+====== LabLisp Host ======
-Lisp host is ...
+Lisp host is a mechanism for exposing functionality of Qt program as LabLISP functions. LabLispHost is a virtual Qt/C++ class that - when inherited - provides this mechanics. The approach is quite simple and modular in Qt/C++. Single Qt program can contain several LabLispHost classes, that are initialized at the program's startup.
-We have several ...\\
+In LabLISP, the host classes are implemented as LISP packages with symbols naming the hosted functions. These packages are available to the LabLISP environment from start of the hosting program.

-  * [[ch3_1_standa]]
+At present, we have LabLISP tightly integrated in control programs for our infrared and THz ellipsometers. Program //TellMagSoft// controls combined THz and infrared magneto-ellipsometer //TellMag// in our lab at UniFr. Similar, but simpler program //IrElliSoft// controls our standard infrared ellipsometer (see below).

-  * [[ch3_1_opus]]
+Each LabLISP host class provides simple package name and longer descriptive label for user convenience.
+==== TellMagSoft ====
+As the //TellMag// instrument consists of several subsystems, the LabLISP integrated to //TellMagSoft// has access to their control via several packages.
+  * [[ch3_1_tms|TMS]] - TELLMAGSOFT-DISPATCHER, control and data management functions of the software itself
+  * [[ch3_2_gage|GAGE]] - GAGE-COMPUSCOPE, control of acquisition card for the TD-THz part
+  * [[ch3_3_standa|STANDA]] - STANDA-CONTROLLER, multi-axis controller for polarizer motors
+  * [[ch3_4_smaract|SMARACT]] - SMARACT-CONTROLLER, controller for the piezo beam positioners
+  * [[ch3_5_opus|OPUS]] - BRUKER-OPUS, communication with Bruker 70v OPUS software
+  * [[ch3_6_tcon|TCON]] - LAKESHORE-TEMPERATURE-CONTROLLER, sample temperature control
+  * [[ch3_7_magnet|MAGNET]] - CRYOMAGNETICS-MAGNET-CONTROLLER, control of magnetic field
+==== IrElliSoft ====
+The infrared ellipsometer has fewer components and //IrElliSoft// hosts following packages for their control:
+  * [[ch3_2_1_elli|ELLI]] - IR-ELLI-DISPATCHER, control and data management functions of the software itself
+  * [[ch3_2_2_opus|OPUS]] - BRUKER-OPUS, communication with Bruker 70v OPUS software. The control in IrElliSoft is bit upgraded from the older TellMagSoft version. In the future, both programs will use the same interface to opus.
+  * [[ch3_2_3_tcon|TCON]] - SCIENTIFIC-INSTRUMENTS-TEMPERATURE-CONTROLLER, sample temperature control
+  * [[ch3_2_4_pam|PAM]] - POLA-ANA-MOTORS
+  * [[ch3_2_5_flip|FLIP]] - STATIC-COMPENSATOR-FLIPPER
+  * [[ch3_2_6_rce|RCE]] - MICOS-POLLUX-RCE, controller for the MIR rotating compensator
+The device classes internally inherit from THardwareDevice which inherits the LabLispHost. THardwareDevice class provides C++ abstraction for controlled axes (motor positions, temperature, field) and some of the controller LabLispHosts then provide symbols representing those axes in LabLISP.
