processing developed and patented by Heliotis is the core of all our products. In our proprietary CMOS image sensor, phase-sensitive demodulation does not take place in the downstream signal path, but directly at each pixel. Each pixel performs a synchronous I\/Q measurement and outputs a 10-bit In-Phase (I) and 10-bit Quadrature (Q) value (dual-phase demodulation). With I and Q, the amplitude and phase of the useful signal can be determined immediately \u2013 across the entire area, stably and reproducibly.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-1587919 e-con-full e-flex e-con e-child\" data-id=\"1587919\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-3d2bd45 elementor-widget__width-initial elementor-widget-mobile__width-inherit elementor-widget elementor-widget-text-editor\" data-id=\"3d2bd45\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>This pixel-parallel demodulation suppresses constant background, 1\/f noise, and non-synchronous interference light right at the point of acquisition, so that even very small, modulated signals become reliably visible \u2013 without long averaging times. The platform is available in two resolutions: heliCam\u2122 C4 (512 \u00d7 542 pixels) and the high-resolution heliCam\u2122 C4M (1024 \u00d7 1102 pixels). Thus, the C4 platform opens the way to massively parallel lock-in imaging \u2013 the technological foundation of our camera family.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-915b057 elementor-widget__width-initial elementor-widget elementor-widget-image\" data-id=\"915b057\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" src=\"https:\/\/www.heliotis.com\/wp-content\/uploads\/2025\/08\/heliSensS4IQ3.svg\" title=\"heliSensS4IQ3\" alt=\"heliSensS4IQ3\" loading=\"lazy\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-75bd7ec e-flex e-con-boxed e-con e-parent\" data-id=\"75bd7ec\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-9698837 elementor-widget elementor-widget-html\" data-id=\"9698837\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"html.default\">\n\t\t\t\t\t<div class=\"heliotis-table-outer\" data-caption=\"Vergleich der heliCam\u2122 C4 & C4M Modelle\">\r\n  <div class=\"heliotis-table-wrap\">\r\n\r\n    <table class=\"heliotis-tbl scroll-mobile\">\r\n\r\n      <thead>\r\n        <tr>\r\n          <th>Feature \/ Model<\/th>\r\n          <th>C4.0-S40<\/th>\r\n          <th>C4.0-S40U<\/th>\r\n          <th>C4.0-S41U<\/th>\r\n          <th>C4M.2-S4M1U<\/th>\r\n        <\/tr>\r\n      <\/thead>\r\n\r\n      <tbody>\r\n\r\n        <tr>\r\n          <th scope=\"row\">Lock-in Pixel<\/th>\r\n          <td>542\u00d7512<\/td>\r\n          <td>542\u00d7512<\/td>\r\n          <td>542\u00d7512<\/td>\r\n          <td>1024\u00d71102<\/td>\r\n        <\/tr>\r\n\r\n        <tr>\r\n          <th scope=\"row\">Demodulation Frequency<\/th>\r\n          <td>305 Hz \u2013 134 kHz<\/td>\r\n          <td>305 Hz \u2013 134 kHz<\/td>\r\n          <td>305 Hz \u2013 134 kHz<\/td>\r\n          <td>305 Hz \u2013 50 kHz<\/td>\r\n        <\/tr>\r\n\r\n        <tr>\r\n          <th scope=\"row\">Full Well Capacity (FWC)<\/th>\r\n          <td>500 ke<sup>\u2013<\/sup><\/td>\r\n          <td>500 ke<sup>\u2013<\/sup><\/td>\r\n          <td>125 ke<sup>\u2013<\/sup><\/td>\r\n          <td>140 ke<sup>\u2013<\/sup><\/td>\r\n        <\/tr>\r\n        \r\n              <tr>\r\n          <th scope=\"row\">Fill Factor<\/th>\r\n          <td>21%<\/td>\r\n          <td>55%<\/td>\r\n          <td>55%<\/td>\r\n          <td>55%<\/td>\r\n        <\/tr>\r\n\r\n        <tr>\r\n          <th scope=\"row\">Dynamic Range for Signal<\/th>\r\n          <td>2 \u00d7 10 bit (X, Y)<\/td>\r\n          <td>2 \u00d7 10 bit (X, Y)<\/td>\r\n          <td>2 \u00d7 10 bit (X, Y)<\/td>\r\n          <td>2 \u00d7 10 bit (X, Y)<\/td>\r\n        <\/tr>\r\n\r\n        <tr>\r\n          <th scope=\"row\">Common Mode Suppression<\/th>\r\n          <td>21 bit equivalent<\/td>\r\n          <td>21 bit equivalent<\/td>\r\n          <td>21 bit equivalent<\/td>\r\n          <td>18 bit equivalent<\/td>\r\n        <\/tr>\r\n\r\n      <\/tbody>\r\n\r\n    <\/table>\r\n\r\n  <\/div>\r\n<\/div>\r\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-5e5c0dc e-flex e-con-boxed e-con e-parent\" data-id=\"5e5c0dc\" data-element_type=\"container\" data-e-type=\"container\" id=\"integration\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-eabe940 elementor-widget-mobile__width-inherit elementor-widget-tablet__width-inherit elementor-widget__width-inherit elementor-widget elementor-widget-heading\" data-id=\"eabe940\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<div class=\"elementor-heading-title elementor-size-default\">SDK, Viewer, and Interfaces<\/div>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-54c4881 elementor-widget__width-inherit elementor-widget-mobile__width-inherit elementor-widget elementor-widget-heading\" data-id=\"54c4881\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Connection and Integration<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-da6682c elementor-widget__width-initial elementor-widget-mobile__width-inherit elementor-widget-tablet__width-inherit elementor-widget elementor-widget-text-editor\" data-id=\"da6682c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>The heliCam\u2122 C4 is connected via the heliDriver\u2122 D3 module, which powers the camera and serves as a synchronization interface.
