Description
Technical field
The utility model relates to plant leaf blade spectrum detection technique field, is specifically related to the three-dimensional photodistributed pick-up unit of a kind of plant leaf blade.
Background technology
Plant leaf blade can produce reflected light and see through blade epicuticle, mesophyll tissue, lower epidermis etc. at the lower surface generation transmitted light (as shown in Figure 1) of blade under the irradiation of light at the upper surface of blade.It is not equally distributed that blade upper surface reflected light distributes at the blade upper space, and transmission neither evenly distribute.
Spectral range from 400nm to 2500nm, can be divided into three parts: be that the light absorbing ability of photosynthetic pigments is stronger in the visible light characteristics of 400-800nm, the absorption of near infrared region (800-1100nm) is subject to dry, yet but be the zone that Order Scattering occurs, reason is that the blade intermediate structure has many tiny air partly to promote reflection and transmission level; In the 1100-2500nm mid infrared region strong absorption being arranged also, mainly is in the pool in bright leaf district, secondly is the dry of withered leaf.
