Abstract
System and method for calibrating the orientation or arrangement of slides in a storage receptacle. A reflective marking is asymmetrically applied to a side or edge of a slide, forming reflective and non-reflective sections. Light is directed to the slide, and a sensor detects light that is reflected by the reflective sections and generates signal or data representing an orientation of the slide. A controller processes the signal or data to determine whether the slide is properly oriented on a tray in the storage receptacle, e.g., whether the slide is flat or at an angle, upside down, rotated. The marking can be reflective ink, paint or an adhesive. Reflective and non-reflective markings can also be formed by laser etching, polishing, or by frosting.
