Optical Encoder in Mechatronics : Incremental & Absolute Sensors : Mechatronics Lectures



this optical encoder is at position position senses which are used to find the position there are parts like source or saber accelerates or picker and Cora this is mainly related to in criminal and absolute senses criminals and sub there is a source they also see much and there is in this in that this there are several holes from salsa to the receiver it might be will be passive and suppose if everyone is in between this source and receiver the light will pass without any obstructions and see one is able to get or I will see this nice if suppose if this discourage the pop a part of me will between this source have to savor then never see what this not yet it might be so that if the fastest we will get it we will resume of the sisterhood if the second is the receiver fatty such that this blackness will be do since that we are getting in further with the rotation of this disc so we are able to get the hammer with which the this carburetor by duty in this output so this is what what increment them this encoder do but here if we only know the initial position we are able to find in the final position so in this way with a particular hole we are able to move the position so there is absolutely no obviously actually that border separate the code for each question that we will come to know suppose these are four sources there will be four receivers first position is this one here from all these source light will be imaging and here there were before receivers and then first receiver will get the delight second receiver will also be polite the herbalist email will look there is no one there is no person so forth because of that the receiver will get no light and a photon will be getting less than the out nineties so for this particular position there is a particular output suppose in the second position suppose I this is the second question for convenience I have avoided the points in between for getting the idea clear here in the second position we will get all four position one four receivers will be receiving the light so that the second position will be or these four positions will be white now suppose if the rotation is taking place in the anti-clockwise direction then this part will be coming here then the first position Buster similarly at night second will be of bed here and what will you be next so that the output make this one for each position there are separate output so we are able to provide it as a plane cause for separate position so we call it as an absolute income so this is what an optical encoder you
