Abstract
Provided is an optical displacement meter capable of enlarging an output signal region with respect to a region in which a light-receiving amount needs to be measured, a method for adjusting an optical displacement meter, and an optical displacement measuring method. The optical displacement meter includes a light-receiving element in which a maximum value of an output signal is set with respect to a boundary value, which is a maximum value of a region in which the light-receiving amount needs to be measured. The entire region of the output signal of the light-receiving element can be assigned to the valid region, in which the light-receiving amount needs to be measured with an optical displacement meter, and the optical displacement meter can have an enlarged output signal region with respect to the region in which the light-receiving amount needs to be measured.
