Cinematography Electronics
Cine Tape Measure System

Cinematography Electronics Cine Tape Measure System
The Cine Tape Measure System continuously measures the distance between the subject and the camera's film plane.

  • The Cine Tape Measure system is a small, rugged, lightweight, and quiet ultrasonic range finder that is easy to set up and easy to use.
  • Compatible with all lenses, film cameras and video cameras.
  • Continuously calculates the distance between a subject and the camera's film-plane. Continuous measuring during a shot means that small or subtle subject movements are no longer a problem. Focusing a camera lens is simplified, which saves time, avoids retakes and reduces production costs.
  • The main components are the Cine Tape Measure Control and the Sensor Assembly. The Control displays accurate distance measurements from the constant stream of data that is received by the sensors.
  • Using a 3 jointed support arm is appropriate for mounting.


How it Works

Cine Tape Measure Control
A simple one-time Film-Plane offset adjustment programs the relationship of the film plane to the sensor position. When the control detects a subject, the green Sense LED (shown in photo above) glows and the calculated distance is shown on the LED display in either feet and inches or meters and centimeters.

Adjustable brightness levels for the large red LED display offers comfortable viewing under different lighting conditions. The digital Sensitivity adjustment feature fine tunes the system range, which is also helpful with different subject reflectivity.

The Close Focus feature sets the minimum sense distance. Objects within this area are disregarded. All of the functions are set and stored digitally, safeguarding against accidental changes and provides accurate repeatability between units.

Sensor Assembly
The Sensor Assembly consists of two small cone-shaped "horns," a miniature pan tilt mechanism, a mounting stud, and an electrical connector. The horns send and receive ultrasonic signals that are used to calculate the distance measurement. Mounting the Sensor Assembly onto a camera package is simple with the combo stud. With its pan and tilt adjust/lock knobs, aiming the horns towards the subject is quick and straightforward. The Sensor Assembly interfaces to the Cine Tape Measure Control via a short detachable Sensor Cable. A spring-loaded holder permits laser pens to be attached parallel to the sensors, providing a visual reference during calibration.

A Remote Controller is available for filming conditions when the camera is mounted on a crane, mounted in an isolated location, or when a second displayed measurement is required on the opposite side of the camera package.
