A non-contact electronic level has a light source, a vial having a bubble and positioned to be irradiated by light from the light source, and a photo sensor located at a position corresponding to the bubble at a fixed distance from the vial. The photo sensor captures an image of the bubble after the vial is irradiated by the light source. An image processing unit is electrically coupled to the photo sensor and converts the image of the bubble into an electronic level signal by comparing the centroid of the image of the bubble with a predetermined point.

A laser indicator has a laser mechanism having three laser generators generating laser beams perpendicular to each other. Each of the three laser generators is electrically coupled to a separate laser control motor for independent control of the beam of the corresponding laser generator. The laser indicator further includes an adjusting mechanism including a control circuit module, a frame having an adjustment support associated therewith, and a plurality of level control motors disposed in the frame. The laser indicator also includes a laser generator adjuster and tightener.

A laser receiver for detecting the position of incidence of a beam of laser light thereon includes a first photodetector and a second photodetector aligned in series with each other and spaced apart from each other by a gap. If the laser is evenly distributed between the two photodetectors, then the laser position will be set as the correct position and a corresponding signal will be displayed. However, if the first photodetector detects more light than the second photodetector, then a signal will also be displayed to inform the user that more laser is being projected onto the first photodetector. On the other hand, if the second photodetector detects more light than the first photodetector, then a signal will be displayed to inform the user that more laser being projected onto the second photodetector. These signals will assist users to adjust the laser receiver to accurately position the laser.
