〇. (4); When the wavelength is ·, the optical response ratio is m, and the area of the illuminant is 10·50%, the photocurrent output is about 〇. Jane. As for the product of the optical response ratio and the area of the photocurrent and the photocurrent output value The existence of a 1 proportional relationship is only a basic formula, and its complete system is combined with other Weis belonging to the f-number, but this is also a good example. Please refer to the output of the photo sensor as shown in Figures 6 to 9. In the first embodiment of the present invention, the method for adjusting the ratio is to make different wavelength requirements _·, and the adjustment method Line 6 201035528 includes the following steps: • (1) Measure the response spectrum of the photosensor (as shown in Figure 6, the horizontal axis is the wavelength), wherein the photo sensor is a phosphorus Gallium, GaAs, GaAs, InP, InGaAs, A1GaInp, or Indium Gallium Nitride InGaN) photodiode (photosensitive diode of the second material), and the second photodiode (even the photodiode of the above-mentioned first material) is ultraviolet light , infrared light, blue light enhanced, or ultraviolet + blue enhanced ([JV / IR melon / O + UV + Blue Enhance) type. (2), the response of the response spectrum at different wavelengths of light response ratio (As shown in Figure 7), the resolved optical response ratio is: the optical response ratio is 35 波长 when the wavelength is 〇; the light response ratio is 99% when the wavelength is 950; The ratio is 眺; the wavelength is 删 光 light response ratio is 69%, the wavelength response is 11 ,, the light response ratio is 3〇%. In other words, when the wavelength is between 5 〇, the light response ratio is gradual Pulling high, and the wavelength is later and until the time between the discussion, the light response ratio is rapidly decreasing. Ο Light sensation #振之光光光比比. The design method is based on the following three points ~ ', according to Figure 6 The response spectrum is designed to be designed. Secondly, according to the photo-response ratio and the area of the light area, there is a certain proportion of the wire-off design of the photo-current round-off value. The third, ~ "the value of the product is proportional to the design of the wire. The three-point design basis, ^ (10) X-ray area ratio (as shown in Figure 8). The designed light-receiving area ratio is. When the wavelength is 350, the quino# and nine area ratio is 11.9%; When it is 1000, the light-receiving area ratio is 3.7%; the wavelength is 1〇5, the 'party light area ratio is 5.1%; and when the wavelength is 1100, the light-receiving area ratio is 11.8%. Change t, heart, and. The pattern of the area ratio of the light (see Figure 8) is the opposite of the light response ratio of 7 201035528 - graphics (see Figure 7). (4), get the same proportion of photocurrent output (as shown in Figure 9). Since the three values of the wavelength, the optical response ratio, and the light-receiving area ratio are known, the photocurrent output system can be calculated by the relationship between the product of the optical response ratio and the light-receiving area and the photocurrent output value. All are the same. For example, when the wavelength is 35 〇, the light response ratio is 3〇%, and the light receiving area is 1185%, the photocurrent output is about 〇. 0356; and, the wavelength is 11 〇〇, the light response ratio is 3〇%, and The party's light area is 11.78%, and its photocurrent output is about 〇〇356. As for the relationship between the product of the optical response ratio and the area of the photo-electricity and the photocurrent output value, it is only a basic type, and the complete system must be added with other variables belonging to the constant, and there is no other difference. Narration. Therefore, the second and third embodiments of the present invention can easily design a photo-current ratio of 1:1:1, and thus have a simple design or use of a power amplifying circuit, even It also has only one cost reduction effect for the tether used. Of course, the present invention can also design the photocurrent ratio required by us according to the needs (according to the second and third embodiments of the present invention), that is, any other than 丨:丨:丨, ratio, if the photocurrent output ratio is A : B : C, then the three values of A, B, and C may have partial phase, same or partial difference (for example, 1: 2 : 1), or completely different ( For example: : 2 : 3 or 3 : 4 : 5 · · · etc.) The above is only a preferred and feasible embodiment of the present invention, and thus the patent scope of the invention is not The equivalent structural changes of the contents of the book and the drawings are included in the scope of the present invention and are combined with Chen Ming. 8 201035528 .
