HD
Hazard Distance (HD) is the distance measured from the projection lens at which the intensity or the energy
per surface unit becomes lower than the applicable exposure limit on the cornea or on the skin. The light beam
is considered (to be) unsafe for exposure if the distance from a person to the light source is less than the HD.

DMD
A digital micromirror device, or DMD, is an optical semiconductor that is the core of DLP projection technology.
Dew point
The dew point is the saturation temperature for water in air. The dew point is associated with relative humidity.
A high relative humidity implies that the dew point is closer to the current air temperature. Relative humidity of
100% indicates the dew point is equal to the current temperature and that the air is maximally saturated with
water. When the moisture content remains constant and temperature increases, relative humidity decreases.
Scheimpflug principle
The "plane of sharp focus" can be changed so that any plane can be brought into sharp focus. When the DMD
plane and lens plane are parallel, the plane of sharp focus will also be parallel to these two planes. If, however,
the lens plane is tilted with respect to the DMD plane, the plane of sharp focus will also be tilted according to
geometrical and optical properties. The DMD plane, the principal lens plane and the sharp focus plane will
intersect in a line below the projector for downward lens tilt.

DMX
DMX-512 Lighting protocol over RS-485 interface. Carries information of 512 channels from a lighting
controller to lighting devices. Standardized by USITT.
RS232
An Electronic Industries Association (EIA) serial digital interface standard specifying the characteristics of the
communication path between two devices using either D-SUB 9 pins or D-SUB 25 pins connectors. This
standard is used for relatively short-range communications and does not specify balanced control lines. RS-
232 is a serial control standard with a set number of conductors, data rate, word length and type of connector
