Abstract

A method based on irradiation of a part of a cocoon not darkened by a pupa, which excludes the influence of interference on the accuracy of control of the cocoon, and a block diagram of a device implementing this method are considered. It is shown that the most effective optical scheme for constructing an optoelectronic converter is a scheme with spatially distributed emitters and photodetectors, which excludes the influence of oscillations of the controlled cocoon in the control zone. A functional diagram is presented and the principle of operation of an optoelectronic converter for the density of a cocoon shell, built on the basis of the proposed optical scheme, is considered.
